| 摘 要： | 以提高现有钻柱补偿装置的补偿性能为目的，研究钻柱动力学模型，在AMESim软件平台上搭建钻柱补偿装置系统模型，开展对钻井深度、海况、气瓶组容积、伺服阀前蓄能器4个补偿性能影响关键因子的研究。分析位置反馈、速度反馈和加速度反馈3种反馈型PID控制方法的特点，并对波浪预测和波浪跟随控制方法进行研究。仿真分析表明：主被动联合补偿可有效降低钻压波动，加入升沉预测的位置反馈控制方法对于提高补偿性能有明显的效果。研究结果可对钻柱补偿装置的设计和控制优化提供一定的指导意义。

| Abstract: | In order to improve the compensation performance of the existing drill string compensation system, we study on dynamics model of drill string, build the drill string compensation system model on the AMESim software to carry out the 4 key effect factors on compensation performance such as drilling depth, sea state, volume of air pressure vessel and the accumulator before serve valve. We analyze the characteristics of three feedback-type PID control methods of position feedback, speed feedback, acceleration feedback, and study the wave prediction and wave following control methods. The simulation analysis shows that the active-passive combined compensation can effectively reduce the drilling pressure fluctuation, and the position feedback control method with the heave prediction have obvious effect on improving the compensation performance. The research results can provide some guidance for the design and control optimization of drill string compensation system. |
