FIELD: oil and gas production.
SUBSTANCE: method for oil production includes dispersion of reservoir fluid with gas and subsequent supply of gas-liquid mixture to intake of electric centrifugal pump. According to invention, upper reservoirs and lower reservoirs and/or interval of well leakiness are isolated by installation of at least one packer over electric centrifugal pump. Gas is separated with simultaneous ejection of gas from below-packer zone into lifting pipes over electric centrifugal pump. Dispersion of reservoir fluid is done with reservoir and below-packet gas, and it is executed in below-packer zone until uniform homogenous gas-liquid mixture is produced, with its further supply to intake of electric centrifugal pump and pumping of uniform homogenous gas-liquid mixture to surface.
EFFECT: increased efficiency of well operation.
