摘　　要：随着油气田工业的发展,金属材料在H2S/CO2环境下的腐蚀问题极大地限制了油气行业的开发,研究石油专用管钢材在此条件下的腐蚀及防治方法已经迫在眉睫。本文针对集输管线用钢,简述其在H2S、CO2及H2S/CO2环境中的腐蚀与类型,重点讨论了腐蚀的反应机理及其影响因素,以期更为精准地掌握腐蚀规律,并为新防护技术的发展提供理论依据。With the development of the oil and gas field industry, the corrosion of metal materials in the H2S/CO2 environment had greatly restricted the development of the oil and gas industry. It was imminent to study the corrosion and prevention methods of steel for special oil pipes under these conditions. In this paper, the corrosion and types of H2S, CO2 and H2S/CO2 were described in the collection pipeline steel. The reaction mechanism and influencing factors of pitting corrosion were summarized. In order to accurately determine the corrosion rate, the corresponding protection method could be studied.
