METHOD OF INCREASING OIL RECOVERY OF PRODUCTIVE FORMATION AT SIMULTANEOUS SEPARATE OPERATION Russian patent published in 2019 - IPC E21B43/14 F04D13/12 E21B36/00 

Abstract RU 2704411 C1

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil and gas industry and can be used for simultaneous separate operation of productive strata with pumping units. Proposed method comprises development of two productive strata with one well according to ECP-SRP process scheme. Lower bed is operated by the electric-centrifugal pump in steady-state conditions with constant flow rate. According to the invention, the upper stratum is operated in intermittent mode by a sucker-rod pump, stopping selection for a time required for its warming up due to natural heat energy of formation fluid of the lower stratum and heat produced by the electric-centrifugal pump.

EFFECT: higher efficiency of SSO.
