FIELD: chemistry.
SUBSTANCE: invention relates to the oil extraction industry, particularly to compositions for increasing oil production. The composition for increasing oil production contains a polymer from the acrylic family, a non-ionic surfactant, a cross-linking agent and water. The said polymer from the acrylic family is an all-weather aqueous polymer, and the non-ionic surfactant is a waxy low-melting commodity form - SNO-3B, and the cross-linking agent is still waste liquid or calcium chloride or magnesium chloride with the following ratio of ingredients in wt %: all-weather aqueous polymer 3-10, SNO-3B 1-5, still waste liquid or calcium chloride or magnesium chloride 5-10, water - the rest.
EFFECT: more effective action of the precipitate-forming composition on waterlogged oil-bearing strata.
