摘要
采用扫描电镜和X射线衍射技术分析DH1—H1井P110油管的腐蚀原因。结果表明 ,CO2 腐蚀是造成油管内壁腐蚀的主要原因 ,而CO2
Corrosion reasons of the tube used in DH1-H1 well were studied with SEM and XRD technology. All the results showed that CO 2 corrosion was the main cause of the inner wall corrosion ,cooperation of crevice corrosion and CO 2 corrosion were the forming reason of corrosion and pitting corrosion of the screw area.
