FIELD: oil extractive industry. ^ SUBSTANCE: method includes force-pumping of sodium silicate into the bed, into the bed at temperature from 100 to 250C powdered crystalline sodium silicate of high dispersiveness having particles size of 10 micrometers and silica module lower than two in form of water suspension in technical water is force-pumped, at following ratio of components, in percents of mass: said sodium silicate - 10, technical water - 90. Said suspension as water-isolating material penetrates in non-coagulated form deep inside the bed of fractured collector. ^ EFFECT: creation of screen of backfilling of water-leading channels of high intensiveness by means of forming sodium silicate directly inside the bed. ^ 2 cl, 1 tbl, 1 dwg
