中文摘要：

提出了一种动态偏置指向式旋转导向钻井工具的工具角与工具面角调节的控制方法。通过建立运动学模型,分别对钻井工具的工具角调节方法与工具面角调节方法进行了理论论证,并将2种不同参数的调节方法加以合并,对导向工具的整个控制过程进行分析,提出3种对可控弯接头工具角与工具面角的控制方式,利用MATLAB软件分别对工具角和工具面角调节过程进行轨迹仿真。研究实现了导向工具根据工作需要对工具角和工具面角的灵活调节,并且在工具角与工具面角调节完成后使整个系统处于稳定状态。

英文摘要：

An adjustment and control method for the tool angle and the tool face angle of dynamic offset point-to-bit rotary steering drilling tool was put forward,and it was theoretically demonstrated through establishing the kinematic model of the eccentric structure. Three adjustment and control ways of the tool angle and the tool face angle of the controllable sub were proposed through the combination of two types of parameter adjustment ways and the analysis of the whole control process of the steering tool. The adjustment trajectories of the tool angle and the tool face angle are simulated using MATLAB software,and it is shown that to use the adjustment and control method can realize the flexible adjustment of the tool angle and the tool face angle of the steering tool according to need,and the whole system is in stable state after the tool angle and tool face angle adjustment is completed.
