FIELD: oil extractive industry.
SUBSTANCE: method includes cutting off of watered portion of productive bed from upper well hollow. Well filter on tubing pipes is lowered. Gas influx is caused. According to invention cross-section of watered portion of productive bed is provided with packer without supporting by pit-face with direction opposite to line of gas-water contact in such a way, that portion of its packing element is placed above the line of gas-water contact. Unpacking is performed by excessive hydraulic pressure in packer hollow.
EFFECT: longer operation of watered productive beds.
