摘要
系统总结了好氧生物膜的形成和发展机制,在此基础上着重介绍了铁氧化菌的代谢机制和对金属材料的腐蚀机理,分析了好氧微生物代谢产生的胞外聚合物在金属腐蚀过程中起到的作用。详细介绍了由典型的好氧铁氧化菌和厌氧硫酸盐还原菌引起的微生物协同腐蚀研究进展。总结了油田普遍采用的腐蚀防护方法以及最新研究进展,为后续铁氧化菌腐蚀与防护提供参考。
This paper systematically summarizes the formation and evolution of the iron oxidizing bacteria（IOB） related biofilm and the relevant mechanism,and then introduces the metabolic process of IOB and the corrosion process induced by IOB with emphasis on the role in the corrosion process of their metabolite of extracellular polymeric substance（EPS）.The paper also reviews the research progress of synergic corrosion induced by typical aerobic IOB and anaerobic sulfate reducting bacteria（SRB）.In addition,the paper further summarizes corrosion prevention methods applied in oilfields and the corresponding research progress,which may provide reference for the corrosion control for oilfield.
