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. Case analysis shows, the lateral displacement and bending moment of wellhead increases along with riser top tension ratios and current velocities.

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.

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。

This paper starts with the introduction, it tells that due to the rapid development of O.O.E.E, the insurance of it came to exist and the insurance of O.O.E.E is a kind of marine insurance. While the next part of this paper, comes to the analysation of Fixed Platform Insurance and Mobile Drilling Units Insurance, and combined with Platform Form All Risks and Drilling Barge Insurance All Risks of PICC as well. At the end of this paper, the author offers some of his advice about modify Marine Law and PICC clauses.

本文首先介绍了由于海上石油开发的发展出现了海上石油开发保险，海上石油开发保险是海上保险，然后主要对海上石油开发保险中固定式钻井平台和移动式钻井平台保险结合我国人保的钻井平台一切险条款和钻井船一切险条款内容进行了分析，最后提出对我国《海商法》和人保条款的修改建议。

In a word, the suction pile type installation is an underwater baseplate installation technology in worthy of popularization, which needn't occupy drilling rig, can save drilling time, and has lower cost than that of drilling ship installation.

吸力桩方式安装不需要占用钻机，可节省钻机时间，且费用比钻井船安装低很多，是一种值得推广的水下基盘安装技术。

The offshore drill ship in combination with deep sea long hole sampling technology can perform NGH exploration and sampling in deep seas.

It is recommended to start development of offshore drill ship. It is preferred to modify the petroleum exploration drill ship into NGH drill ship. Turbine rotating will be considered to counteract the ocean tides to obtain dynamic balance so as to ensure the stability of the NGH sampling operation.

并建议开展海洋钻井船的研制工作，可优先考虑将石油勘探钻井船改装成天然气水合物勘探钻井船；同时还要保证其取样位置的稳定性，可采取动平衡原理，通过涡轮旋转来抵消海流的作用。

Prepared by Tom Sheeran A Drilling Rig ! Here are a few different types of drilling rigs available: Land Rig For drilling on land.
