METHOD FOR SEISMIC PROSPECTING Russian patent published in 2000 - IPC

FIELD: seismic prospecting of medium, in particular, methods for detection and localization of various objects and heterogeneities in strata, differing in their properties from the surroundings. SUBSTANCE: a seismic radiator-seismic receiver pair is installed on the area above the surroundings section under prospecting in the first of the preset points, a radiation signal is applied to the seismic radiator once or several times, the accumulated signals re-emitted by the surroundings heterogeneities are received, accumulated and recorded. After that the radiator/receiver sounding pair is displaced to the next preset point of observation, and the procedure of signal radiation and reception is successively repeated in all the preset points of the observation area. The obtained multi-channel seismogram is subjected to optimum filtration, and then the energy of the signals re-emitted from each node of the survey grid inside the surroundings is calculated with the aid of it, and presence of heterogeneities and their configuration are judged by the results of processing of the obtained data. EFFECT: enhanced resolving power and reliability of detection.
