摘要
通过J55油管钢、20^(#)管线钢在饱含N_(2)、CO_(2)地层水的浸泡实验,利用Tafel曲线、线性极化曲线、交流阻抗谱图分析了CO_(2)含量对两种管材的腐蚀规律,在饱含N_(2)、CO_(2)的地层水中,随着N_(2)含量增加J55油管钢、20^(#)管线钢的CO_(2)腐蚀速率呈减小的趋势,随着CO_(2)气体含量的增加J55油管钢、20^(#)管线钢的腐蚀呈现增加趋势。
Based on the immersion experiment of J55 Tubing Steel and 20^(#)pipeline steel in formation water saturated with N_(2) and CO_(2),the corrosion law of CO_(2) content to two kinds of tubing was analyzed by Tafel curve,linear polarization curve and AC impedance spectrum.In formation water saturated with N_(2) and CO_(2),the corrosion rate of J55 Tubing Steel and 20^(#)pipeline steel decreased with the increase of N_(2) content,and J55 tubing steel decreased with the increase of CO_(2) content The corrosion of steel and 20^(#)pipeline steel is increasing.
