SEISMIC SURVEYING BY MEANS OF PULSE SURFACE SOURCES Russian patent published in 1994 - IPC

FIELD: seismic survey. SUBSTANCE: sonic pulses and seismic oscillations are excited simultaneously by a group of surface sources, disposed onto the profile line. Seismic oscillations are received by seismic detectors and sonic pulses are received by microphone. Oscillations and pulses are detected and processed simultaneously by seismic station. Microphone is located onto the profile line. Range between the sources is determined from the relation δ_x≥ (3-6)V_s·S_t, where V_s is speed of sound in atmosphere, S_t is standard root-mean-square deviation of moments of sources operation. EFFECT: simplified production process; reduced labour input. 4 cl, 2 dwg
