中国石油网消息：4月8日，国际标准化组织“金属和合金的腐蚀”技术委员会（ISO/TC156）传来好消息，由工程材料研究院牵头制定的国际标准《金属和合金的腐蚀·油气输送管道微生物腐蚀试验方法》（ISO 21055：2026）获批正式发布。

China Petroleum News: On April 8th, the "Corrosion of Metals and Alloys" Technical Committee of the International Organization for Standardization (ISO/TC156) announced good news. The international standard "Corrosion of Metals and Alloys - Test Methods for Microbial Corrosion of Oil and Gas Transmission Pipelines" (ISO 21055:2026), led by the Engineering Materials Research Institute, was approved for official release.

这是中国石油在微生物腐蚀领域牵头制定的首个国际标准，标志着我国的腐蚀与防护技术实力与标准化水平迈上新台阶。

This is the first international standard jointly formulated by China National Petroleum Corporation in the field of microbial corrosion. It signifies that China's corrosion and protection technology capabilities and standardization levels have reached new heights.

微生物在油气田注水、水力压裂、油气集输与污水处理过程中，通过自身生命活动或代谢产物与金属发生反应导致的腐蚀，是目前油气管材和设备腐蚀失效的主要诱因之一。

During the processes of water injection in oil and gas fields, hydraulic fracturing, oil and gas transportation and wastewater treatment, microbial corrosion, which occurs when microorganisms react with metals through their own life activities or metabolic products, is one of the main causes of corrosion failure of oil and gas pipelines and equipment at present.

为解决油气管道微生物腐蚀风险评估、耐微生物腐蚀选材设计、耐微生物腐蚀材料/产品性能评价等长期无标准可依的难题，2018年以来，工程材料研究院发挥自身优势，依托中国石油、中国石化、中国海油等相关科研项目的支撑，牵头围绕页岩气开发、油气田注水、污水处理等工程实践，创新开展了系统的现场调研和实验研究，积累了丰富经验并掌握了大量核心数据。

To address the long-standing issues of lacking standards for assessing microbial corrosion risks of oil and gas pipelines, designing materials resistant to microbial corrosion, and eva luating the performance of microbial corrosion-resistant materials/products, since 2018, the Engineering Materials Research Institute has leveraged its own advantages and relied on the support of relevant scientific research projects from China National Petroleum Corporation, China Petrochemical Corporation, and China National Offshore Oil Corporation. It has taken the lead in conducting systematic on-site investigations and experimental research centered around engineering practices such as shale gas development, water injection in oil and gas fields, and wastewater treatment. This has enabled it to accumulate rich experience and obtain a large amount of core data.

2023年6月，在德国、沙特阿拉伯、捷克、韩国、美国、英国等国家的支持下，工程材料研究院主导的《金属和合金的腐蚀·油气输送管道微生物腐蚀试验方法》国际标准项目正式立项。

In June 2023, with the support of countries such as Germany, Saudi Arabia, the Czech Republic, South Korea, the United States, and the United Kingdom, the international standard project "Corrosion of Metals and Alloys - Test Methods for Microbial Corrosion of Oil and Gas Transmission Pipelines" led by the Engineering Materials Research Institute was officially initiated.

经过近3年的合作与努力，国际专家们针对油气输送管道的实际服役特征，系统规范了微生物腐蚀试验的原理、装置、溶液、步骤、菌种来源、试样制备、灭菌处理、结果评定及试验报告等全流程关键技术要求，形成了一套统一、规范、可比的试验方法。

After nearly three years of cooperation and efforts, international experts have systematically and precisely defined the principles, devices, solutions, steps, sources of bacteria, sample preparation, sterilization treatment, result eva luation and test report requirements for microbial corrosion tests based on the actual service characteristics of oil and gas transmission pipelines. They have thus developed a unified, standardized and comparable set of test methods.

作为油气管道安全运行的重要技术支撑，这一国际标准的发布，不仅填补了该领域国际标准体系的空白，而且为今后油气田微生物腐蚀相关研究提供了权威的技术依据，有力推动了全球油气管道腐蚀防控技术向更科学、更协同的方向发展。

As an important technical support for the safe operation of oil and gas pipelines, the release of this international standard not only fills the gap in the international standard system of this field, but also provides authoritative technical basis for future research on microbial corrosion in oil and gas fields. It has effectively promoted the development of global corrosion prevention technologies for oil and gas pipelines towards a more scientific and collaborative direction.
