Resonant scanning geophone // 2635399
FIELD: physics.SUBSTANCE: invention can be used to record mechanical oscillations, in particular high-frequency seismic noise (HFSN), by a resonant method in a wide frequency band. The proposed geophone comprises a body and an elastic element in the form of a metal plate. One end of the plate is clamped into the support installed in the body, and on the other, the inertial mass is reinforced in the form of a coil of a durable light material, for example, a carbon fibre reinforced plastic, with a wire wound from it of heavy material, for example, tungsten. The second coil is installed in the cody, configured to rewind the wire between the coils. The rotation on the coils is transmitted by servo drives from two reversible motor generators mounted in the body, connected to a common electrical circuit with the possibility of coordinated switching them from the engine mode to the generator mode and back. Herewith when the first one is in the engine mode (rewinding mode from the second coil to the first coil), the second one is in the generator mode and vice versa. This prevents the wire from sagging when changing the direction of its rewinding. The rewinding of the wire between the coils leads to a change in the inertial mass and, as a consequence, to a change in the resonant frequency of the system. This provides the ability to scan the operating frequency band. The choice of coil and wire materials from light and heavy materials, respectively, is due to the need to expand the change range of the inertial mass and, thus, to expand the scanned bandwidth. Near the support on the elastic plate, there is a flat sensing element in the form of a bimorph piezoelectric transducer of the rectangular shape. The output signal from the converter is fed to both the recorder and the input of the scanning device, enabling the control of the scanning speed. To ensure a linear dependence of the output signal of the converter on the amplitude of mechanical oscillations of the plate and to increase its long-term strength at the point of connection with the support, the elastic plate at the bimorph attachment point is made in the form of an isosceles trapezium, the larger base of which is clamped into the support. The geometric dimensions of the plate are chosen so that the relation (a+b)d=ac is satisfied, where a is the distance from the fastening point of the inertial mass to the smaller base of the trapezium d, b is the height of the trapezium, c is the greater base of the trapezium.EFFECT: extending the band of recorded frequencies and the accuracy of their identification, ensuring the linearity of the amplitude of the output signal of the converter from the amplitudes of the recorded oscillations, increasing the accuracy of determining the amplitudes.2 cl, 2 dwg

ethod of vibrational seismic survey // 2623655
FIELD: physics.SUBSTANCE: method of vibrational seismic survey based on the excitation and registration of seismic vibrations in the control of a reference signal by a vibration source of oscillations is proposed. According to the claimed solution, the reference signal is divided into intervals that are commensurate with each other in time duration. The duration of an individual interval is two orders of magnitude shorter than the duration of the reference signal. After that, the reference signal intervals are joined together in a new sequence, the place of each of the previously allocated intervals in this sequence being determined from a random number sensor. The new reference signal generated in this way is used as a control signal, when vibrations are emitted by a vibrator, and also for the formation of the correlation functions of the registered seismic records with this reference signal or for the deconvolution of records using an operator calculated from this reference signal. Quasi-random sequence of intervals of the original reference signal for different sources turns out different due to different starting values of the random number generator. Thus, it is possible to operate different sources of vibration simultaneously, for each of which a newly formed reference signal is characterized by a sequence of intervals divided by other newly generated signals, into which the original reference signal is divided. Thus, from seismic records obtained by simultaneous recording of signals emitted by different sources, it is possible, by mutual correlation or deconvolution with a reference signal tied to a specific vibration source, to extract exactly that portion of the record that is recorded from this vibration source. The initial reference signal, from which a new reference signal with a quasi-random sequence of intervals is formed, can be either calculated or recorded inside the medium or in the near-surface zone.EFFECT: improving the quality and efficiency of the vibration seismic surveys.2 cl

ethod of determining the location of the microseismic focus // 2620785
FIELD: physics.SUBSTANCE: according to the claimed method of locating the focus of a microseismic event during the processing of the original microseismic signal, it is decomposed into the detail layers (scales) d(n) with different energy and frequency characteristics. At each of these scales, d(n) is constructed as a straight-line function and, if it is maximized, the arrival time of the longitudinal component of the microseismic signal is found. To each of the original longitudinal and transverse components of the microseismic signal, a discrete wavelet transform is applied, followed by their decomposition into detailed layers (scales) d(n) with different energy and frequency characteristics. At each of these scales d(n), the ratios of the transverse amplitudes to the longitudinal amplitudes are constructed and the arrival time of the transverse component of the microseismic signal is found. The speed of the components of the microseismic signal is determined, on the basis of which the distance to the source of the microseismic event is calculated.EFFECT: reduction of uncertainty in calculating the location of the source of the microseismic event during hydraulic fracturing of the formation.4 cl, 5 dwg
