防斜打快技术在海拉尔易斜地层的研究与应用

Research and Application of Anti-deviation and Fast Drilling Technology in Easily Inclined Formation of Hailar

摘要:

针对海拉尔地区地层倾角大、断层多、岩性软硬交替、自然造斜率高等特点，绘制井斜高发区域及层位，明确易发生井斜层位，通过优选防斜、纠斜钻具组合及相应的钻进参数，同时结合随钻井斜预警系统和垂直钻井系统，形成一套海拉尔地区易斜地层的防斜打快技术，对于提高钻井速度、缩短钻井周期具有重要的指导意义。

Abstract:

According to the large formation dip, many faults, complex lithology and high nature deflecting rate in Hailar area, high-risk areas and formations of deviation were drawn to confirm easily inclined formation. By optimizing anti-deviation BHA and the corresponding drilling parameters and combining with early warning system and vertical drilling system, a set of anti-deviation and fast technology was formed in easily inclined formation of Hailar, which can significantly improve the drilling speed and shorten drilling time.
