深水钻井平台-张紧器-隔水管耦合系统动力学特性分析

摘要
为精确预测隔水管系统动力学响应,解决传统分析方法中边界简化处理的问题,建立平台-张紧器-隔水管耦合动力学模型,充分考虑张紧器系统的非线性刚度变化以及平台、张紧器和隔水管的多体耦合连接方式,研究多体耦合系统中隔水管系统静态和动态响应特性,揭示平台-张紧器-隔水管耦合作用规律。结果表明:在隔水管系统静态分析中,张紧器系统能提供抑制隔水管系统偏移并减小隔水管系统弯矩的横向作用力;在隔水管系统动态分析中,张紧器系统对平台垂荡运动的传递具有明显的缩小效应;平台做纵摇运动时,有、无张紧器系统对隔水管系统偏移位置影响较大,对隔水管系统的运动幅值影响较小;平台-张紧器-隔水管耦合动力学模型能精确施加隔水管系统边界条件,更加准确预测隔水管系统的动力学响应。
To accurately predict the dynamic response of the riser system, and solve the problem where the boundary conditions are oversimplified in the traditional analysis method, a coupling dynamic model of deepwater drilling platform/tensioner/riser was established. Nonlinear stiffness variation of the tensioner system, as well as the multi-body coupling connection among the platform, the tensioner and the riser were fully considered in this new model. The static and dynamic response characteristics of the riser system were studied in the coupling system, and the coupling interaction manner of the drilling platform/tensioner/riser was revealed. The results show that,in the static analysis, the tensioner system provides a lateral force, which can suppress the offset and minimize the bending moment of the riser system. In the dynamic analysis, the tensioner system can significantly damp the transmission of the platform heave movement. When the drilling platform is in the pitch movement, the tensioner system has a great effect on the offset position of the riser system and has little effect on the motion amplitude of the riser. Compared with the traditional analysis model, the coupling dynamic model can apply the boundary condition precisely, and can accurately predict the dynamic response of the riser system.
