  Corrosion inhibiting formulations including a substituted benzimidazole, a mercaptocarboxylic acid, a 2-thioxodihydropyrimidine-dione, a sulfhydryl alcohol, a surfactant, and a solvent. Methods for preventing, inhibiting, or reducing metal (e.g. carbon steel) corrosion utilizing these formulations are described. The formulations are effective against corrosion of metallic substrates in sweet (i.e. CO2), sour (i.e. H2S), and/or high salinity environments commonly found in petroleum industry.

  缓蚀制剂包括取代的苯并咪唑、巯基羧酸、2-硫酮二氢嘧啶二酮、巯基醇、表面活性剂和溶剂。介绍了利用这些制剂防止、抑制或减少金属（如碳钢）腐蚀的方法。这些制剂可有效防止金属基体在石油工业中常见的甜（如 CO2）、酸（如 H2S）和/或高盐度环境中的腐蚀。
