SEISMIC ELECTRIC DOWNHOLE SUBMERSIBLE DEVICE Russian patent published in 2019 - IPC G01V1/52 G01V1/40 G01V3/18 G01V11/00 

FIELD: oil industry.

SUBSTANCE: invention relates to the oil industry and can be used primarily to improve the efficiency of monitoring the development of fine deposits of ultraviscous oil or bitumen by methods of thermal, chemical and mechanical action on the reservoir bed. Disclosed is a seismoelectric downhole submersible device comprising electric and seismic exploration modules arranged in a single housing in isolation from each other. Electric module is connected to one core of geophysical cable, and seismic exploration module is connected to two isolated from each other cores of geophysical cable. Seismic exploration module is a plastic pipe into which three seismic receivers are vertically mounted and interconnected in parallel. Note here that said plastic pipe is filled with heat-resistant epoxy resin to seal and protect seismic receivers. Plastic pipe is placed in a steel pipe which is connected to the electric module by means of electric welding. In lower part of steel pipe there is an insulator. Electric module represents a metal housing of a seismoelectric submersible device, which serves as a submersible electrode during electrical exploration operations. Inner part of electric module represents clean of isolation end of geophysical cable, twisted into spiral, installed in device head and filled with mixture of tin and lead with possibility of providing better contact with walls of device and increasing weight of device.

EFFECT: technical result is simplification of design, high reliability and high technological effectiveness at specified thermobaric conditions.
