摘　　要：油水井套管损坏不仅会直接影响井的正常生产,还会对邻井造成影响,甚至导致区域性套损,造成极大损失。对油水井套损部位的精准检测是实现高效修井的前提,为满足修井对测井资料的需求,近年来发展形成了系列工程测井技术,为套损井修井前期方案制定、修井中期工具深度校准、修井后效果评价及难于修复井报废提供了有效手段,修井措施的针对性和成功率逐步提高。同时,也分析了现有技术对疑难井检测不适应的原因,提出了服务于修井的工程测井技术发展方向。Casing damage not only directly affects normal production of the well itself,but also affects adjacent wells.Regional casing damage may cause a great loss.The accurate detection of damaged location is a precondition to carry out workover.In recent years,a series of engineering logging techniques have been developed for pre-workover plan,calibration of tool depth during workover,post-workover evaluation and well abandoning plan,improving the targets and success of workover measures.Finally,the unsuitability of existing engineering logging techniques are analyzed,and future development is proposed.
