| 摘 要： | 海洋钻井平台的升沉运动对钻柱、钻压以及钻井操作具有较大影响.建立海洋浮式钻井平台钻柱系统动力学模型,利用级数法和机械振动理论求解得到钻柱系统运动响应,推导得出大钩位移量与钻压变化量的数学公式,通过Matlab计算得到给定钻柱长度下大钩的允许位移.分析计算结果为浮式钻井平台升沉补偿装置的开发提供设计依据,可以作为升沉补偿...

| Abstract: | The heave motion of offshore drilling platform has a great impact on the drill string,weight on bit and drilling operations.A dynamic model of drill string system for floating drilling platform was developed.Using series method and mechanical vibration theory,the motion response of drill string system was obtained,and then the mathematical formula expressing the relationship between the hook displacement and the weight on bit variation was derived.The allowed values of hook shift were calculated by Matlab u... |
