SEISMIC PROSPECTING METHOD Russian patent published in 1994 - IPC

FIELD: seismic inspecting. SUBSTANCE: seismic waves artificial sources are placed outside of investigating zone and seismic waves receivers are placed in internal points of zone under investigating so its positioning being on line perpendicular to refraction wave travelling direction. Received seismic recordings are recalculated to region surface and transformed to time-depending cutting line of space under investigating taking into account travelling velocity of set type of wave. EFFECT: more effective geological stricture prospecting for separate regions. 1 tb, 1 dwg
