摘　　要：从CO_(2)的腐蚀机理、腐蚀影响因素(如CO_(2)分压、温度、pH)介绍了CO_(2)腐蚀研究现状,高温、高压对管道腐蚀速率影响较大,需采取合适措施。重点综述了加入缓蚀剂、耐蚀管材、涂层等防腐方法,结合机理以及防腐措施,提出了未来绿色高效、低成本、低污染的绿色防腐材料的研究趋势。The current status of CO_(2) corrosion research is introduced in terms of CO_(2) corrosion mechanism,corrosion influencing factors such as CO_(2) partial pressure,temperature and pH.High temperature and high pressure both have a great impact on the corrosion rate of pipelines,which needs to take appropriate measures.Anti-corrosion methods are reviewed,such as adding corrosion inhibitors,using corrosion-resistant pipes,using coating,etc.Combining the mechanism as well as anticorrosion measures,the future research trend for efficient,low-cost,low-pollution and green anticorrosion materials is proposed.
