摘　　要：断块油田进入开发中后期,剩余油高度分散、挖潜难度大,同时低产、停产及报废井越来越多。侧钻井由于投入少、施工简单、见效快等特点成为改善开发效果、提高油田采收率的有效手段。通过对断块油藏应用侧钻井挖潜剩余油技术进行分类、归纳、总结研究,形成了不同剩余油类型的10种侧钻井挖潜模式,并形成侧钻井选井及设计的规范,该模式在全油田进行推广应用。When fault block oil reservoir went into intermediary and later stage of development,oil remaining disperses seriously and it was difficult to unearth remaining oil.Meanwhile,amount of stripped well,closed well and abandoned well got more and more.Because of little input,single construction work and producing the desired result quickly of lateral well,it bacame a effective approach to improve development effectiveness and enhanced oil recovery for fault block oil reservoir.The technique of unearthing remaining oil by lateral well was classified,summed up and studied in fault block oil reservoir.And 10 patterns of unearthing different remaining oil by lateral well was built up.The paper established choosing well and designing criteria of lateral well.Finally,the patterns were popularized and applied in total oilfield.
