摘要
目前管道腐蚀在石油天然气行业不断受到研究者重视,而控制管道腐蚀最直接有效的方法是添加缓蚀剂,因此在微生物腐蚀、垢下腐蚀和管道顶部腐蚀机理的基础上分析有效缓解这3种腐蚀形态的缓蚀剂,得出添加的缓蚀剂在接近临界胶束浓度(CMC)时,缓蚀效果最佳。最后,提出未来新型缓蚀剂低毒、高效、适用范围广的发展方向。
At present,the pipeline corrosion in the oil and gas industry has attracted more attention,and the most effective and direct way to control pipeline corrosion is to add corrosion inhibitor.Therefore,based on the mechanism of microbial corrosion,under-deposit corrosion and top of the line corrosion,an analysis was made on 3 forms of the most effective mitigation of the inhibitor.The conclusion is drawn that when the added inhibitor is close to the critical micelle concentration（CMC）,the effect of the inhibitor is better.Finally,the development trend of new type corrosion inhibitor with low toxicity,high efficiency and wide application range is proposed.
