FIELD: oil machine building.
SUBSTANCE: invention relates to installations for intra-field single-pipe transportation of water-and-oil-well well products of oil wells to a central point of oil collection and treatment. Multiphase pumping station consists of multiphase pump, centrifugal-vortex separator, manifold and diaphragm. During operation of multiphase pumping station, water-gas-oil mixture is supplied to multiphase pump after mixing in collector with water-oil mixture, supplied from centrifugal-vortex separator. From the pump, the compressed working medium is fed into the centrifugal-vortex separator via a pressure line, from which gas and water-oil mixture is withdrawn, part of which is supplied to collector through diaphragm, and the other one is mixed with gas and discharged.
EFFECT: simplified and reduced metal consumption of multiphase pumping station.
