中文摘要:渤海北部LD油田在井网加密、油田大规模综合布置新钻调整井时，存在新钻的25口井与老井井网交叉、井眼轨迹立体三维缠绕问题，其中C6H水平井是此类问题的典型，同时C6H井还需要在可钻性极差的馆陶组底砾岩地层定向造斜。针对上述问题，通过C6H井3种轨迹方案对比、分析，优选出最为有利的方案，结合螺杆马达和旋转导向工具性能分析，最后采用螺杆马达 水力震荡器 微偏心稳定器等钻具组合新方式，顺利实施了C6H井。

Three Dimension Trajectory Optimization and Control Technology for Unconventional Well Construction in Bohai
Abstract:For well pattern infill and large-scale comprehensive arrangement of newly drilled adjustment wells in LD oilfield of northern Bohai, 25 new wells cross with old well pattern and three-dimensional winding of borehole trajectory result in all the wells are three-dimensional designed with serious wellbores crossing problem, the typical case is C6H horizontal well which should be directional deflecting drilled in the Guantao formation basal conglomerate layer with extremely poor drillability. Aiming at the above, through the comparison and analysis on 3 kinds of trajectory scheme for C6H, the most favorable design is optimized; combined with the performance analysis on the screw motor and rotary steerable tools, new mode of DHA with screw motor hydro-oscillator micro eccentric stabilizer is adopted, C6H has been smoothly completed.
