SEISMIC PROCESS OF PROSPECTING WITH USE OF REFLECTED LATERAL WAVES

摘要

geophysical prospecting, processing of data obtained through azimuthal-anisotropic layers of ground varying in thickness. SUBSTANCE: process includes following operations: removal of layers where changes of polarization are specified with the aid of application of static shift to components matched with direction of polarization of slow lateral wave and with the aid of application of half of static shift to components which are not matched neither with direction of polarization of slow lateral wave, nor with direction of polarization of fast lateral wave; obtainment of magnitude of amplitude of mantle of path of fast polarization; turn of data set approximately through 45 degrees aside from key direction, obtainment of magnitude of amplitude of mantle along one of mixed directionally polarized paths as minimum; obtainment of relation of amplitude of mantle of path of fast polarization to amplitude of mantle of mixed directionally polarized path. EFFECT: improved functional reliability of process. 7 cl, 18 dwg
