PLANT FOR SIMULTANEOUS-SEPARATE EXTRACTION OF HYDROCARBONS FROM THREE BEDS Russian patent published in 2016 - IPC E21B43/14 

FIELD: oil and gas industry.

SUBSTANCE: invention can be used for oil extraction from three beds using one well. Installation consists of upper packer 5 installed between beds of upper 2 and middle 3 levels, and lower packer 6 installed between beds of middle 3 and bottom 4 levels. Between the packers near the bed of medium level 3 there is installed lower electric centrifugal pump 9, inlet module 10 of which is connected to pump-compressor pipes 11 of lower packer, and output module (not shown) - to upper packer 5. Near the bed of upper level 2 there is installed upper electric centrifugal pump 12. Both pumps are coaxially connected by double-sided submersible electric motor 14 arranged under upper pump 12 and fitted on common for both pumps shaft 13, which passes through upper packer 5. In upper packer 5 there are holes 20 for passage of fluid from formations of middle 3 and bottom 4 levels into the space above the packer.
