摘　　要：吉林油区有相当数量的井下事故井常规大修作业手段无法处理,经施工经验总结,结合近年引进的新技术,针对实际井况开展了大修疑难井修复工艺技术的研究运用,通过对套内外使用高效磨铣类工具、套内打通道技术、新型膨胀管套管补贴技术、中浅层取换套管技术以及常规大修技术的综合利用,反复摸索整理形成了一整套成型的疑难井修复治理技术。Jilin oil area has a considerable number of down hole accident wells and the conventional means of repair work can not be processed.By summarizing of construction experience,combining with the introduction of new technologies in recent years,research of repair technology for overhaul difficult well to the actual well conditions is carried out.Through comprehensively using efficient tools for grinding milling at internal and external case,technology of comprising channel in case,new type of expansion pipe casing subsidy,pulling and changing case in the middle shallow layer and conventional overhaul,a set of well repair control technology for the difficult wells is produced by exploring and finishing again and again.
