【摘要】：可控弯接头试验台是可控弯接头旋转导向钻井工具研发的配套设备。本文首先对旋转导向钻井技术国内外研究现状进行了介绍;然后对可控弯接头进行研究,建立偏心环组运动学模型推导出工具角调节与工具面角调节过程所遵循的数学公式。分别对可控弯接头的工具角调节方法与工具面角调节方法进行了理论分析,提出三种可控弯接头工具角与工具面角的控制方式,并利用MATLAB软件分别对工具角调节过程和工具面角调节过程进行轨迹仿真。通过简化可控弯接头力学模型,得到了可控弯接头内、外偏心环在导向过程中受到的最大摩擦力与摩擦扭矩。确定了可控弯头试验台主要功能与技术参数,并对其系统组成进行了研究。通过SolidWorks建立了试验台虚拟样机,并用Simulation对虚拟样机的主要受力部件进行了有限元受力分析。通过对可控弯接头几何外形进行研究,提出了“三激光测量法”与“五激光测量法”。通过测量可控弯接头某一平面的三个点或五个点即可实现对可控弯接头导向过程进行动态监测。
[Abstract]:The controlled bend joint test rig is a necessary equipment for the development of rotary steering drilling tools. This paper first introduces the research status of rotary steering drilling technology at home and abroad, and then studies the controllable bending joint, and establishes the kinematic model of eccentric ring group to derive the mathematical formula of tool angle adjustment and tool surface angle adjustment. The adjustment methods of tool angle and tool surface angle of controllable bending joint are analyzed theoretically, and three control modes of tool angle and tool surface angle of controllable bending joint are put forward. The tool angle adjusting process and the tool face angle adjusting process are simulated by MATLAB software. By simplifying the mechanical model of controllable bending joint, the maximum friction force and friction torque of the outer eccentricity ring in the guide process are obtained. The main functions and technical parameters of the controlled elbow test-bed are determined, and its system composition is studied. The virtual prototype of the test-bed is established by SolidWorks, and the finite element force analysis of the main force components of the virtual prototype is carried out by Simulation. Based on the study of the geometry of controllable bending joints, the "three laser measurement method" and "five laser measurement method" are proposed. By measuring three or five points in a plane of a controllable bend joint, the dynamic monitoring of the steering process of the controlled bend joint can be realized.
