摘　　要：对YH23-1-18采油树阀门、立管进行了腐蚀检测,并从二氧化碳分压、温度与腐蚀产物膜以及腐蚀形态等方面进行了分析,结果认为,阀门、立管腐蚀为典型的二氧化碳腐蚀,并提出了预防措施。The article introduced the corrosion inspection of Christmas tree valve and riser in YH23-1-18 gas well from the CO2 partial, temperature and corrosion modality. The results indicated that the valve and riser＇s failure was resulted from the carbon dioxide corrosion and proposed the anticorrosion measure.

关 键 词：阀门 立管 二氧化碳 腐蚀
