FIELD: oil and gas industry.
SUBSTANCE: device contains electric drive installed vertically under production pump and its output shaft is connected to drum placed vertically. Logging tool is fixed at the lower end of logging cable that transfers data of logging tool to the well head, supplies power to electric drive and laid at the drum by cable worker. At the device housing, at limit points of cable worker movement the upper and lower limit switches are installed to reverse direction of electric drive rotation.
EFFECT: increasing survey interval, decreasing outside diameter of device, improving operational reliability of device.
