高温高压井钻井平台甲板可变载荷研究

Variable load research of drilling platform deck for high temperature and high pressure well

高温高压井作业期间,各类物资存放和常规井完全不一样,对钻井平台甲板可变载荷有更高的要求。针对几种特有的工况,通过计算实例说明高温高压井作业与常规井作业甲板可变载荷之间的区别,为国内海上高温高压井作业平台提供一定的参考,也为钻井作业方平台选型提供一定的依据,并为将来攻克海上超高温高压井提供一些基础信息。

The storage of various materials during the operation of high temperature and high pressure wells are completely different from that for normal wells, which has a higher demand for the variable loads on the drilling platform deck. This paper presents the differences of the variable deck loads between the operation of high temperature and the high pressure wells and the normal wells by the practical computation cases according to several special operation conditions. It can provide certain reference for the drilling unit of the domestic high temperature and the high pressure offshore wells, and a basis for the operator to choose the drilling platform,as well as some basic information to conquer the ultra high temperature and the high pressure offshore wells in future.
