摘　　要：在高温高压条件下 ,对 P110 ,N80 ,J5 5三种油管钢在模拟油田 CO2 环境下的腐蚀性能进行了研究评价 ,结果表明 :在静态条件下 ,三种钢对温度和压力的依赖关系均为类似抛物线规律 ,P110最不耐蚀。动态条件下对 P110钢的进一步研究显示 ,由于流速的存在 ,与静态下相比 ,最高均匀腐蚀速率点向温度和The corrosion behaviors of P110,N80 and J55 were investigated in the simulated high temperature and high pressure CO 2 corrosion environment The results showed that,under the static condition,the corrosion rate varies with temperature and CO 2 partial pressure as a parabola curve for all three kinds of steels Among these steels,the P110 steel has the least resistance to corrosion,Under the dynamic condition,the peak of uniform corrosion rate tends to shift in the direction of increasing temperature and pressure
