Zusammenfassung:	FIELD: oil and gas industry, particularly pressure testing equipment adapted to determine fluid influx in well string during well repair, isolation and survey. ^ SUBSTANCE: device comprises hollow body with radial channels, sealing member with upper and lower flanges, sliding bush, cone with slips and electric drive. The electric drive is arranged inside the body and includes screw couple, pusher and control-rod. The control rod has destructible split pin and washer. The device also has pump, through orifices made in rod, pressure transducer and double-sided packer provided with independent manometer located under the packer. Pressure transducer has electric circuit adapted to transmit information to control panel. ^ EFFECT: increased efficiency of determination of well string connection air-tightness during hydrostatic pressure reduction. ^ 4 dwg
