冲刷

The flow velocity increased and reached the maximum on the hillslope within a three or four meters' downslope distance, and the flow velocities of each segment almost all decreased with increasing scouring duration in the scouring experiments.

坡面流流速在坡面的发展有一个坡长范围，试验中，在距坡顶3～4 m处，坡面流流速达到最大；坡面、沟坡各断面流速基本上都随着放水冲刷时间的延长而呈下降趋势。

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.

算例分析表明，水下井口的横向偏移及弯矩随张力比和海流流速的增加而大幅增大，顶张力过大会引起井口稳定性变差；随着钻井船或平台漂移量的增加，井口的横向偏移和弯矩近似线性增加，控制好钻井船或平台的漂移非常重要；由于井口承受弯矩的能力有限，较大海流流速情况下可能造成井口失稳；提高导管抗弯强度、控制泥线处管柱冲刷、获取浅部地层的取样数据等措施可以增强井口稳定性。
