摘要：
缓蚀剂是酸液中较为重要的一种添加剂，针对冻胶酸对油管、套管及井下金属设备的腐蚀，研究了一系列单一缓蚀剂的缓蚀效果，并通过复配得到高温复合型缓蚀剂—NKJ。静态腐蚀实验得到此复合型缓蚀剂在90℃、浓度为20％的盐酸的冻胶酸中的缓蚀率为98.0％，达到行业三级标准，高温高压动态实验得到该缓蚀剂平均腐蚀率为28.96 g/(m2•h)，达到行业一级标准。

Abstract: The corrosion inhibitor is a very important additive in the acid fluid. Aiming at the corrosion of gelled acid to the tubing, casing and well equipment, the inhibiting effect of a series of single corrosion inhibitor have been studied, and a compound corrosion inhibitor NKJ used in high temperature has been developed. The result of the static corrosion experiment indicates that the inhibitor efficiency of the compound corrosion inhibitor is 98.0% in the gelled acid at 90℃ and the concentration of hydrochloric acid in the gelled acid is 20%, and it achieves the third level standard. The result of the dynamic experiment under high temperature and pressure indicates that the average corrosion rate of the corrosion inhibitor is 28.96 g/(m2h), and it achieves the first level standard.
Key words: gelled acid, compound corrosion inhibitor, corrosion rate, inhibitor efficiency
