摘要

全旋转内置式导向钻井工具是旋转导向钻井系统的重要部件之一,是一种全新结构形式的动态指向式井下闭环旋转导向钻井工具。为了研究全旋转内置式旋转导向钻井工具的运动状况,依据空间机构原理,建立了全旋转内置式导向钻井工具的动力学集中参数模型,进行了系统动力学分析,并通过Adams仿真验证了模型的正确性。结果表明:从理论上得出了关键部件偏心环和导向轴的速度、姿态等运动学基本参数,能够揭示姿态机构的运动特征,阐明偏心环和导向轴的转速、偏心距与钻头运动的关系,求得了导向系统中各参数随时间的变化规律,为全旋转内置式导向钻井工具的研究以及实现对钻井系统的最优设计打下理论基础。

Abstract

The full-rotation built-in steerable drilling tool is one of the important components of the rotary steerable drilling system.It is a new type of dynamic directional downhole closed-loop rotary steerable drilling tool.In order to study the motion condition of the full-rotation built-in rotary steerable drilling tool,based on the principle of space mechanism,The dynamics concentration parameter model of the full-rotation built-in directional drilling tool was established,and the system dynamics analysis was carried out.The correctness of the model was verified by ADAMS simulation.The results show that the basic parameters of velocity and attitude of the eccentric ring and the guide shaft of the key components are theoretically obtained,and the motion characteristics of the attitude mechanism are revealed.The rotational speed,eccentricity and bit motion of the eccentric ring and the guide shaft are studied.The relationship is obtained,and the variation of each parameter in the guiding system with time is obtained.It lays a theoretical foundation for the research of the full-rotation built-in directional drilling tool and the realization of the optimal design of the drilling system.
