利用电化学工作站,结合微观腐蚀形貌分析,通过组合套管在高矿化度地层水中的腐蚀试验,研究了组合套管电偶学腐蚀规律及力学性能影响规律.结果表明:电偶腐蚀对套管的屈服强度及抗拉强度影响较小,为钻采方案设计提供了理论支撑.

This paper presents the corrosion experiment about water in high salinity formation with the combination of casing. Based on the micro morphology analysis with electrochemical workstation,we also discussed the corrosion behavior of combination casing galvanic and related mechanical properties. The results showed that galvanic corrosion play a little effect on yield strength and tensile strength of casing,which can provide the theoretical support for the drilling and producing project design.
