FIELD: mining.
SUBSTANCE: according to the method the well is put into operation, the borehole production is extracted by means of an electric centrifugal pump and the repair-and-renewal operations are performed simultaneously with carrying out tripping operations, well washing and gaging, the downhole equipment is mounted using tightly screwed up pump and compressor pipes of the electric centrifugal pump and a packer, tubing string, and decolmatation. During the well development on its surface the downhole equipment is installed. The power cable end is passed through details of anchor and separating devices of the packer and tightly connected to the variable frequency drive of the electric centrifugal pump. During the installation the electric centrifugal pump fitted with the input module and the unit of sensors of telemetric system of monitoring of borehole product parameters, stop and flushing valve and knock-off the valves which are tightly screwed together by tubings are lowered into the production string. The submersible downhole equipment is screwed together with a trunk of a packer on which mount the anchor and separating devices, and in cable input of a packer pressurize a power cable. From above the packer is screwed together tightly with the second knock-off valve which is screwed together a tubing with the coupling of the reference branch pipe. The latter using the coupling on another its end is screwed together with the tubing string to the end of which through the coupling the casing swage is screwed in. Lowering is continued until achievement by the packer of an interval of segregation of tubular annulus with fixation of the packer sitting depth being adjusted using the reference point. The tubing string with the downhole equipment is lifted on height equal to length of the established casing swage which replace with a branch pipe of the respective length. Using the anchor device the packer is fixed in the production string and leakiness is eliminated by tensioning of the tubing string to a certain load of the packer using the dynamometer. The tubing string through the casing swage is connected tightly to the faceplate and fixed on the production string flange in the wellhead. After that by gradual increase of frequency of rotation of the variable frequency drive of the electric centrifugal pump the well is put into operating mode of operation with monitoring of parameters of the borehole product by means of the telemetric system.
EFFECT: well operation reliability improvement.
