摘要 研究了调制式旋转导向钻井系统控制井眼轨迹的原理和方式,依据实钻轨迹和设计轨迹的偏差大小,给出了轨迹控制方法。根据控制原理,设计了一套从地面控制井下的工具,以实现轨迹控制的指令算法。基于所研究的理论和算法,开发了应用于导向钻井系统的地面监控软件系统,重点介绍了井眼轨迹控制系统的程序设计与实现方法。 The well trajectory controlling principles and modes for modulated rotary steering drilling system were researched. According to the deviation between the actual well trajectory and the planned one, the well trajectory controlling method and the corresponding algorithm were determined. By using the algorithm for generating control commands, a downhole tool manipulated on the surface was designed to meet the requirements of the well trajectory control technology. The software of the surface monitoring and control system was developed. The design and implementation of the well trajectory control program were especially introduced.
