用电化学法和现代物理检测分析手段,研究了辽河油田明化镇组深水井泵管的腐蚀。实验结果表明,泵管腐蚀是由于溶解氧、硫化氢、二氧化碳及微生物等共同作用产生的,反应主要为电化学过程。采用阴极保护技术,可有效地控制深水井泵管的腐蚀,还可有效地防垢、抑菌。 Electrochemical methods and modern physical detection and analysis methods were used to study the corrosion of deep well pump tubes in Minghuazhen Formation of Liaohe Oilfield. Experimental results show that the pump tube corrosion is due to the combined action of dissolved oxygen, hydrogen sulfide, carbon dioxide and microorganisms, the reaction is mainly electrochemical process. Cathodic protection technology, can effectively control the corrosion of deep well pump tube, but also effective anti-scaling, antibacterial.
