Research on Progress of Microbiologically Influenced Corrosion Monitoring Methods

近年来,随着石油与天然气资源的大力开发,油气集输管道的腐蚀问题引起了人们的广泛关注,其中微生物腐蚀是导致管线服役失效的一大重要因素。建立快速有效的微生物检测方法及微生物腐蚀监测技术,可对腐蚀状态做出预判,为管道安全运作提供保障。针对这个问题,文中概述了微生物腐蚀机制,详细总结了各类微生物检测方法。从电化学角度出发,系统归纳了常用的微生物腐蚀的监测技术,并分析了不同技术的优缺点。在此基础上,提出了对于微生物腐蚀监测目前面临的挑战及未来研究方向。

With the rapid development of oil and gas, the corrosion of pipelines that for oil and gas gathering and transportation has attracted much attention. In particular, microbiologically influenced corrosion(MIC) has become a major factor that induces the failure of pipelines in service. The establishment of fast and effective microbial detection methods and microbial corrosion monitoring technology can predict the corrosion state and provide guarantee the safe operation of pipelines. In response to this problem, this paper summarizes the mechanism of MIC, and various microbiological tests methods in detail. From the perspective of electrochemistry, the commonly used monitoring technologies for microbial corrosion are systematically summarized, and the advantages and disadvantages of different technologies are analyzed. Based the literatures, we also talk about the current challenges upon MIC monitoring in practical application and propose the future research direction.
