用井下导向技术提高定向井钻井速度

Using Downhole Steering Technique to Improve Directional Drilling Rate

介绍了胜利油田应用井下导向技术提高定向井钻井速度的工艺方法和成功经验。给出了３种钻具组合形式，分析了井下导向技术的优势，探讨了携岩等技术问题并推荐了解决办法。５口定向井钻井试验表明，应用该技术后经济效益十分显著。

The downhole steering technique applied to improve directional drilling rate in Shengli Oilfield and its successful experiences were introduced. The paper presented 3 kinds of bottom hole assembly, analysed the advantages of downhole steering technique, discussed the problems such as rock carrying and recommended some solutions.Drilling applications in 5 wells show that the technique can bring remarkable economic benefits.
