CO2/H2S 是油气田采集、运输、处理过程中主要的腐蚀介质，由其引起的管道设备的腐蚀问题变得越来越严重，腐蚀和防腐已经成为研究热点。分别对近年来国内外开展的有关CO2和H2S共存腐蚀及缓蚀技术的研究进行综述。CO2/H2S共存腐蚀研究主要依靠试验手段，但目前的研究结果有很大的离散性，根据不同的试验条件会产生不同的研究结果。分压比是国内外大多数学者研究CO2/H2S腐蚀规律的切入点，但关于两者主导腐蚀的分压比界限划分现有研究存有争议。缓蚀技术研究讨论了缓蚀剂作用机理，评述了抑制CO2/H2S共存腐蚀常用的酰胺类、咪唑啉衍生物类、季铵盐类和Schiff碱类缓性剂在国内外的研究与应用现状，展望了这一领域的研究前景及发展方向。

CO2 and H2S are main corrosive gases in gathering, delivering and processing of oil and gas, corrosion of pipeline and equipment caused by them are becoming more and more serious, resulting in corrosion and anti-corrosion researches as the study hot topics. CO2/H2S coexistence corrosion research mainly depends on experimental methods, but the present research results are not consistent, and different experimental conditions induce different research results. The partial pressure ratio of CO2/H2S is an important influence factor in corrosion environment, and it is also the entry point to study the corrosion behavior of CO2/H2S for most scholars. However, there is no agreement within current researches about the range of the partial pressure ratio. Practical experiences both at home and abroad show that, corrosion inhibitor protection technology is an economic, effective and practical method of metal protection, and it is especially suitable for application in oil and gas production. Research progress in recent years of the CO2/H2S coexistence corrosion on pipelines materials, including corrosion mechanism and anti-corrosion technology are reviewed, inhibition mechanism of corrosion inhibitors in CO2/H2S environment is discussed, overseas and domestic research status of amides, imidazoline derivatives, quatemary ammonium salts and Schiff bases are highlighted, finally, an outlook on the development trend of CO2/H2S corrosion inhibitors is presented.
