某油田采油厂掺输管网腐蚀严重,通过对其水质和腐蚀产物进行分析,查明了该掺输管网的腐蚀原因.认为结垢及垢下局部腐蚀是该管网腐蚀的主要特征,高氯离子、SRB和硫化氢是诱发垢下局部腐蚀的主要因素.同时还提出了防护对策.
The corrosion of pipelines in oil production plant of a certain oilfield is seriously corroded, and the corrosion causes of the pipelines are identified by analyzing the water quality and corrosion products.The local corrosion of scale and scale is considered to be the main feature of the pipe network corrosion, High chloride, SRB and hydrogen sulfide are the main factors that cause local corrosion of scale, and countermeasures are also proposed.
