BUILDING METHOD OF SEISMIC DEPTH SECTION

FIELD: mining. ^ SUBSTANCE: for obtaining the image of seismic depth section, each displayed point (DP) is applied in series to the section along columns and/or lines with the specified pitch along axes of coordinates as a result of review of wave field on n seismograms recorded with multifold profiling method. Review is performed by searching the signals of seismic boundaries possibly crossing/containing DP and belonging to one of q specified aspects of the object (seismic model). For each aspect of the object at the specified velocity section on seismograms there built are q virtual hodographs of the wave of the specified type in compliance with routes of ray path from n impact stations (IS) considering the specified configuration of the object boundaries. There obtained are m marker pips of arrival time of rays of secondary waves possibly outgoing from DP and the sequence adjoining the DP from m points along the boundary. After that, before and after marker pips of arrival times of rays along each hodograph there performed is pseudo-inphase accumulation per ü (usually ü
