FIELD: oil industry.
SUBSTANCE: group of inventions relates to oil production and can be used for simultaneous-separate extraction of well fluid from two formations of one well. Plant with first version contains deployed in casing pipe on flow column packer with two anchor devices oppositely directed action, centrifugal pump with receiving module and submersible electric drive connected power cable with the control station (CS), tightly passed through wellhead equipment, adjusting electric valve (AEV), which includes shank with cutoff of fluid flow with locking seat, and sensors of telemetry system (TMS), and interfacing unit connected with device taking fluid from lower formation and consisting of telescopically coupled union installed on packer, and nipples, docked to shank, connected to electric drive end. In shank wall are made through holes connecting space above packer with packer and bottom formation. Shank is equipped with centralizer, providing connection of nipple and union. AEV TMS is connected with control panel (CP) by electric communication cable, tightly passed through wellhead equipment. According to second version, proposed plant comprises packer with cable entry and support anchor device, well chamber with flow channel, outside which there is rack, and coupling cross flow of fluid flows, communicating radial channels with upper formation. Well chamber is connected to one side with flow channel to communicate flow channel chamber with flow column, and on other is coupling with at least two eccentric flow channels, connected with packer by above-packer pipe. One of eccentric coupling channels communicates chamber flow channel with pump outlet through shank and branch pipe, conjugated with central channel cross flow coupling and forming together with above-packer pipe and barrel packer coaxial channel, communicating with radial channels cross flow coupling, attached to end of packer and below-packer pipe connected to pump. Other eccentric channel coupling connects the space above and below packer is through shutoff AEV seat, coaxial channel and radial channels cross flow coupling.
EFFECT: technical result consists in simplification of design and higher reliability.
