| 摘 要： | 采用动电位极化曲线与交流阻抗技术，针对辽河油田H2S含量对A3F与X70管线钢的腐蚀情况进行研究，并使用金相显微镜对腐蚀形貌进行了观察。结果表明，两种管线钢在电极过程中均呈现典型的活化控制；X70管线钢的耐腐蚀情况要明显优于A3F管线钢，腐蚀形态均为伴随着点蚀的局部腐蚀。

| Abstract: | The corrosion of A3F and X70 pipeline steel by hydrogen sulfide content in the Liaohe oilfield is studied by employing potentiometric polarization curve and AC impedance technique, and the corrosion morphology of two pipeline steels is observed by the metallurgical microscope. The results show that two kinds of pipeline steels exhibit typical activation control during the electrode process. The corrosion resistance of X70 pipeline steel is significantly better than that of A3F pipeline steel, and the corrosion forms are all local corrosion accompanied by pitting. |
