通过对马厂油水系统腐蚀机理的研究，发现集输管线以内腐蚀为主，外腐蚀甚微；输送介质中SRB含量高、矿化度高、游离CO2含量高、pH值低是造成腐蚀的直接原因。通过室内研究、矿场实验，采取了集输管线端点加药、在用旧管线玻璃钢外加固、水泥砂浆内衬修复、塑膜内衬修复等以内防腐为主要内容的技术措施。现场运用表明，综合治理防腐技术十分有效。 Through the research on the corrosion mechanism of the oil and water system in Machang, it is found that the corrosion in the pipeline is mainly dominated by external corrosion, and the SRB content in the transportation medium is high, the salinity is high, the content of free CO2 is high and the pH value is low, which is the direct cause of corrosion the reason. Through indoor research and field experiments, technical measures have been taken such as taking the end-point dosing of pipeline as the main content, using the external reinforcement of old pipeline FRP, cement mortar lining repairing and plastic lining repairing. The use of the site shows that the comprehensive management of anti-corrosion technology is very effective.
