咪唑啉类缓蚀剂缓蚀协同效应的研究现状及展望

Review and Prospect of Imidazoline Corrosion Inhibitor Synergistic Effect

咪唑啉类缓蚀剂是油气田现用最普遍的缓蚀剂。而单一的咪唑啉类缓蚀剂的缓蚀效果并不理想,且成本较高。利用咪唑啉与其他物质间的协同效应增强其缓蚀性能的研究成为咪唑啉类缓蚀剂研究领域中的热点和重点。本文从六个方面对目前咪唑啉类缓蚀剂体系中的协同效应做了综述,对咪唑啉与不同物质间的协同机理进行了探讨,并对咪唑啉类缓蚀剂协同效应的研究方向进行了展望。

The imidazoline inhibitor was the most common use of corrosion inhibitor in oil and gas field.While The inhibition effect of single imidazoline corrosion inhibitor was not ideal, and the cost was high. The research about the synergistic effect of imidazoline had become a hotspot and focus in imidazoline inhibitor science. This paper reviewed the imidazoline corrosion inhibitor synergistic effect from six aspects, while the synergistic mechanisms were discussed. Furthermore, the research directions in the future on imidazoline inhibitor synergistic effect were prospected as well.
