摘要
针对川东地区含硫气田井下油管所处腐蚀环境和现状,通过对目前井下生产管柱的基本情况和腐蚀影响因素的分析,结合近年取样井油管腐蚀分析所取得的研究成果,并对目前气井井下油管生产适应性进行了深入探讨,总结出目前气矿油管腐蚀现象的基本特征。
For some sulfur gasfields in eastern Sichuan Basin,downhole tubing is almost in a corrosive environment.So,in this study,the fundamental situation of production string and its corrosive factors were analyzed;and then,the flexibility of current string was discussed on the basis of corrosion analysis obtained from sampled wells;at last,some basic features of corrosion for tubing were summed up.
