摘　　要：水平井斜度大、水平段长,对各种下井工具及钻具要求高,施工技术难度大。通过现场施工及科学试验,得到了水平井大修施工的主要施工参数和技术手段,为今后水平井大修积累了经验。文章论述了水平井大修施工的工艺原理、原则及修井技术难点、工具选择方法和施工程序,对于水平井大修施工有一定的指导意义。Level wells have features of high tip rate and long level interval, all kinds of workover tools and pipes are highly demanded, it is hard to perform the level well workover, so the level well workover becomes a new research question. Through site work and scientific experiment, we have gotten the main work parameters and technology methods and we have accumulated some work experience for the level well workover. This brief introduction not only summarized the work principle, basis and workover technology difficult problems, but also discussed the methods of choosing tools and programs of the performing the level well workover. It will offer special guidance significance for level well workover.
