【摘要】：针对连续管钻井过程中无法实时摆正工具面的问题,在设计电液定向工具的基础之上,分析了该工具实时调整工具面的方法。以圆弧扭方位计算模式为理论基础,建立了求取设计轨迹离散点的工具面角度计算模型。根据工具面角度调整特点及电液定向工具的结构参数,建立了电液定向工具液压缸控制工具面调整的数学模型。通过实例分析表明,该新型电液定向工具解决了传统定向工具的定向偏差问题,满足实时精确摆正工具面的要求,提高了连续管钻井的定向效率,为国内连续管钻井高端定向工具的研究提供一定的指导作用,有助于国内连续管钻井的发展。
[Abstract]:Aiming at the problem that the tool surface can not be adjusted in real time during continuous pipe drilling, the method of adjusting the tool surface in real time is analyzed on the basis of the design of the electro-hydraulic orientation tool.Based on the calculation model of arc torsional azimuth, a tool surface angle calculation model for calculating discrete points of design trajectory is established.According to the characteristics of tool surface angle adjustment and the structural parameters of electro-hydraulic orientation tool, the mathematical model of hydraulic cylinder control tool surface adjustment for electro-hydraulic orientation tool is established.The analysis of an example shows that the new electro-hydraulic orientation tool solves the problem of the orientation deviation of the traditional directional tool, meets the requirements of the real-time and accurate alignment of the tool surface, and improves the directional efficiency of the continuous pipe drilling.It provides some guidance for the research of high end directional tools for domestic continuous pipe drilling, and is helpful to the development of domestic continuous pipe drilling.
