FIELD: oil and gas industry.
SUBSTANCE: in the probe case there is an electric drive, seismic vibration sensors, a pressure piston, the upper and lower slave pistons with a compensating piston placed in the upper one. Space between the pressure and upper pistons as well as between the upper and lower slave pistons is filled with incompressible liquid. The probe case is equipped with holding arms spread along its length.
EFFECT: simplification of the probe structure, increase in safety of borehole measurements.
