FIELD: mining industry.
SUBSTANCE: method includes feeding of compound for selective water isolation, after its pumping hydrophobic liquid or gas are additionally pumped for pressing said compound from face into bed for distance, equal to radius of formed screen, while said compound will take on a form of cover, lower portion of which during contact with water become impenetrable for liquid or gas coming after compound, and upper portion is carried into well during its launch.
EFFECT: higher efficiency.
