方正地区防斜打快技术研究与应用

Research and Application of Vertical and Fast Drilling Technology in Fangzheng Area

摘要:

针对方正地区地层倾角大、自然造斜率高、钻井速度慢、钻进周期长等特点，绘制井斜高发区域及层位，明确最易发生井斜地层为宝一段与新乌组，通过优选防斜、纠斜钻具组合及相应的钻进参数，同时结合复合钻进和垂直钻井系统，形成一套方正地区易斜地层的防斜打快方法，对于提高钻井速度，缩短钻井周期具有重要的指导意义。

Abstract:

There are large formation dip, high building rate, slow drilling speed and long drilling cycle in Fangzheng area. The high-risk areas and formations of deviation were drawn to confirm easy deviation formation of BaoⅠsection and Xinwu group; by optimizing anti-deviation BHA and drilling parameters and combining with compound drilling and vertical drilling system, a set of anti-deviation and fast drilling technology in easily inclined formation of Fangzheng area was formed, which can improve drilling speed and shorten drilling time significantly.
