Review of microbial corrosion prevention and control technology in the petroleum industry

In the oil industry, microbiologically influenced corrosion (MIC) is widespread in aspects such as oil extraction, transportation, and processing. This type of corrosion not only causes structural damage to metal materials, leading to the corrosion and damage of equipment like oil and gas pipelines, storage tanks, and drill rods, thereby shortening their service life, but it may also trigger safety accidents such as fires and explosions, resulting in significant economic losses and safety risks for the oil sector. This article reviews the determination and detection of microbial corrosion, monitoring methods, and the current state of research on various corrosion prevention and control methods. It emphasizes the advantages and disadvantages of different prevention and control methods and their specific effectiveness. Furthermore, it summarizes and prospects the future development trends and challenges faced by MIC prevention and control, aiming to provide some references and guidance for the research on microbial corrosion control.
