PLANT TO PUMP TWO-PHASE GAS AND FLUID MIXTURE OUT OF WELL

摘要

FIELD: equipment to pump hydrocarbons out of oil well. SUBSTANCE: plant is designed for location in well passing from ground surface to oil-bearing stratum. Plant includes string of rising pipes on which lower end pump is mounted, seal packing placed in well around string and forming camber in lower part of well. Fluid is located in lower part of chamber and gas is contained in its upper part. Hydraulic ejector including rarefaction zone communicating with upper part of chamber is positioned in string. Return valve is installed in string between pump and hydraulic ejector and side hole made between pump and return valve is meant for gas release. Invention is directed at provision for delivery to ground of separate flows of fluid and gas formed at well bottom from two-phase gas and fluid mixture passing to bottom hole from stratum in the form of one flow. EFFECT: delivery to ground of separate flows of fluid and gas. 2 cl, 4 dwg
