PROCESS OF SPATIAL SEISMIC PROSPECTING Russian patent published in 1996 - IPC

FIELD: geology. SUBSTANCE: process includes excitation of seismic field by sources positioned on land surface and registration of oscillations with two arrangements of geophones. (One of them is placed on land surface, the other one - at internal points of medium in one or several boreholes). Joint processing of land and borehole observations and plotting of spatial model of examined structure on the basis of processing results. Excitation sources of seismic field and points of land arrangement of geophones are positioned in compliance with scheme of profile or area seismic prospecting standard for given area with the use of method of common depth point. Registration of oscillations is conducted simultaneously at borehole and land arrangements of geophones from common excitation points. In this case depth of submergence of arrangement of geophones in boreholes is changed depending on distance to excitation source. Simultaneous registration of seismic field on borehole and land arrangements of geophones from common excitation points makes it possible to identify positively waves registered by both arrangements, to enhance accuracy and authenticity of geological structures. EFFECT: enhanced accuracy and authenticity of identification geological structures. 1 dwg
