METHOD FOR COMPLETION OF CONSTRUCTION OF PRODUCTION WELL WITH HORIZONTAL END OF WELLBORE Russian patent published in 2020 - IPC E21B43/10 E21B43/26 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil and gas industry, namely, to development of oil, gas and gas condensate fields. Proposed method comprises lowering and fitting of cementless shank-filter into horizontal end of wellbore with disconnecting packers, multi-stage hydraulic fracturing ports and flow regulators. Then, tubing string is lowered with complex of underground equipment to design depth, input of tubing string is made with sealing device into polished receiving socket of packer of shank tail, and coil-tubing unit is installed. Test HFF is performed in the interval from the shoe of the column to the first disconnected packer. Test HFF results in the basic HFF in the given interval. In subsequent intervals HFF is carried out similarly. Number of cycles is equal to the number of the formation fracturing ports. After closing the last port, flow regulators are opened.

EFFECT: higher efficiency of hydrocarbon production due to selective production of HFF, increased area of hydrocarbon influx due to devices of flow regulators and prevention of proppant transport.
