管道在石油和天然气的生产和运输中起着重要的作用。选用成膜型缓蚀剂是控制油气管道内部腐蚀最经济、最可靠的方法之一。介绍了不同类型腐蚀的机理、特点，通过管道设备材料的选择、pH值稳定剂和缓蚀剂控制管道内部腐蚀情况，分析了油气管线有机成膜型缓蚀剂（咪唑啉、脂肪胺、乙氧基化胺、季铵化合物、含硫化合物、基于多胺衍生物的聚合物缓蚀剂）的研究现状和发展方向。表1参49

Pipeline played a significant role in production and transportation of oil and gas. The use of film-forming corrosion inhibitor was one of the most economical and reliable methods of controlling internal corrosion of oil and gas pipeline. The mechanism and characteristics of different types of corrosion was introduced. Through the selection of pipeline equipment material and the pipeline internal corrosion control of pH stabilizer and corrosion inhibitors，the research status and development direction of organic film-forming inhibitor using in oil and gas pipeline were analyzed，including imidazoline，fatty amine，ethoxylation amine，quaternary ammonium compound，sulfur compound and polyamine derivative based polymer inhibitor
