FIELD: oil and gas industry.
SUBSTANCE: invention relates to the hydrocarbons extraction from small diameter wells using submersible electric centrifugal pumps equipped with a thermal manometric system (TMS). The reservoir fluid lifting unit contains a submersible electric motor with a seal section and a power cord, a pump, a control station with a frequency converter, a tubing and a TMS system with a hydraulic line. TMS is installed over the submersible electric motor and is connected to it via a detachable docking unit. The power supply cable is passed through the TMS. To prevent liquid leakage in case of hydraulic line interruption, the TMC is equipped with a valve.
EFFECT: invention allows to mount equipment on the well, reduce radial dimensions and increase the unit reliability.
