【摘要】：旋转导向技术在具备定向钻井功能的同时,还有效地借助钻柱运动减小了钻柱的摩擦阻力,延长了钻井极限距离。旋转导向技术具有安全性高,钻井速度快的优势,已成为石油勘探开发过程中不可或缺的要素,被广泛应用于超深井等结构复杂的钻井中。本文基于国内外对旋转导向技术的研究,对现有的AutoTrak、PowerDrive、Geo-Pilot三种典型的旋转导向钻井系统进行了理论和主要结构的说明,通过对比分析,得出现有系统的优势和不足。针对目前旋转导向钻井系统存在的问题,提出了机械式旋转造斜工具。阐明了该工具的定向外套、旋转控制器、液压驱动器等主要部分进行结构和功能,分析并计算了该工具受力情况和造斜能力。本文提出的机械式旋转造斜工具具有结构简单,成本相对低廉,能适应高温、高压的深井及复杂油气井中,具有良好的发展前景。
[Abstract]:The rotary steering technology has the function of directional drilling and effectively reduces the friction resistance of the drill string and prolongs the drilling limit distance with the help of drill string movement. With the advantages of high safety and high drilling speed, rotary steering technology has become an indispensable element in the process of oil exploration and development, and has been widely used in ultra-deep wells and other complex drilling structures. Based on the research of rotating steering technology at home and abroad, this paper explains the theory and main structure of the three typical rotary steering drilling systems of AutoTrakton Power driven Geo-Pilot. Through comparison and analysis, the advantages and disadvantages of the existing system are obtained. Aiming at the problems existing in the rotary steering drilling system, a mechanical rotary tilting tool is proposed. The structure and function of the main parts of the tool, such as directional jacket, rotary controller, hydraulic actuator, etc., are expounded, and the force situation and diagonal ability of the tool are analyzed and calculated. The mechanical rotary tilting tool presented in this paper has the advantages of simple structure, relatively low cost, and can be used in deep wells and complex oil and gas wells with high temperature and high pressure, and has a good prospect of development.
