FIELD: oil and gas industry.
SUBSTANCE: invention relates to the oil and gas industry, in particular to compositions for stimulating oil production and developing wells by acidizing high-temperature collectors. The dry acid composition for acid treatment of collectors contains, wt.%: corrosion inhibitor INVOL-2 0.1-0.5, ampholytic surfactant "Neftenol VES" 0.5-1.5 and glycolic acid the rest up to 100.
EFFECT: invention ensures a more effective dissolution of the rock, increasing the permeability of collectors, eliminating the formation of deposits when an acidic process solution comes into contact with the rock and reducing the corrosiveness of steel at elevated rock temperatures.
