FIELD: mining.
SUBSTANCE: invention relates to mining and is intended for extraction of high-viscosity oil by two screw pumps simultaneously and separately from different formations of well. Proposed plant comprises frequency-controlled electrically driven screw pump lowered to the well on the flow column, which is located above lower reservoir, equipped with telemetry unit with pressure, temperature and vibration sensors, connected by cable line to control station, packer installed between electrically driven screw pump and upper formation, and rod screw pump with check ball valve in input module, located above upper layer and enclosed in casing, rotor of which is connected by rod with frequency-controlled drive, connected to control station. Rotor rod of rod propeller screw pump is connected to drive shaft of frequency-controlled electric drive closed drive chain of chain transmission of rotation, arranged on production wellhead, wherein cable connecting control station with electric drive screw pump, is passed in well outside casing via cable inlet of packer.
EFFECT: technical result is improvement of operational capabilities of installation with screw pumps at simultaneous and separate extraction of high-viscosity oil from different formations of wells.
