| Ամփոփում: | Заглавие с экрана At the present time amplitude and reflected energy information of the waves is widely used in processing and interpretation of seismic wave fields. The phase-frequency response characteristics of the reflected waves are not so widely used. Meanwhile, the phase of seismic signals, or rather the complex law of variation of their phase spectra, contains important information on the location of reflectors, the type of velocity configuration, the absorptive and dispersive properties of the layered subsurface. The phase-frequency algorithms for seismic data tracking can be synthesized based thereon allowing, under condition of prior uncertainty with respect to the wave shape on test, detection and release of the signals against high-amplitude noise and production of the reliable estimates of their parameters. Using the phase-frequency response characteristics of the reflected waves is also useful in problem solving of the geologic profile forecast, including the prediction of sedimentation mass oil and gas occurrence. The present article briefly discusses the possibility of using the earlier proposed phase-frequency algorithms of the seismic response analysis in processing and interpretation of the seismic wave fields. Some examples are given to prove the efficiency thereof for problem solving of the geologic profile forecast in the borehole environment.
