摘　　要：目前矿用钻机向着自动化方向发展,为了解决自动钻进过程中钻杆加接时旋接螺纹干涉的问题,提出了采用自适应最小能量原理的技术,介绍了旋接螺纹过程中系统消耗的能量与压力的关系,分析了系统自动寻找能量最低点的过程,并分析了当控制特性发生变化时,系统如何自适应地调节控制参数以适应这一变化,找到新的能量最低点,顺利地进行螺纹旋接。Now the drilling rig is becoming more automatic. In order to solve the problem of intervene when the drill pipe screw with each other, The paper presents the drill pipe screwing technology based on self-adaption minimum energy principle, narrates the relationship of energy and pressure when drill-pipe screwing thread, analyses the process of the system seeking the point of minimum energy and also analyses when the system control features have changed, how the system changes its control parameter to suit this change, to find the new point of minimum energy, and screw the thread smoothly.

关 键 词：旋接螺纹 能量最低点 推进控制量 特征点 特征曲线 自适应
