GARIPOV METHOD OF SIMULTANEOUS SEPARATE PRODUCTION OF HYDROCARBONS AND EQUIPMENT FOR ITS IMPLEMENTATION Russian patent published in 2013 - IPC E21B43/14 

FIELD: oil and gas industry.

SUBSTANCE: method includes running-in of submersible pump at tubing string, installation of one or several packers upwards submersible pump, installation and operation of bypass system with regulator and insert though which formation fluid can pass, extraction of formation fluid can be made and change in mode of formation fluid extraction can be performed. At that regulator is installed so that it can move in space between insert and packer mandrel and/or tubing string. Axial channel of the insert is disconnected hermetically from space between the insert and mandrel and/or tubing. Change in modes of formation fluid extraction is made at continuous operation of oil-well equipment. Extraction of formation fluid is made through axial channel of the insert with subsequent delivery through tubing string.

EFFECT: increasing efficiency of formation fluid production due to reduction of hydraulic loss by direct upward flow of formation fluid from submersible pump and providing continuous operation of the equipment at change in mode of formation fluid extraction.
