摘　　要：海洋钻井隔水管系统是深海油气田开发必要的装备之一,关系到深水油气田钻完井生产安全。目前全球通用的隔水管系统分析软件都基于有限元分析方法,无法实现对隔水管系统的精细化建模和整体求解,论文通过先进的多体动力学求解方法,构建海洋钻井隔水管多体动力学求解器,实现了钻井平台-隔水管-水下井口系统的耦合分析,具有与全球先进隔水管专业分析软件类似的功能,如作业窗口、漂移窗口、模态、回弹分析功能,又具备更先进的精细化模型构建、内部钻井液和钻柱分析功能。该求解器对隔水管系统的分析水平带来较大的提升,具有广阔的应用前景。Marine riser system is necessary equipment in deep-sea oil and gas field development.At present,all the general riser system analysis software in the world is based on the finite element analysis method.Because it is impossible to achieve the overall solution of fine modeling of the riser system,the riser system should be simplified when using the finite element method.In this paper,a multi-body dynamics solver for marine drilling riser is constructed,and the rig-riser-subsea wellhead system coupled analysis is implemented.The solver has the same functionality as the global advanced riser professional analysis software,such as operation window,drifting,modal,recoil analysis function,and has more advanced functions such as refinement modeling,and analysis of internal drilling fluid and drill string.The solver has a broad application prospect.
