METHOD OF SEISMIC PROSPECTING Russian patent published in 1995 - IPC

FIELD: geophysical prospecting. SUBSTANCE: method of seismic prospecting provides for synchronous emission into geological medium of longitudinal waves P and waves SH lateral to horizontal polarization and for undestorting registration of each of medium by means of symmetric four-projection geophones which sensors are uniformly distributed in azimuth and are inclined at angle of 45 deg to horizontal line. Emission and reception of seismic waves conducted in this way create favorable conditions for use of procedure of subtraction of wave fields to divide observed superposition wave field into three linear-polarized (waves P, SV and SH) and summary nonlinear-polarized physical components. As a result there appears possibility to study geological section both with separate seismic waves of various types and with their combination on the whole. EFFECT: expanded prospecting capabilities of method. 5 dwg
