METHOD OF PUMPING OIL PRODUCTION WITH HIGH GAS FACTOR Russian patent published in 2017 - IPC E21B43/00 

FIELD: oil and gas industry.

SUBSTANCE: lateral hole is drilled below the dynamic fluid level in the mother bore by the method. The slaughter of the mother bore is cemented and equipment is lowered into it. The shank and the deep pump are lowered into the mother bore below the lateral hole insert. They are located above the lateral hole hookup. The annular space of the well is connected to the upper part of the head tank and the flow header located at the wellhead. The lower part of the head tanks is connected to a pump, the receiving part of which is connected to the supply container for the working fluid. The pumping out of the accumulating gas from the annular space is periodically performed by means of a pump that is turned on to supply the working fluid to the delivery tank with gas in the cycle of its injection into the flow header and that is turned off to drain the working fluid from the delivery tank into the delivery tank feeding in the cycle of gas supply from the annular space.

EFFECT: increased efficiency of the separated gas selection from the annular space of the well and its injection into the header.
