摘要
采用宏观检测、机械性能测试、腐蚀产物分析等方法,研究了威远页岩气田某平台失效管段的腐蚀失效原因。结果表明,水中SRB、CO2、Cl-是引发腐蚀的主要因素。
Through the methods of macroscopic detection, mechanical performance test and corrosion products analysis etc, the reasons of failure pipeline within some platforms in Weiyuan shale gas field were studied. The results show that the main factors causing corrosion are sulfate-reducing bacteria existing in water, carbon dioxide and chloride ions.
