FIELD: mining industry. SUBSTANCE: a part of producing wells 1, in case of detection of flooding symptoms, located over circumference near the gas-water contact 4, is changed for injection ones. Injected through wells 1 is chemical reagent to form barrier zone 2 with pore saturation ensuring its immobility. Sediment formed in contact of chemical reagent with formation water coming to the pool hampers flows of formation water, preserving in this way the operating wells 3 in dry zone. EFFECT: higher efficiency. 2 cl, 1 dwg
