WELL COMPLETION METHOD Russian patent published in 2018 - IPC E21B43/25 E21B43/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the completion of oil and gas wells. Method includes the run in of an electric centrifugal pump unit and a cable connecting the unit to the control station, creating draw-down pressure and lifting the killing fluid from the productive formation. Unit includes a submersible electric motor with hydroprotection, a multi-stage pump having a flow hole in the upper part and a lower input module. Inverted pump is used as the electric centrifugal pump. Run in of the unit is carried out in a tubing string pre-arranged in the well on a load bearing cable mounted in a load bearing sleeve. At the lower end of the tubing string, a sealing assembly is installed. Load bearing cable is connected through wellhead equipment to the control station. Above the electric motor, a telemetry unit is placed, which is connected to the load bearing sleeve. For protection during the run in, the unit along the entire length is supplied with centralizers.

EFFECT: method makes it possible to increase the efficiency of well completion by eliminating leakage between the input module and the pump flow holes.
