FIELD: oil and gas industry.
SUBSTANCE: invention relates to oil industry, in particular to compositions and methods for controlling coverage of oil beds flooding and limiting inflow of breakthrough gas or associated produced water, and can be used in development of oil deposits developed with maintenance of formation pressure by pumping water or other agents (gases and air). Method involves pumping to oil reservoir of 21–35 wt% aqueous suspension of reagent, containing 30–60 wt% of titanium coagulant, 10–40 wt% aluminum hydroxochloride and 30–60 wt% of carbamide.
EFFECT: high efficiency of the composition owing to longer service life, improved rheological properties of the gel obtained in formation conditions.
