MARINE ELECTRICAL EXPLORATION DEVICE AND PROCESS OF ELECTRICAL EXPLORATION ON RUN Russian patent published in 2008 - IPC G01V3/02 G01V11/00 

FIELD: physics; geophysics.

SUBSTANCE: current pulse is excited in the medium under investigation, and parameters of its induced polarisation are defined. Geoelectric section is generated to make a conclusion about the presence of hydrocarbon fields on the basis of abnormal manifestations of induced polarisation parameters. At that, electromagnetic and seismic waves are excited simultaneously or with a time shift. To excite the said waves unipolar rectangular impulses of direct current are generated, their absolute and relative duration depending on parameters of medium under investigation. In the beginning of timing pulse electric field is measured simultaneously at measuring probe groups of two detector lines towed at different depth. Besides, detector line depth and hydroacoustic pressure of seismic source are measured. Also a device is offered, which includes pulse generator, capacitor charging unit, power generator, bank of capacitors, switchboard, seismic emitter, transmitter/receiver line, receiver line, multi-channel gauge, echo-sounder, GPS satellite navigation receiver, signal processor.

EFFECT: higher reliability of research results.
