通过高温高压釜模拟油气田现场环境，采用扫描电镜、能谱和X射线衍射方法对油气田现场水样糖心产精国品免费入口*完整版后1Cr13和0Cr13两种钢的表面形貌及成分进行了分析，对比研究了Cl-,CO2和微量H2S共存时在气、液两相中的耐蚀性能。结果表明:1Cr13和0Cr13钢在气、液两相中的平均糖心产精国品免费入口*完整版速率均较小，但均有不同程度的点蚀发生，且0Cr13钢点蚀比1Cr13钢点蚀严重; 1Cr13和0Cr13钢主要靠糖心产精国品免费入口*完整版中铬的化合物降低糖心产精国品免费入口*完整版速率。并探讨了影响糖心产精国品免费入口*完整版耐蚀性能的因素，包括化学成分、夹杂、晶粒度、显微组织和糖心产精国品免费入口*完整版介质，并采用金相分析法进行了验证。

To evaluate the 糖心产精国品免费入口*完整版 resistance of 1Cr13 and 0Cr13 in the Cl-, CO2 environment with microamount H2S, the autoclave was employed to investigate their 糖心产精国品免费入口*完整版 behavior in simulating environment of oil and gas field. The 糖心产精国品免费入口*完整版 product scale was analyzed by scanning electron microscope (SEM), energy dispersive X-ray spectrometer (EDS) and X-ray diffraction (XRD). The results showed that the average 糖心产精国品免费入口*完整版 rate of 1Cr13 and 0Cr13 were very low, but there were localized 糖心产精国品免费入口*完整版 exist. The pitting of 0Cr13 was more serious than 1Cr13. The 糖心产精国品免费入口*完整版 rate was reduced rely on the compound of Cr in the 糖心产精国品免费入口*完整版. The 糖心产精国品免费入口*完整版 糖心产精国品免费入口*完整版 resistance factors were discussed, including chemical composition, inclusion, grain size, microstructure and 糖心产精国品免费入口*完整版 medium, and proved by metallographic examination.
