摘要:
利用美国Cortest公司高温高压反应釜模拟高含硫油气田H2S/CO2腐蚀环境，在流动高矿化度饱和H2S/CO2介质中进行试验，辅以SEM、XRD、动电位扫描及交流阻抗等表面分析和电化学技术，探讨了微量H2S对油管钢CO2腐蚀行为的影响，并对腐蚀产物膜特征及腐蚀机制进行了研究。结果表明：单一CO2腐蚀速率最高，达2.4 mm/a；当H2S与CO2分压比为1/400时，腐蚀速率迅速减小，随着H2S与CO2分压比增大，腐蚀速率先增大后减小，但均小于单一CO2腐蚀速率；H2S与CO2分压比为1/400是腐蚀控制的临界点，当H2S与CO2分压比大于1/400时，腐蚀过程逐渐转变为H2S控制。
Abstract:
H2S/CO2 corrosion environments in oil and gas field containing rich S were simulated in a high temperature and high pressure autoclave manufactured by USA Cortest Company, and tests were conducted in H2S/CO2  media with high salinity. The effect of small amount H2S on CO2 corrosion behavior of oil tube steel was discussed by the following technologies, such as SEM, XRD, dynamic potential scanning, AC impedance and electrochemical techniques, and the characteristics of corrosion conduct film and corrosion mechanism were studied. The results showed that the corrosion rate is the highest in pure CO2 corrosion, up to 2.4 mm/a. When the H2S/CO2  partial pressure ratio is 1/400, the corrosion rate decreases rapidly; with H2S/CO2  partial pressure ratio increases, the corrosion rate firstly increases then decreases, but are less than a single CO2 corrosion rate. H2S/CO2 partial pressure 1/400 is critical point of corrosion control. When H2S/CO2  partial pressure is more than 1/400, the corrosion process gradually transforms into H2S control.
