The invention relates to the field of geophysical exploration methods, in particular vibroseismic, and can be used in conventional schemes geological exploration, exploration, and investigation of deposits of metallic and nonmetallic minerals, including water, mainly for areas with known structure semajno be decomposed into two stages: field, first, seismic surveys and drilling. The first stage is incomparable to the cost of the second. In addition, drilling in any case violate the environmental conditions in the surrounding area, and in areas with a developed structure of settlements or in areas with high sensitivity to external influences (in particular, in the permafrost zone) drilling, the more laid incorrectly, can lead to environmental disaster. For these reasons, in recent times the maximum attention to the development of the field, primarily seismic methods to more accurately determine the potential search area and the location of the well.The technical problem to be solved by the present invention is directed, is to develop ways of prospecting, exploration and investigation of mineral deposits with high predictive accuracy.The technical result is obtained as a result of implementation of the invention is to reduce the cost of exploration, efficiency and effectiveness of monitoring operation of mineral deposits, as well as the improvement of the ecological situation in the region searches th result is achieved by using the search method: exploration, research, modeling, reserves estimation and monitoring of mineral deposits.This method involves drilling or use of Fund existing wells and geophysical and geotechnical studies of wells and field geological, geophysical, geochemical and aerospace work, providing the formation of: - frame made of sections of cubes, intervals (slazav) wells-standards-based processing and interpretation of geophysical and geotechnical information about the wells using deterministic (analytical and petrophysical) and raspoznavaniya statistical dependencies and techniques (factor, cluster, regression, component, and other analyses, including correlation of borehole sections-standards; - correlation model to the entire set of wells based on the use of the framework and correlation schemes wells-standards using deterministic-statistical dependencies, including splitting incision wells on lithologic-technological types, as well as the formation of tracks-or GIS presents the correlation skvazhina-logging or skvazhina-parametric (porosity, permeability, clay content, Neptune the awn surface sections, intervals (slazav) or cubes for inter-well and borehole environment; - frame from seismic or complex (seismic, gravity, electrical and other) in depth or time scale or set raznomestnyh combined time and/or depth of the incisions, superficial cuts, intervals (slazav) or cubes. Additionally, conduct geophysical and geological studies of wells in the study area. Above information borehole and geotechnical cut surface of the slice interval (slise) or cube implement standard transformations, such as the transformation of information discreteness logging or seismic field carried out over the entire complex, including seismic, electrical, gravimagnetic, and other integrated geophysical, geochemical and pseudo-potential information. By the Hilbert transform build incisions, cuts, slazy or Cuba instantaneous frequency, instantaneous amplitude and instantaneous phase, and other transformations and their pseudoalloy for fields aseismically nature. Similarly transform borehole information objects, receive sets (sequences) of properties at each point selected the wells. Perform the split sections of wells on lithologic-technological classes-types, consistently using an iterative deterministic and statistical methods estimates the similarities and differences without teaching and learning. Fix and determine the number of classes. Calculate reservoir and physical properties. Between wells hold multiparameter correlation, extrapolation and interpolation properties in section, the section, interval (clause) and a cube with a given number of classes, forming the frames of the wells-standards and geophysical profiles, sections, slezov or cubes. Classify spatial, inter-well and borehole objects based on the mapping of the generated frames and previously obtained properties in the wells and in the inter-well and borehole space with obtaining the result of the cut, slice, slisa or cube with a pre-defined number of classes, lines or surfaces tectonic and lithologic-stratigraphic disturbances and substitutions, the list of the most informative source properties-features, ranked according to the degree of informativeness, on the basis of the received or used deterministic petrophysical, analytical and raspoznavaniya-stativ with the necessary resolution (seismic or logging) calculate (synthesize) and build sections, slices intervals (sliz) or cubes model field reference and the most likely routes is presented or GIS presents comprehensive sets pseudochina (synthetic) and field geological and geophysical tracks-presents the original and the transformed curves effective and original properties, components of many synthetic wells (pseudospin), and form the geological-geophysical and geological model of the Deposit, comparing the results obtained with the history of the development of the field, results in newly drilled wells or already known mineral deposits or parts of such deposits from the same geological structure, judged both on the Deposit and its geological, geophysical, geochemical characteristics, including the extent and categories of reserves, the extraction of minerals, recommendations for the development, projected development and production, particularly in areas of primary, secondary and tertiary impacts on the reservoir, in the case of liquid and gaseous hydrocarbons in areas of prospecting and exploration of solid minerals is etali use selective fragments of wells and geophysical profiles. Mostly use non-reference classification. In the presence of one well it is used the same way as described above. In the presence of one well or its spatial information fragments used to create Pseudocalanus in different parts of the examined slice, cut, cliza and Cuba. In the absence of wells-standards are used as Pseudocalanus for the classification of selective spatial information fragments integrated geophysical and local geophysical (e.g., seismic and geotechnical fields, and for quantitative calculations pseudoalloy mimic of these fragments by known statistical dependencies, or borrow from the territories (including contiguous) with similar geological conditions. Where there is only one source fields used in the same way as described above. In the classification carried out varying the number of classes. Usually advanced restore features of GIS and the GTI in wells on GIS data on other wells using numerical methods using complex GIS data, GTI and field methods. Preferably over pseudococaine perform analytical steps, is in search recount seismic data from the temporary in-depth view with a preliminary calculation of the above standard transformant, including converting Gilbert, PAK and peak (walevet) conversion, and the resulting information used for mathematical processing and classification of the received objects. Mainly in addition to the Hilbert transformation on the basis of interval velocity analysis in wells and seismic data, as well as on the basis of models of different physical quantities in wells or a priori ideas about the minimum and maximum values of these quantities in wells build incisions interval, average and effective speed, pseudoacoustic and peak (wavelet) transforms of these quantities and their gradients, using them to build models of the field. Usually used as a standard transformant averaged assessment process, integrated geophysical, local geophysical, such as seismic wave fields are the same for all points of the section intervals, or planar slices, or slezov, or cubes. Mainly in the set of specified physical quantities using the density, Poisson's ratio, compressibility and acoustic stiffness, amplitude-frequency and phase characteristics; combinations thereof, and transformants for longitudinal and Popeye can use density, compressibility, volume or weight content of minerals or elements, porosity and permeability, or other quantitative characteristics of the breed. When interpolating, extrapolating, the classification and construction of synthetic wells using methods of cluster analysis. In the absence of the original continuous lithological division of wells split sections of the reference and/or an entire set of wells on the lithological technology classes-types of methods of cluster analysis carried out on all of the source set of wells on the basis of a limited set of markers, traced all the wells, or at their most visually or by typical numerical values of borehole fields, or by a known selective lithotypes. Usually the split sections of wells on lithologic-technological classes produced by the methods of cluster analysis along the trunks of every well known layers (interlayers-benchmarks). In addition, the split sections of wells on lithologic-technological classes can produce methods of cluster analysis as along each well and across multiple wells on a single set of layers (interlayers-frames). In the absence of originally there is tin wells. When there is a frame breaker reference wells along the boreholes classes-types and available geophysical, geometric and parametric frame and frame multiparameter correlation, extrapolation and interpolation in section, the section, interval (clause) or Cuba, the classification and construction of synthetic wells carried out automatically or semi-automatically, given a tectonic disturbance, pinch-outs and substitutions. When there is a frame breaker wells, but in the absence of frames wells and geophysical and parametric fields - classification using interactive mode. In numerical calculations, in particular, use regression with degrees or other nonlinear functions. When interpolating, extrapolating, the classification and construction of synthetic wells use the search method of cohesive elements in the property space. For calculation of reference or synthetic (pseudosciaena) curves use the pre-generated and dynamically updated standard Bank petrophysical probabilistic-statistical and analytical dependency of type "setting-option", "option-sign", "sign-a sign" for well and field and heat is the first field on the basis of pseudochina (synthetic) curves using the following criteria:- notorious defined layer or interlayer, when the resistance layer

Usually use the method of two or more reference layers with known properties and field values from the solution of the equations which define the required reading fields in the matrix, fluid, and structural adjustment factors, and calculations of density (or porosity) of the SCC use of the formulas and methods described earlier. Mainly the most typical reference clay find the minimum functionality that is dependent on the, spectrometry GC, absorption, attenuation. For calculation of shale use the dependence of natural radioactivity YTCand clay content Y=RCTOCHwhere K and R is a structural coefficients depending on ones, elebrities, mineral composition of clays. In the formation of geological-geophysical and geological models of oil and gas fields on the basis of pseudochina (synthetic) curves find the area of fracture by at least functional of the instantaneous frequency, compressibility, interval velocities of longitudinal and transverse waves, Poisson's ratio, resistivity of the structural coefficients of the electric and seismoacoustic, the slow speed of the internal porous-fluid wave (like BIO), absorption, attenuation. Usually after building sections, slezov, sections or cubes interval velocities, Poisson's ratio, compressibility and pseudoacoustic analyze the main components of slices, slezov, sections or cubes, and the main factors slices, slezov, sections or cubes. In case of availability of data on potential and quasi-potential fields use their analytic continuation up and down and transformants (difference, amount, density, the areas in section, slice clause or Cuba as an informative set of source data. In the case of newly drilled wells with GIS data and the GTI after classification compare the obtained data with GIS data and the GTI to conclusions about the accuracy and reliability of forecasts. In the presence of electrical information on the location of the search is carried out by its binding to the deep representation of the potential and/or seismic data through extrapolation or interpolation.In a preferred embodiment, the proposed method is implemented as follows.Form a seismic section, surface cut, slais (interval) or cubic Conduct geophysical and geological exploration in the search space. On the seismic section, surface cut, Slauson or cube carry out the transformation. The same transformation shall be operated over the entire complex downhole geophysical and geotechnical information. By the Hilbert transform build incisions, superficial cuts, sliz and Cuba instantaneous frequency, instantaneous amplitude and instantaneous phase. Get the set of properties for each point. Similar procedures carried out over skvazhin the beating of borehole sections on lithologic-technological classes-types, consistently using an iterative, deterministic and statistical methods estimates the similarities and differences without training and with training, fix and determine the number of classes. Between wells hold mnogopredmetnoy correlation and interpolation properties in the cut surface of the slice, clause or a cube with a given number of classes. Classify all spatial inter-well and borehole objects on the basis of prior property which results in the cut surface of the slice, slisa or cube with a pre-defined number of classes, lines, tectonic and lithologic-stratigraphic unconformity, the list of the most informative properties, ranked by the degree of informativeness. On the basis of determining the dependence of the results of geophysical surveys of wells from previous build properties sections or cubes pseudosquare with pseudococaine curves and comparing the results with known mineral deposits with the same geological structure, is judged on the presence of the Deposit and its geological, geophysical, geochemical and technological characteristics. Preferably after the implementation of the Hilbert transform maximalnych values of these quantities in the wells building sections pseudoacoustic for these quantities. Preferably when classifying using the search method of cohesive elements in the space of properties or methods of cluster analysis. Usually as these physical quantities used acoustic stiffness for seismic waves. Mainly after building sections or cubes pseudoacoustic analyze the main components of the sections or cubes, and the key factors sections or cubes. Usually in case of availability of data on potential fields use their analytic continuation and the transformants in the form of tracks-view in cross-section or a cube as an additional source of data. Mostly in popularity of GIS data and the GTI after classification compare the obtained data with GIS data and the GTI.When implementing the method in the traditional way conduct geophysical exploration wells. Also traditional methods of seismic receive seismic transect, surface cut, slays or cubic On the seismic section, the surface of the slice interval (Slauson) or cube for characterizing the properties of each point in the original space-time seismic field perform standard operations transformation: bandpass filter 4 is I, homomorphic filtering, homomorphic deconvolution, the zero-phase deconvolution, removal of linear trends amplitudes and mean values of the amplitudes. Then, by Hilbert transformation on the original cut surface of the slice, Slauson or cube obtained from the transformations and transformations cuts instantaneous frequency, instantaneous amplitude and instantaneous phase. Get the geometric characteristics of each pixel in the original cut, slice, slisa or cube in the form of a set of properties representing a set of values, incisions, superficial cuts, slazy or cubes which were obtained previously. These properties of points will be considered as coordinates of points in a multidimensional space properties. The same transformation shall be operated over the entire available integrated borehole, geophysical and geotechnical information. Separately for wells perform classification, identify classes and their number with the given number of classes and conduct inter-well and borehole correlation and interpolation of the resulting properties. In these procedures, the methods they use to assess the similarity as without education and training. On the basis of prior property (coordination is oisca related items in the property space. In the classification have the cut surface of the slice, slays or cube that contains the split points on a predetermined number of classes, line, or surface tectonic and lithologic-stratigraphic unconformity, a list of the most informative properties, ranked by the degree of informativeness and quality assessment classification. According to the results of the classification exercise the binding of the resulting cut surface of the slice, slisa or cube to the geological, geotechnical or geophysical frames or lithological columns in wells with getting extrapolation of geological, geotechnical or geophysical frames or lithological types for the entire cut surface of the slice, slays or cubic Perform all of the above standard transformative and meaningful operations on wave and potential fields, as well as the quasi-potential fields, including attraction, the translation up and down, and the other transformation potential and quasi-potential fields with the binding in the form of deep or temporary tracks-view in each geometric point of the original cut surface of the slice, slisa or cube. Conduct classification of sections, EEPROM, extrapolate and interpolate these frames for seismic or potential (quasi-potential) the cut surface of the slice or cube building incisions, superficial cuts, slezov and cubes forecast of geological, geographical and geological characteristics (properties) and an estimate of their uncertainty. On the basis of the previously obtained parameters wells building sections, planar slices, slazy or cubes pseudosquare with pseudococaine curves. Under pseudochina curve refers to the forecast curve of any geophysical parameter, measured in real well determined (predicted) in any place in the earth's crust under the assumption that there well was drilled. A forecast can be made in the form of pseudosections tracks-view or tis-view. Set pseudochina curves predicted in any one place of the earth's crust, called pseudochina. The retrieval operation pseudosquare is to create a mathematical model for each CMP or the deepest point of another method of accumulation (DIR, PRO ERA and others) on the basis of known and computed fields new fields pseudochina curves representing the extrapolation of sovokupnostei any of the logging characteristics: resistance, natural gamma activity, neutron logging, logging density, porosity, velocity, etc., In the simulation it is possible to estimate the reliability of obtaining pseudoceratina (pseudosciaena) incision or cube. Pseudoceratina curve is a term equivalent pseudochina curve. Pseudocertainty (pseudosciaena) cube is a set pseudochina curves, geolocated to any area of the Earth's surface like a seismic cube. Each model pseudochina curve and pseudosciaena in General, generated operations on traces CMP or another method of accumulation (DIR, PRO ERA and others) and their transformants and/or trails-concepts of potential and quasi-potential fields and their transformant in each geometric point of the investigated volume, characterized by estimates of the reliability of model building and enables the implementation of the classical approach to each pseudochina curve with position automatic or manual interpretation methods of logging (GIS): correlation of lithological subdivision, define the parameters estimates of reserves and field development. This leads to the obtaining of the independent geological and technological ago object (section, slice or cube) for more reliable interpretation or re-interpretation of geophysical fields and their combination according to the technology described above. By comparing the obtained results with the known field with similar Geology judge the presence or absence of deposits in the search space and, in the presence of the field, its geological, geophysical, geochemical and technological characteristics.In the absence of a solid integrated seismic, potential or GIS, GTI and lithological characteristics along the boreholes as a benchmark preferably used for vertical and horizontal correlation and interpretation of sample fragments, including on the basis of visual analysis or ciclovir values. In the absence of standards in the context of the wells or in the inter-well and borehole space predominantly use non-reference classification, including at least open the way. Clustering and classification of possible variation of the number of classes, and the number and mutual arrangement of the classes make a judgment about the accuracy of the correlation of the wells. In the absence of x is the GTI in some wells on GIS data on other wells using regression, deterministic or any other numerical methods using complex GIS data, GTI and field methods. Preferably in the study of pseudosquare use the same techniques and methods as in the study of real wells. Mainly interpolation between wells, correlation or building pseudosquare carried out within the boundaries of classes, clusters of taxa, tectonic or calculated estimates or interactively intervals.Along with the implementation of the Hilbert transform on the original incision or cube it is possible to build on the basis of models of different physical quantities in wells or a priori ideas about the minimum and maximum values of these quantities incisions, cuts, slezov or cubes PACK or peak (wavelet) transforms to these values. As these values are preferably used acoustic stiffness for longitudinal or transverse waves and other quantities (velocities of longitudinal and transverse acoustic waves and porosity). In the case of data availability anomalous values of gravitational and magnetic fields and data on the value of the velocity of longitudinal waves build sections or cubes of these fields and their PR is C and calculate the transformant of these fields. Before the classification of objects previously defined properties may be subjected to additional principal component analysis and analysis of key factors, in particular, by the method of minimum load. This allows you to choose the combination of principal component or the main factors that explain a significant portion of the variance. The result from the entire set of properties will be selected only those properties which are linear combination of the original properties and linearly independent from each other. Analysis of the resulting classification of the incision can be carried out using the obtained at the stage of formation of a seismic section data geophysical and geological exploration (TIS) and the GTI. In this case, the use of GIS data and the GTI can be made binding obtained, and hence the original cuts to GIS data and the GTI, as well as extrapolation of geological reference points on the transect. Can be used regression analysis based GIS data and the GTI from cuts and cubes, characterizing the properties of objects, or held interpolation of GIS data and the GTI in the property space with the construction of sections or cubes forecasts GIS data and the GTI and estimates their neop the de linear combinations of new linearly independent orthogonal properties - the main component. In addition to get information about the contribution of the main component in information about the environment. It may be that the incision of some major components, such as the first principal component, significantly more informative characterizes geological cross-section compared to the original seismic section. As a result, the set of source properties at each point is replaced by a set of principal components orthogonal properties, ranked by degree of contribution to information about the environment.Adding to the already existing data sections pseudoceratina (pseudosciaena) curves allows to significantly increase the information content of the data used for further interpretation of the material with the higher accuracy of the prediction of the presence of the field and its characteristics.In the invention will be further illustrated by the following example.When searching for underground water-bearing formation in Central Asia was held ordinary complex seismic and gravimetric and magnetic surveys. Over the received seismic wave field were conducted by the above transformation, the analysis of the power spectrum, the calculation of the instantaneous dynamic characteri - continuation fields up and down, getting tracks-views potential fields, calculation of derivatives and gradients. The results obtained were used to obtain interval forecasts of water availability on pseudoceratina characteristics based on the classification in the feature space.Lighter in color stations were concentrated in the upper part and the center received a cut, and dark areas are located in the lower part, and the right and left of center. According to petrophysical and geological views it highlights classes indicate well defined layers (high porosity, low seismic velocity, the absence of high-frequency magnetic anomalies, the outputs in the near-surface layers in the form of keys on adjacent squares).The drilling results have confirmed the correctness of the prediction about the presence of an aquifer.Using the proposed method allows to reduce the cost of exploration, to increase the efficiency and effectiveness of control exploitation of mineral deposits, as well as to improve the ecological situation in the region search fields by reducing the number oshibochnie frame of incisions, cubes and/or slazav wells-standards on the basis of drilling operations and Fund existing wells, taking into account the geophysical, geochemical and geotechnical studies of wells and field geological, geophysical, geochemical and aerospace work, as well as the processing and interpretation of geophysical, geochemical and geotechnical information about the wells using deterministic and raspoznavaniya statistical dependencies and techniques, including correlation of borehole sections-standards, form a correlation model of the entire set of wells based on the use of the framework and correlation schemes wells-standards using deterministic-statistical dependencies including splitting incision wells on lithologic-technological types, and form the tracks - and GIS-presents the correlation skvazhina-logging and skvazhina-parametric, including pseudochina sections, with a given discrete surface sections, slezov and cubes for inter-well and borehole environment, form the frame of seismic and comprehensive in-depth or time scale and sets combined time and the depth of the incisions, superficial cretin in the study area, above information borehole and geotechnical cut surface of the slice, cliza and Cuba are doing the standard transformations, such as the transformation of information discreteness logging and seismic field carried out over the entire complex, including geophysical, geochemical and pseudo-potential information via the Hilbert transform build incisions, cuts, sliz and Cuba instantaneous frequency, instantaneous amplitude, instantaneous phase and their pseudoalloy for fields aseismically nature, similarly transform borehole information objects that have the property sets in each point of the investigated space-time volume, including sets of properties for each point along the boreholes, perform the split sections of wells on lithologic-technological classes-types, consistently using an iterative deterministic and statistical methods estimates the similarities and differences without training and with training, fix and determine the number of classes, calculate the reservoir and the physical properties between wells hold multiparameter correlation, extrapolation and interpolation properties in the cut, slice, clause and Cuba with thedancefactoryuk spatial, inter-well and borehole objects based on the mapping of the generated frames and previously obtained properties in the wells and in the inter-well and borehole space with obtaining the result of the cut, slice, cliza and a cube with a pre-defined number of classes, lines, and surfaces tectonic and lithologic-stratigraphic disturbances and substitutions, the list of the most informative source properties-features, ranked according to the degree of informativeness, on the basis of the received and used deterministic petrophysical, analytical and raspoznavaniya statistical dependencies of the results of geophysical, geochemical and geotechnical studies of the wells from the previous properties-signs with the necessary discretion calculate and build sections, slices, sliz and Cuba model field reference and the most likely routes is presented and GIS presents comprehensive sets pseudochina and field geological, geophysical, geochemical and geotechnical tracks-presents the original and the transformed curves effective and original properties that make up many pseudosquare, and form of geological-geophysical and Geology the deposits, results on newly drilled wells and from known mineral deposits and parts of such deposits from the same geological structure, judged both on the Deposit and its geological, geophysical, geochemical characteristics, including the extent and categories of reserves, the chemical composition of the oil and gas, extraction of minerals, recommendations for the development, projected production and flow rates, in particular in areas of primary, secondary and tertiary impacts on the reservoir in the case of liquid and gaseous hydrocarbons, in areas of prospecting and exploration of solid minerals and aquifers.2.
