METHOD FOR SEISMIC SURVEY

摘要

Method for seismic survey includes excitation of elastic vibrations and reception of seismic signals at equal distance from point of excitation with displacement of arrangement in profile with separation that does not exceed distance between the point of excitation and point of reception. For each position of point of excitation seismic signals are received in three points one of which is placed at line of displacement of excitation point and two others – symmetrically with respect to point of excitation at line normal to direction of its displacement, at that the distance between the point of excitation and equidistant from it point of reception one sets not smaller than value of three values of length of refracted wave number conditions of investigation, and registered refracted waves are normalized by energy of signal of registered by the fourth point of reception that is installed in direct vicinity from excitation point.
