FIELD: oil and gas production. SUBSTANCE: composition, which can be used for controlling intake capacity profile in wells, contains 7-20% sodium silicate, and clay suspension (density 1.06-1.2 g/cu.cm), and additionally 1.0 to 7.0% of butadiene/styrene latex or vinylidene dichloride latex. EFFECT: increased efficiency of water insulation due to extra structurization of formed gels and to exclusion of gel synerisis process. 2 tbl |
