摘要： 采油树在深海油气开发中起着至关重要的作用。为了准确了解钻柱-采油树纵向下放安装过程的动力学特性，基于钻柱-采油树实际安装工况和动力学基本原理，考虑平台升沉运动，建立钻柱-采油树纵向振动力学仿真模型。在MATLAB中采用有限差分法对该模型进行离散求解。分析升沉补偿模式、PID控制器比例系数、补偿缸体积、水深、钻柱壁厚和采油树质量等因素对钻柱-采油树纵向振动性能的影响。仿真结果表明：主动式升沉补偿装置的补偿效果优于被动式升沉补偿装置；主动式升沉补偿装置中PID控制器的比例参数kp增大时，升沉补偿效果增强，但kp增大到一定值时会引起钻柱-采油树系统不稳定；钻柱-采油树的纵向振动位移随着补偿缸体积、钻柱壁厚的增大而减小；所受应力随着补偿缸体积、钻柱壁厚的增大而减小，随着采油树质量的增大而增大；在不同水深条件下，钻柱-采油树顶部的纵向振动位移和应力基本相同。研究结果可以为采油树稳定地下放安装提供参考。
Abstract: The production tree plays a vital role in the exploitation of deep-sea oil and gas. In order to accurately understand the dynamics characteristics of the vertical release and installation of the drill string-production tree, based on the actual working conditions of the drill string-production tree installation and the basic principles of dynamics, the longitudinal vibration dynamics simulation model of the drill string-production tree was established considering the heave motion of the platform. Discrete solution was solved by finite difference method in MATLAB. The influences of heave compensation, PID controller proportional coefficient, compensation cylinder volume, water depth, drill string wall thickness and production tree weight on longitudinal vibration performance of drill string-production tree were analyzed.The simulation results showed that the compensation effect of the active heave compensation device was better than that of the passive heave compensation device. In the active heave compensation device, if the proportional coefficient kp of PID controller increased, the heave compensation effect would be enhanced. However, as kp continued to increase, the drill string-production tree system would be unstable. The longitudinal vibration displacement of drill string-production tree decreased with the increase of compensation cylinder volume and drill string wall thickness.The stress decreased with the increase of compensation cylinder volume and drill string wall thickness, and increased with the increase of production tree weight. Under different water depth, the longitudinal vibration displacement and stress at top of drill string-production tree were basically the same. The research results can provide a reference for the stable release and installation of production tree.
