一种防止硫酸盐还原菌腐蚀的抑制剂
摘要：
防止硫酸盐还原菌腐蚀的抑制剂，应用于油井防止硫酸盐还原菌腐蚀。特征是：各组分重量比：a.含量为0.05％的多肽缩合试剂(HOOBt)C7H5N3O2的水溶液：13.5～18.0％；b.硫酸镁MgSO4·7H2O：2.0～5.0％；c.硫酸钠：1.5～4.5％；d.酵母膏：0.05～0.2％；e.磷酸氢二钾K2HPO4：0.5～2.0％；f.维生素C：0.05～0.5％；g.其余为水。效果是：采用本方法制备的防止硫酸盐还原菌腐蚀的抑制剂，在油井防止硫酸盐还原菌的过程中，在0.05～0.1％加量的情况下，使系统中硫酸盐还原菌的含量小于25个/ml。
摘要（英）：

Disclosed is an inhibitor applied in oil well for preventing against corrosion from sulfate reducing bacteria, which is characterized by comprising the following components: a. 0.05% by weight of aqueous solution of peptide coupling reagent (HOOBt) C7H5N3O2; b. 2.0-5.0% by weight of magnesium sulphate(MgSO4*7H2O); c. 1.5-4.5% by weight of sodium sulphate; d. 0.05-0.2% by weight of yeast extract; e. 0.5-2.0% by weight of dipotassium hydrogen phosphate(K2HPO4); f. 0.05-0.5% by weight of vitamin C; g. and the balance of water. During the process of preventing against corrosion from sulfate reducing bacteria in oil well, the inhibitor preventing against corrosion from sulfate reducing bacteria produced by the method can keep the content of sulfate reducing bacteria below 25/ml in the case of 0.05-0.1% addition of the inventive inhibitor.
