STATION FOR TRANSFER AND SEPARATION OF MULTIPHASE MIX Russian patent published in 2015 - IPC F17D1/00 

FIELD: oil and gas industry.

SUBSTANCE: station contains input pipeline, the unit for deemulsifier dosing, at least one borehole pump unit, at least one water-jet pump passive input and active input, a separating vessel, a tubular separator with main outputs and emergency outputs, the first pump, the first drain vessel, the first metering unit, the second metering unit, the second drain vessel, the second pump, sewage vessel, the third pump, output pressure piping, gates, return valves, safety valves. The water-jet pump represents an ejector including a nozzle, a mixing chamber and diffuser. The borehole pump unit represents a sump equipped with a pipe and blind at its lower end and wellhead equipment at the upper end. In the above pipe there is a tubing pipe connected to the wellhead equipment. Tubular annulus is the input to the borehole pump unit. In the lower end of the sump there is a submersible motor with an electric-centrifugal pump installed over it. The latter is fixed at the tubing pipe, which upper end is connected to the wellhead equipment. Inner space of the tubing pipe is the output of the borehole pump unit.

EFFECT: higher reliability and longer life.
