Аннотация:
The main aim of this study is a theoretical and experimental validation of the method based on a recording of the seismoelectrical effect upon excitation of seismic fields by the special non-explosive striker and without an additional source of the electromagnetic field. Signals of seismic and electrical fields were recorded using earthed electric dipoles and seismic receiver with subsequent processing using seismic acquisition system. The frequencies of recorded fields were in the range of 0.1-20 Hz. The observation results of seismoelectrical effect resulted from excitation of the geological section by seismic shocks (a KEM-4 striker) and recording of secondary electrical and seismic fields on the surface by measurements of their cross-correlation function. The activities were performed during July 23-30, 2017 on Bystryansky gas condensate field (Krasnoyarsk Krai, Minusinsk district). The productive deposit was indicated by the maximum coefficient of cross-correlation by three times higher than normal background. 3D maps of the seismoelectrical section were obtained for the first time.
