METHOD FOR LIMITING WATER INFLUX IN PRODUCTION WELL

摘要

FIELD: oil and gas industry.SUBSTANCE: method involves descending of hydraulic jet perforator at specified depth, descending of tubing string with packer into the well, pumping of fracturing fluid and sand-carrier with restraining material into tubing string, process exposure, well putting into operation. According to invention the data of geological-geophysical researches help to determine the character of formation saturation and position of gas-water contact. Hydraulic jet perforator is descended at 5-10 m below gas-water contact. There performed is a hydraulic fracturing of the formation in interval opened by hydraulic jet perforator. Water saturated part of the formation is developed via tubing string and gas saturated part of the formation - via annular space. The restraint of water influx into the well is adjusted by water withdrawal through tubing string.EFFECT: limitation of water influx into operation well.1 dwg
