摘要
通过深水钻井隔水管时域非线性动态性能的研究,建立了相应的深水钻井隔水管时域非线性动态响应分析模型;基于ABAQUS软件,考虑钻井平台有一定的平均偏移、钻井平台位于不同平均偏移位置且在一阶波浪力作用下随机振动以及长期慢漂运动时钻井平台位于不同平均偏移位置且在一阶和二阶波浪力作用下随机振动等3种主要边界条件,通过实际算例对深水钻井隔水管的随机振动特性进行了仿真分析与对比。研究结论可以为今后深水钻井隔水管的设计与使用提供参考。
With the research on time-domain nonlinear dynamical performance of deepwater drilling riser, the related dynamic response model is established. The random vibration characteristics of deepwater drilling riser are analyzed and compared through an example based on ABAQUS for three main different boundary conditions, i.e. the platform is in the average offset, in different average offsets and under effect of first-order wave force, and in different average offset during long-term slow drift and under effect of first-order and second-order wave forces. The research conclusions have provided references to the design and application of deepwater drilling riser in the future.
