FIELD: oil and gas producing industry.
SUBSTANCE: invention is referred to oil and gas producing industry. According to the method in the beginning water-insulating material volume is defined. The water- insulating material is injected in a hole. It is pressed through in a formation. Thus, a water- insulating material is placed in annular space of a bottom-hole zone of the hole, bounded by isopotentials. Pressure on isopotentials makes 0÷1/3 to 1/2 from a total pressure drop between reservoir and bottom-hole magnitudes. Radiuses of isopotentials are counted under the formula.
EFFECT: it provides efficiency upgrading of water inflow isolation.
