| 摘 要： | 利用高温高压哈氏合金反应釜对P110SS油套管钢在不同H2S和CO2环境下的腐蚀行为进行了实验。研究了H2S和CO2分压对P110SS油套管钢腐蚀规律的影响,利用SEM、EDS、XRD等方法分析了腐蚀试样的微观形貌与结构特征,发现P110SS在较低温度条件下,H2S浓度非常低时,腐蚀特征与单纯CO2腐蚀规律相似,腐蚀速率比较高。在相同的H2S分压条件下,随CO2浓度增加,腐蚀速率依次增加。通过应力腐蚀开裂试验表明,P110SS在高温205℃条件下应力腐蚀开裂敏感较小。

| Abstract: | Corrosion behavior of P110ss tubing and casing steel was tested through simulation of actual corrosion environment containing H_2S and CO_2 in a autoclave.The effect of partial pressure of H_2S and CO_2 on the corrosion behavior of P110SS steel was investigated.Scanning electron microscopy,X-ray diffraction and energy dispersive spectrometer technique were used to analyze the micro-morphology and microstructure.The results indicate that the corrosion rate of P110SS steel is relatively high under conditions ... |
