FIELD: oil and gas industry.SUBSTANCE: invention relates to hydrocarbon production and can be used for extraction of well fluid from two beds using one well. Installation consists of upper and lower electric centrifugal pumps, separated by packer, which drive is carried out by double-sided submersible electric motor located between pumps on one shaft with them above packer. Shaft, which transmits torque to the lower electric centrifugal pump, passes through packer and is centered in it by means of sliding bearings. During operation liquid flows from bottom formation by lower electric centrifugal pump, rise in above-packer space through the flow passage located in the body of the packer. For control of operation and provision of its efficient operation in assembly of installation there are lower and upper measurement units, by means of which there is measurement of temperature, pressure. Fluid flow rate separately in under and above-packer spaces, as well as transmission of obtained data by means of radio signal on a unit for receiving and transmitting information.EFFECT: higher reliability of installation.5 cl, 1 dwg |
