FIELD: oil and gas production industry. SUBSTANCE: this relates to materials used for isolation of water inflow to operating oil, gas, and gas-condensate wells. Plugging material includes binding component and modified by surface-active substance hydrocarbon liquid. Used in function of binding component is gypsum-alumina cement at following proportion of components, mas. %: gypsum-alumina cement 55-65, hydrocarbon liquid modified by surface-active substance - the balance. Application of aforesaid plugging material ensures shorter setting period of plugging solution and reduced water-permeability of core samples treated by plugging material. EFFECT: higher efficiency. 1 tbl
