PLANT FOR DUAL OPERATION OF MULTIPLE-ZONE WELL WITH TELEMETRY SYSTEM Russian patent published in 2014 - IPC E21B43/14 E21B47/12 

Abstract RU 2512228 C1

FIELD: oil and gas industry.

SUBSTANCE: plant contains in the casing pipe a pipe string, electric pump, power cable and device for dual strata operation made in a housing consisting of adjustment units and production rate measurement unit that contain controlling valves and instruments and meters. The housing consists of pipes equipped with packers and connected by sleeves for cross-flow fluids. Controlling valves are made in a cage with installed electrically-actuated needle valve interacting with crossover seat. In cage walls there are windows made at both sides of crossover seat. Instruments and meters are located higher and/or lower than controlling valves; they are interconnected by a logging cable laid in the channel made in the cage wall. Adjustment units and production rate measurement units are connected to the power cable by logging cable, TMC adapter installed at the end-face of electric pump and cable socket, which pin is fixed at a mounting flange with openings installed at the end-face of the housing and a contact pair socket placed in the centring skid fixed at the end-face of electric pump.

EFFECT: increasing efficiency of dual operation of the well at optimum regulation of phase composition and metering of fluids from strata on real-time basis.
