| 摘 要： | 采用失重法,测定了两种油田常用缓蚀剂（HJF-94和WSL-1）对浸没于含CO_2的模拟油田采出水的A3钢的缓蚀作用,并计算腐蚀速率和缓蚀率。实验结果表明：HJF-94缓蚀剂在较低质量分数范围（0-0.1%）有较好的缓蚀效果,在较高质量分数范围（2%-3.5%）的缓蚀率均高于90%；WSL-1缓蚀剂在较高质量分数（1.5%-3%）时缓蚀率均为99%以上；添加了缓蚀剂的金属表面腐蚀轻微,表面光滑,且不存在明显的点蚀倾向。

| Abstract: | The character and inhibitive efficiency of the two commonly used oil field corrosion inhibitors（HJF-94 and WSL1） on the A3 steel immersed in simulated extracted water of the oil field in which carbon dioxide dissolves ware tested respectively with a weight-loss method,and the rate of corrosion and the inhibitive efficiency was determind.The experiments indicate that the corrosion inhibitor HJF-94 performs good effects at a lower concentration（0～0.1%）and the inhibitive efficiencies are all over 90% at a higher concentration（2%～3.5%）.The inhibitive efficiency of WSL-1 are all over 99% at a higher concentration（1.5%～3%）.The corrosion on the surface of A3 steel in a corrosion medium with the inhibitor is slight,the surface of the metal smooth,and no pitting corrosion occurrs. |
