大斜度井开窗侧钻技术在辽河油区的应用探讨

Discussion on Application of Casing Window Sidetracking Drilling Technology in Liaohe Oil Area

随着辽河油区油井开发进入中后期,降本增效是辽河油区亟待解决的问题,故对老井的二次开发在逐年增加。目前,套管开窗侧钻钻井是老井二次开发的首选技术,所以大斜度井开窗侧钻钻井技术在辽河油区颇受青睐,施工了很多井次,积累了一些大斜度井开窗侧钻的宝贵经验。本文针对大斜度井开窗侧钻在辽河油区的应用进行探讨,希望能为其他油区进行大斜度井开窗侧钻提供参考依据。

The development of Liaohe oil area has entered the middle and late period, the cost reducing and efficiency increasing is an urgent problem in Liaohe oil area, so the secondary development of old wells is increasing year by year. At present, the technique of casing window sidetracking drilling is the first choice for the second development of old well, so the technology of large inclined well window sidetracking drilling is widely used in Liaohe oil area, and many wells have been constructed, and some valuable experience of large inclined well window side drilling has been accumulated. In this paper, application of casing window sidetracking drilling technology in Liaohe oil area was discussed, which could provide some reference for development of other oil areas.
