摘要 针对深水钻井隔水导管在起下作业过程中的受力特点,建立了隔水导管系统受力与变形模型,并推导出了隔水导管系统的挠曲方程;在此基础上,根据能量守恒原理建立了隔水导管系统的固有频率方程。通过实例计算,研究了起下作业过程中隔水导管系统固有频率的分布规律,以期为海上钻井作业安全和管理提供科学依据。 According to the characteristics of stress exerted on the deepwater drilling riser during down and up operations,the mechanical model is built to get the flexure equation for the riser system,based on which the natural frequency equation of the drilling riser is established according to the energy conservation principle.The distribution pattern of the natural frequency of deepwater drilling riser during down and up operations is studied through case calculation and it is expected to provide a scientific basis for the safety and management of offshore drilling operation.
