EQUIPMENT FOR MULTI-RESERVOIR WELL SUMULTANIOUS-SEPARATE RECEARCH AND PRODUCTION WITH ELECTIRCAL SUBMERSIBLE PUMP (VERSIONS) Russian patent published in 2010 - IPC E21B43/12 E21B47/12 

FIELD: oil-and-gas industry.

SUBSTANCE: installation includes well equipping with a one-parker or multi-parker assembly on reservoirs depth, with ability to descent a tubing string with an electrical submersible pump with or without a shell into the well, and with at least one control valve. The multi-parker assembly equipped with connected or disconnected between each other, at least two landing units, located over the top parker and between parkers accordingly. The control valve equipped with an external separator and an internal tail with a sealing device. The electrical submersible pump descending over the multi-parker assembly executes with ability of a simultaneously sealed connection, of the sealing element to the landing units between parkers, also the external separator to the landing unit over the top parker. The control valve consists of a case with at least two hydraulically connected with each other non-axial and one axial pass through channels, inside of which located shut off element of a electromechanical, electromagnetic or hydraulic action, such as a piston, a plunger, a shut off valve or a rotary disk, installed with ability to move for instances to the middle, or up and down, or rotation from one position to another, and signal or impulse control from the wellhead or automatic control based on the fluid parametres, transmission through a cable or tube, or a tubing string or a medium. At that at one of its position, all of the pass through channels, partly or in total, connected to the electrical submersible pump inlet and to the well reservoirs as well, for the simultaneous fluid production, at another position - cutting of the fluid, at least from one of the reservoirs by shutting off inlet or outlet of the corresponding non-axial channel for characteristics and regime research of at least one of the reservoirs, which is still open. In one-parker assembly version, the control valve connected to the shell form the top, and with parker-from the bottom.

EFFECT: well production installation efficiency and reliability increase.
