| 摘 要： | 随着含硫化氢腐蚀介质油气田相继被发现开发，硫化氢对油气田金属设备的腐蚀问题也日益严重。为了防止和控制硫化氢对油田金属设备的腐蚀，选取油田常用的20#钢、1Cr18Ni9Ti钢、316L钢和TA2钢，采用浸泡试验分析了4种常用钢在硫化氢环境下的均匀腐蚀行为，采用电化学试验分析了4种常用钢在硫化氢环境下的点蚀行为。综合分析两种试验结果发现:4种常用钢在饱和硫化氢溶液中的耐腐蚀能力由20#钢、1Cr18Ni9Ti钢、316L钢和TA2钢依次增强，其中1Cr18Ni9Ti钢在饱和硫化氢溶液中表现出明显的钝化趋势，采取相关的阳极极化措施可达到很好的防腐效果；316L钢和20#钢在饱和硫化氢溶液中的阴极极化率较大，采用阴极保护措施可以达到防腐的目的。

| Abstract: | With the increase of exploration and development of oil and gas fields containing hydrogen sulfide,the problem of hydrogen sulfide corrosion to metal equipment is becoming progressively serious.In order to prevent and control the hydrogen sulfide corrosion in oilfield,the uniform corrosion behavior of commonly used AISI 1020,1Cr18Ni9Ti,316L,and TA2 steel were investigated under H2S with immersion test.The electrochemical experimental method was used to analyze the spot corrosion behavior.Experimental result... |
