According to mechanical analysis of subsea wellhead for deepwater drilling, a comprehensive stability analysis method is established. The marine environmental loading, drilling vessel or platform drifting, riser mechanical behavior, nonlinear behavior between casing string and formations are considered.

根据深水钻井水下井口系统整体受力分析,建立了井口力学稳定性分析方法,该方法综合考虑了海洋环境载荷、钻井船或平台漂移、隔水管力学性能、套管柱与地层之间的非线性响应等因素的影响,可以实现井口力学性能分析。

The bigger top tension will cause the wellhead to be over-pulled and increase the probability of wellhead collapse. As the mean drifting of drilling vessel or platform increases, the wellhead displacement and bending moment nearly linear enlarges. The greater current velocity may result in wellhead instability because of its limited bearing moment capacity. Therefore the drifting control is very important to subsea wellhead stability. The wellhead stability may be improved by taking measures such as enhancing the conductor bending strength, controlling scour depth on seabed, getting geological data sampling of shallow formations.
