FIELD: engines and pumps.
SUBSTANCE: invention relates to pumping stations for intra-field single-pipe transportation of oil-and-gas production of oil wells to a central point of oil collection and treatment. Disclosed is a multiphase mixture pumping station consisting of a multiphase pump, a centrifugal-vortex separator with an intake device in the paraxial region, a collector and a diaphragm. During operation of the station, the water-gas-oil mixture is supplied to the multiphase pump after mixing in the header with oil supplied through the diaphragm from the intake device. From the pump, the compressed working medium is supplied via a pressure line to a separator, from which gas and an oil-water mixture containing mechanical impurities are removed, mixed and removed from the station.
EFFECT: technical result is simplification, reduced metal consumption and increased reliability of multiphase mixture pumping station operation.
