FIELD: oil and gas production.
SUBSTANCE: invention relates to the protection of steels in hydrochloric acid media; it can be used in oil and gas production during hydrochloric acid processing of carbonate rocks. The invention consists in the use of 5-(2,4-dimethoxyphenyl)-1,3,4-thiadiazolyl amide of 2,4-dimethoxybenzoic acid. The invention consists in the application of 5-(2,4-dimethoxyphenyl)-1,3,4-thiadiazolamide of 2,4-dimethoxybenzoic acid
as an inhibitor of hydrochloric acid corrosion of carbon steel.
EFFECT: expansion of the range of hydrochloric acid corrosion inhibitors.
