摘　　要：分析了油管的失效形式,即结蜡、结垢、偏磨、螺纹黏结、腐蚀,以及失效原因;归纳总结了旧油管修复技术的3个阶段,即分选+清洗+检测阶段、二次螺纹加工阶段和再制造技术阶段。建议在整合油田现有油管修复方法的基础上,制定相关行业标准,实现对旧油管的修复技术、生产过程、现场应用的标准化引导。Analyzed in the paper are various types of and causes for the failures of oil tubings, such as paraffin precipitation, scaling, eccentric wear, galling and corrosion. The repairing technology for used oil tubings is summerized as 3 stages, i.e. the sorting＋cleaning＋detecting stage, the re-threading stage, and the re-producing stage. It is recommanded to establish a relevant industry standard by integrating the current repairing methods for used oil tubings, so as to provide a standardized guidance to the repairing of used oil tubings, the manufacturing process, and the field application.
