INSTALLATION FOR SIMULTANEOUS-SEPARATE OPERATION OF TWO BEDS OF ONE WELL Russian patent published in 2017 - IPC E21B43/14 E21B43/12 

Abstract RU 2617733 C2

FIELD: mining.

SUBSTANCE: invention can be applied for simultaneous-separate operation of two beds. The installation comprises a centrifugal pump with a receiving module and an electric drive, a packer and an adjusting device that allows fluid bypass of one of the banks to mix bank production before rising to the daylight, moved down into the drive tube on the tubing string. In this case, the adjusting device consists of an electric drive fixed to a submersible pump, a telescopic rod and a screw head. The submersible pump is installed above the packer. A shank with a top funnel is hermetically sealed into the packer. A screw bushing is hermetically sealed in the shank. At the same time, the screw head is partially or completely inserted into the screw bushing, regulating the volume of fluid flow from the lower bank to the behind-the-packer space. Regulation of the screw head immersion into the screw bushing is provided by a telescopic rod by means of an electric drive.

EFFECT: increase of simultaneous-separate operation efficiency of two layers of one well due to fluids mixing regulation smoothness of two layers of one well.
