Abstract.

The object of research in this article is a system for receiving seismic signals in a well, carried out by the method of vertical seismic profiling. The subject of the research is data processing methods from a bunch of downhole modules obtained by vertical seismic profiling in software for controlling and controlling a hardware-methodical complex for receiving seismic signals in a well. The authors consider in detail such aspects of the topic as the complexity and speed of seismic data processing algorithms obtained from borehole and surface modules. The authors use the following scientific methods, namely: mutual correlation in the time and frequency domains. The novelty of the results are the conclusions that in the considered complex the correlation in the spectral region provides a gain in the number of operations on the correlation in the time domain. The calculation in the time domain gives a more accurate result, since the Fourier transform on the final sample gives distortions even when using window functions. To obtain a correlogram of the same length in the calculation method in the time domain, it is necessary to register and process a larger amount of data than when using the calculation method in the spectral domain.

Keywords: well modules, multi-wave seismic, geophysical data systems, frequency domain, time domain, vertical seismic profiling, hardware-methodical complex, seismic records, vibration seismic, seismic signals
