二氧化碳对油气田压力容器的腐蚀与防护措施

摘要

介绍了二氧化碳均匀腐蚀和局部腐蚀的机理，详细分析了二氧化碳腐蚀的各种影响因素，包括温度、CO2分压、pH值和介质组成等影响因素，并着重对油气田压力容器二氧化碳腐蚀的防护措施进行了总结。%The uniform and localized corrosion mechanisms of carbon steels in CO2 environment were introduced. The influence factors of CO2 corrosion, including temperature, partial pressure of CO2, pH value, components and so on, were analyzed in detail. Moreover, the prevention measures of CO2 corrosion on pressure vessels were summarized.
