FIELD: oil and gas production. SUBSTANCE: invention relates to compositions limiting water inflow into oil and gas wells and leveling injectivity profile in injection wells of oil, gas condensate, and gas deposits with formation temperature 60 C and higher. Composition of invention contains, wt. % : urea, 15.0-25.0; aluminum chloride, 2.0-5.0; water-soluble polymer (methylcellulose), 0.5-1.0; and water, the balance. Composition increases oil recovery owing to increased filtration characteristics thereof at temperatures below 60 C and reduction of these characteristics because of enhanced viscosity properties at temperatures above 60 C up to creation of gel resistant to formation fluids and to high formation temperatures of 90 C and higher. Gel shows high strength at high shear rates at formation temperatures superior to gelation temperature of composition. EFFECT: improved working characteristics of composition. 1 tbl
