| 摘 要： | 海洋钻井隔水管是连接海底井口与钻井船的重要设备，文中利用描述隔水管运动的四阶非线性偏微分方程，应用有限差分法对隔水管的受力情况进行数值分析，考虑了顶张力和浮力块以及其他因素对隔水管的影响，并编制了相应的计算软件。文中所提供的力学分析方法及计算程序具有方法简便、计算精度高和运算速度快等特点，能够为深水钻井隔水管设计和校核提供可靠的理论依据和指导，具有较好的应用价值。

| Abstract: | Offshore drilling risers are important for connecting seabed wellhead and drilling vessels. By using fourth-order nonlinear partial differential equations for describing riser movement and the finite difference method (FDM), simulation analysis is conducted on riser forces. Considering the effect of top tension, buoyancy blocks and other factors on riser, corresponding calculation software is developed. The mechanical analysis and calculation program put forward in this paper feature in simplicity, high efficiency and high speed of calculation. They may be well applied to deep water drilling riser design and verification. |
