FIELD: oil and gas industry.
SUBSTANCE: system includes two packers installed on tubing, one of which is located above lower formation and the other one above upper formation, as well as electric centrifugal pump installed in lower part of the pipe. Both packers are provided with electric cable entry. Packer that is located above lower formation has the possibility of being installed mechanically in the well by axial movement of tubing. Packer that is located above upper formation has the possibility of being installed in the well by means of axial unloading of tubing weight and equipped with hydraulic anchor with cable entry.
EFFECT: simpler well operating process in the part of possible reduction of scope of lifting and lowering operations, reduction of down time, as well as possible involvement of a new formation in the operation.
