摘　　要：微生物腐蚀(MIC)是导致石油天然气管道出现失效的主要原因之一。对管道微生物腐蚀进行了综述,包括微生物腐蚀行为及机理、微生物腐蚀的防治策略以及下一步研究的方向。微生物腐蚀的基本原因就是细菌附着在钢材表面,通过氧化还原反应造成腐蚀,会发生微生物腐蚀的菌种较多,因素较为复杂,需要进一步研究多因素、多菌种耦合作用下的腐蚀行为及机理。建议下一步,建立微生物腐蚀数据库,对腐蚀行为和机理进行大数据管理;持续开发抗菌管材,从合金的冶炼、钢板的轧制工艺和钢管的焊接工艺等方面综合考虑,进一步提升抗菌性能;关于杀菌剂的研发要注重杀菌性、经济性和环保性三大特点。Microbial corrosion(MIC)is one of the main reasons for the failure of oil and gas pipelines.In this paper,the microbial corrosion of pipelines is reviewed,including the behavior and mechanism of microbial corrosion,the prevention and control strategies of microbial corrosion and the direction of further research.Studies have shown that the basic reason for microbial corrosion is that the bacteria attach to the surface of steel and cause corrosion through redox reactions.There are many strains that will cause microbial corrosion,and the factors are more complicated.It is necessary to further study the corrosion behavior and mechanism under the coupling of multiple factors and multiple strains.It is suggested that the next step is to establish a microbial corrosion database and conduct big data management on corrosion behavior and mechanism.Continuous development of antibacterial pipe,taking into comprehensive consideration from the alloy smelting,steel plate rolling process and steel pipe welding process and other aspects,to further improve the antibacterial properties;the research and development of bactericide shall focus on the three characteristics of bactericidal activity,economy and environmental protection.
