摘要： 深海钻井作业中使用运动补偿装置对钻柱运动进行补偿，补偿后钻柱受力及运动将产生较大的变化.本文采取有限元分析方法对运动补偿后的钻柱进行非线性动力学分析.分析结果表明，运动补偿后的钻柱是安全的，而补偿装置的受力在海水的影响下发生了较大的变化.

关键词: 运动补偿；动力学分析；深海钻井；钻柱

Abstract: The motion compensation devices are often used for the movement of drill strings in deep-sea drilling operations,and the load and movement of the drill strings will greatly change while being compensated.A nonlinear dynamic analysis of drill strings was conducted.The results show that the drill strings are safe after they are compensated and that the force on compensation devices is influenced by sea water.

Key words: motion compensation; dynamics analysis; deep-sea drilling; drill string
