FIELD: oil, gas and coke-chemical industries.
SUBSTANCE: invention relates to insulation works and increasing oil recovery of flooded formations at operation of gas and oil wells. Composition for increasing oil production, including polymer reagent AC-CSE-1313 grade A, acid and mineralized water, contains sulphamic acid as an acid and additionally - carboxymethyl cellulose and sulphanol, with the following ratio of components, wt. %: reagent AC-CSE-1313 grade A 0.1–1.35, sulfamic acid 0.1–1.35, carboxymethyl cellulose 0.03–0.1, sulphanol 0.07–0.2, mineralized water is the balance. Invention is developed in subclaims.
EFFECT: technical result is high efficiency and manufacturability of the composition, broader raw material resources.
