摘要
平台-隔水管-水下井口耦合系统是海洋钻采作业的核心设备,共同构成了水下生产作业的作业空间,并为泥浆返回提供通道,其动力学响应对海洋平台安全和正常作业意义重大。为此,文章采用有限元软件对耦合系统开展仿真分析,探究不同平台运动幅值对耦合系统动力学响应的影响。结果表明:耦合系统响应为非线性响应,耦合系统动力学响应随平台顶部偏移量的增大而增大。
The platform-riser-underwater wellhead coupling system is the core equipment of offshore drilling and production operations,which together constitute the working space of underwater production operations and provide a channel for mud return.Its dynamic response is of great significance to the safety and normal operation of offshore platforms.In this regard,the finite element software is used to simulate and analyze the coupling system,and the influence of different platform motion amplitudes on the dynamic response of the coupling system is explored.The results show that the response of the coupling system is nonlinear,and the dynamic response of the coupling system increases with the increase of the top offset of the platform.
