 Method to determine platinum-palladium and copper-nickel metallogenic trend of basite-ultrabasite laminated massif of archean crystalline shield / 2506613Invention relates to methods of complex determination of metallogenic trend of basite-ultrabasite laminated massifs of Archean crystalline shields and may be used for separate prediction and searching for industrial objects of platinum-metal and copper-nickel mining materials. Substance: relation is established between genesis of laminated massif with geodynamic environment of rifting. Samples are taken, analysed, and substantial and mineralogical composition of petrographical varieties of rocks along the cut of the massif. Sections of most contrastive composition of magmatic series lamination and borders are identified. Concentration of isotopes U, Pb, Sm, Nd is measured in minerals and rocks of analysed samples. Absolute ages of rock varieties are calculated, as well as total duration of formation of laminated massif and value of an isotope indicator of massif rocks. Produced data is compared with indicator values of ages and duration of formation of laminated massif, and also values of the isotope indicator. A conclusion is made on prospectivity of the tested laminated massif for platinum-palladium or copper-nickel metallogenic trend. Additionally on the basis of data of geophysical research with account of the composition of depth crustal xenoliths and age of depleted matrix, they estimate the composition of the lower crust and the upper mantle for availability of the granulite-basite layer in the crust base. This layer creates favourable conditions for preliminary concentration of metals of the platinum group and is characterised by speed of longitudinal waves on the border of transition from the crust to the mantle Vp=7.7-7.1 km/s. Further they determine the mode of rifting development on the basis of the criterion of margin or continental type. At the same time formation of the basite-ultrabasite massif at the initial stage of the continental rifting testifies platinum-palladium metallogenic trend, and on the completing stages of rifting of margin type - copper-nickel metallogenic trend. Duration of the laminated massif formation is calculated with differentiation into ore and barren magmatic stages. Age intervals are determined for formation of ore mineralisation of platinum-palladium or copper-nickel metallogenic trend. Produced data is compared with indicator values of duration of massif formation with account of the fact that for platinum-palladium ore mineralisation with incidentally extracted Ni, Cu, Au, Co, Rh the indicator values of duration of formation are assessed as 2530-2420 million years, at the same time magmatic ore-bearing phases at the Baltic shield have the age of 2490±10 million years, 2470±10 million years, 2450±10 million years, and for the massif with copper-nickel mineralisation with incidentally extracted Co, S, platinum group metals, Se, Te, the indicator values of formation duration are in the range of 2200-1980 million years with the main ore phase, having the age of 1980±3 million years. The conclusion on prospectivity of the tested basite-ultrabasite massif for platinum-palladium or copper-nickel metallogenic trend is made with account of localisation of mineralisation of contact type in the lower series along the cut, mineralisation of rift type - at the border of series-megacycles with replacement of chemical composition of magmas, and mineralisation of offset type - in tectonic abnormalities in the thickness of country rocks. |

Using seismic records from the source of seismic waves - distance earthquakes (at the distance of more than 2°), they establish magnitude of a future earthquake, and on the basis of reaction of a water-bearing horizon in the hydrogeological well to the effect of lunisolar tides they determine the time slot of the medium-term forecast, the start of short-term forecast, and determine the time of earthquake occurrence. The time of start of the time slot of the medium-term forecast is determined by the time t1 - start of stop of the reaction of water-bearing horizon to the effect of the lunisolar tide, and the time of start of the short-term forecast of the earthquake t2 is set on the basis of time of recovery of the reaction of the water-bearing horizon to the effect of the lunisolar tide.

A sum of local component is defined for all the target reflecting horizons. With that, the local structure is considered to have been prepared for all the target reflecting horizons when the value of sum of local component is larger than zero. For allocated localised structures for each reflecting horizon there calculated is local structure amplitude and local structure surface area.

The level of technology
[0001] In many areas where work well, use sensors monitor various parameters in the well. The sensors down into the well bore, and the values of the parameters passed to the upstairs independent ground Boxing for data collection. Then the data is output to the screen and/or processed in order to observe and assess certain aspects of well system. However, independent ground Boxing for data collection and architecture associated systems can generate significant complexity and increase the cost.
Summary of the invention

In some cases electric output at the mouth of the well is used for wireless data transfer in ground data gateway.

[0007] figure 4 shows a schematic representation of the wellhead and integrated electric output at the mouth of the well, which has a wireless connection with another example the implementation of the terrestrial gateway data, according to an alternative embodiment of the present invention.
Detailed description of the invention
[0008] In the following description outlines many of the details that contribute to understanding of the essence of the present invention. However, the specialists in this the area will be clear that this invention can be done without using these details, and that in the described examples of the implementation, you can make many changes or expose these examples of different modifications.
[0009] the Present invention, in General, refers to system to monitor one or more of the required parameters in the well. According to one embodiment, described below, observation system is a system of continuous monitoring, which has greatly simplified architecture on the surface. In the mouth of the well integrated electrical output, capable of performing the functions performed otherwise independent surface box for collecting data. For example, an electric outlet in the mouth of the well can be a wireless conclusion in the mouth of the well, which can do without wires between the mouth of the well and a separate system for data collection. In addition, an electric outlet in the wellhead can be integrated with a power source that provides power downhole monitoring. Simplified architecture of this system facilitates the installation and integration with surface system, providing a significant reduction of the value in compared with traditional wired systems.
[0010] figure 1 shows an example of a typical well systems 20, containing the mouth of 22 wells, located above the well 24, with the barrel 26 wells. In addition, at the mouth of 22 wells integrated electric conclusion 28, so you can pass characterize well the data in the desired external system 30, such as terrestrial gateway data. For example, electric conclusion 28 may represent a wireless module 32 intended for establishing a wireless connection to the gateway 30 data. In an alternate embodiment, the module 32 can take the form of a plug-in module (or contains a built-in plug-in module to allow it to temporarily or permanently connected to the wire to transmit data to the external system.
[0011] In the example implementation borehole system also contains 20 borehole system 34 tracking intended to identify and/or monitor one or more of downhole parameters. Borehole system 34 tracking transfers data up into electrical output 28 at the mouth of the well. For example, borehole system 34 tracking contains the sensor 36, such as a measuring instrument. Depending on the specific example of the implementation of the sensor 34 can be a pressure gauge, thermometer or device intended for the joint determination of pressure and/or temperature in the required position along the trunk 26 wells. Some examples of the implementation of the gauge 36 put on the outside of pipes 38, such as the outside of the pump-compressor columns, pressure pipe or casing string lowered into the borehole. In addition, borehole system 34 observations can be represented as a set of sensors is provided with one or more additional sensors 40. According to one embodiment of one or several sensors 36, 40 may be on pipes 38, in this example, the implementation of the outside of the casing, so that you can track the formation and/or fluids. Other sensors can be inside a pipe 38 or in another appropriate place in the well.
[0012] As shown in the figure, borehole system 34 observations are connected with an electric output 28 at the wellhead cable 42. Cable 42 is a measuring cable can transmit data at the mouth of 22 wells on the surface. However, 42 cable can be used to supply energy in a borehole system 34 tracking to ensure food downhole sensors, if they do not have their own power source, for example, as well battery. In this example, the cable 42 is a permanent cable, passing between the electrical output 28 at the wellhead and downhole system 34 tracking. The 42 cable can be connected to one sensor or several sensors, such as sensors 36, 40.
[0013] figure 2 shows an example of electrical output 28 at the mouth of the well. In this example, electrical conclusion 28 at the mouth of the well has considerable ability to process the data and integrated into the mouth of 22 wells. For example, electric conclusion 28 at the mouth of the well can be a borehole system 44 telemetry data collection, such as downhole telemetry system collecting data from the sensors connected to the borehole system 34 observations. System 44 telemetry data collection can be connected to the borehole system 34 observations through the line 46 of data transmission in cable 42. Data on downhole parameters passed from the borehole system 34 observations are loaded in the system 44 telemetry data collection and distributed by it.
[0014] Integrated electric conclusion 28 at the wellhead can also include command module 48-situ observing systems to signal control system 34 observations. Conclusion 28 at the wellhead can also include 50 module for data storage, which works in conjunction with the Central processor 52 (CPU), such as the microprocessor. Borehole system 44 telemetry data collection and the command module 48 may also be associated with the processor 52, in order to permit the accumulation, processing, transformation and/or analysis of data from downhole systems 34 monitoring and aimed it at her. CPU 32 can also be associated with a wireless module 32, in order to facilitate wireless data transfer to the external system 30, such as the gateway data.
[0015] In some cases electric conclusion 28 at the wellhead can also include the source of 54 power, used for power supply in borehole system 34 observations. For example, the source of 54 power supply is connected to one or more sensors 36, 40 through the line 56 power, which may be located inside the cable 42. Depending on the destination the source of 54 supply may be in a different location inside the barrel 22 wells or near the trunk of 22 wells. For example, the source of 54 power can be a battery or solar panel.
[0016] In the example implementation conclusion 28 at the wellhead also includes panel 58 registration of indications of sensors to display data about parameters of wells and/or to enter data relevant to the monitoring of parameters of a well. For example, the panel 58 registration sensors uses the GUI 60 of the user or other suitable interface, to facilitate the display and/or data input. In the example shown in figure 2, electric conclusion 28 at the wellhead also contains flameproof enclosure 62, designed in accordance with applicable industry standards for specific areas of use. Similarly, between the mouth of 22 wells and environment on the surface can be properly installed safety barrier 64 in accordance with industry standards for specific areas of use.
[0018] In another example, implementation of the mouth of 22 wells and integrated electric conclusion 28 connected wireless communication with the external system 30, including the gateway 70 data global system for mobile communications (GSM). In this example, the implementation of the gateway 70 data global system for mobile communications is used to transfer data from the output 28 at the wellhead on the potentially significant distances by means of data transmission systems, such as retransmission system 72 or satellite system 74. Data can be transferred to a staging web server 76, used to collect data on the parameters of wells and to ensure the availability of these data for one or more computers 78, for example, through the interface 80, based on Internet technologies. Wireless gateway can have its own power source such as a battery, solar panel, or other suitable power source, or can use a local power source, if available.
[0019] Design all well systems 20, including design mouth 22 wells and integrated electrical output 28 may vary in accordance with the use of downhole monitoring and environment. For example, based on telemetry and carrier requirements in the borehole 24 you can only have one sensor. In some cases, you can use the multi-point system. In addition, one or more sensors, such as sensors 36, 40, can be a pressure sensors, temperature sensors or other types of sensors developed for production and diagnostics of tanks. For example, the sensors can be a ultrasonic sensors, acoustic sensors, pH-meters, Delta-manometers, resistive sensors, capacitive sensors and other sensors or a combination thereof, if necessary, for specific applications.
[0020] In many cases it is desirable to use the sensors are designed for low energy consumption to maximize battery life. As described above, some examples of electrical output 28 at the mouth of the well contain source 54 power, such as the battery, designed to increase the service life of well system 34 observations. For example, the source of 54 power can contain removable batteries or solar panel, integrated with the conclusion 28 at the mouth of the well.
[0021] in Addition, the relationship between the electrical output 28 at the mouth of the well and the external system 30, for example gateway data can be accessed by different methods. In one example of the implementation of wireless communication can be a WI-FI network for local data. In another case, the wireless module 32 electrical output 28 at the wellhead can include GSM module is directly connected to the GSM antenna, and does not need to intermediate gateway data. In addition, the wireless module 32 can be used to pass additional data to the external system. For example, one of the sensors 36, 40 can be located on the surface, in order to carry out measurements at the level of the wellhead, and these data can be sent in the required data gateway.
[0022] Borehole system 20 allows you to create a monitoring system that needs no surface wiring by using a very simple surface architecture. Therefore, the reduction of the cost is related to hardware, and installation, which can be performed faster. In some cases, you can do without certain systems of permanent surface data collection/transfer due to the ability of an electric output 28 in the wellhead to collect data offline. In this example, the implementation of data unloaded from electrical output 28 at the wellhead as necessary, for example, on a periodic basis.
[0023] Accordingly, borehole system 20 observations may take many configurations for use in downhole systems of different types and in different conditions. The configuration of the wellhead, downhole equipment, configuration, monitoring systems and equipment for data collection can be adjusted depending on the destination. In addition, data can be collected and stored in the wellhead for their periodic discharge; or the data on the controlled parameters of the well, you can selectively or automatically be submitted to an external device, for example, using a wireless connection. In addition, this method can be used in wells of different type, including in oil and gas wells, geothermal wells and boreholes.
[0024] Although described in detail just a few examples of the implementation of the present invention, specialists in this area will be clear, what changes can be made without significant deviations from the essence of this invention. Such changes are not beyond the scope of this invention, the amount of which is defined in the above formula.
