SPEED DIFFERENTIAL rodless submersible ELECTRIC PLANT FOR JOINTLY-separate operation of several reservoirs in deep and ultradeep high-producing wells with low reservoir pressure

摘要

The claimed invention relates to the oil industry, the technique of oil production from high-producing deep and ultradeep wells with low reservoir pressure.;This object is achieved by the fact that the proposed speed differential immersion rodless electric-installation for co-Razdelna operation of several reservoirs in the high-producing deep and ultradeep wells with low reservoir pressure, comprising an upper pump module-section with differential attachment of the dispersant with the receiving channels, engine with hydraulic, centralizer-screen TV, a pressure pipe with check valve and thickened sleeve switchblade channels, lower module-section pump with differential attachment of the dispersant with the receiving channels, engine with hydraulic, centering-screen TV, a pressure pipe with a check valve, the average unit-section pump differential attachment of the dispersant with the receiving channels, engine with hydraulic, centering-screen TV, a pressure pipe with check valve and thickened sleeve switchblade channels, equipped with a common power cable with cable glands for connection to each submersible motor, with each centering screen is designed as a steel disc with rounded edges and is provided with elastically deformable sleeves, fixed with its two sides and having a diameter larger than the disc diameter is 20-30 mm, and screwed onto threaded transport tube and secured with clamp couplings on both sides having a rubber cuff belt attachment points to the transport tube and the rings evenly spaced along the circumference of the cuff.
