抗CO_2腐蚀油气井缓蚀剂的研究与应用

Research and Application of Carbon Dioxide Corrosion Inhibitor for Oil and Gas Well

评述了抗CO2腐蚀缓蚀剂的研究与开发现状,根据油气井腐蚀介质的不同,常用的缓蚀剂主要有咪唑啉类、铵盐和季胺盐类、有机磷酸盐类等。介绍了其作用机理与现场监测手段,讨论了进一步的研究开发方向,局部腐蚀和高温高压腐蚀缓蚀剂的开发及其作用机理、性能评价与预测将是研究的重点方向,指出存在的不足并对其应用前景进行了展望。

The research and developing gas production industry were summarized.. Much situation of carbon dioxide corrosion inhibitor used for oil and interest has been devoted to organic inhibitors such as triazole type compounds, imidazoline, amide derivatives, etc. in various media. Its inhibiting mechanisms and spot detection methods were introduced. The prospects of application were anticipated. The trend for further research and development was also discussed.
