“海洋石油981”深水钻井平台钻井系统的优化设计

Design Optimization of Drilling System for Hai Yang Shi You 981 Deepwater Drilling Rig

“海洋石油981”是我国自行设计与建造的第六代深水半潜式钻井平台，担负着开发南中国海深海油田的艰巨使命。钻井系统是钻井平台作业的中心，其布置的合理性决定着钻井作业的效率。因此，如何对钻井系统进行优化设计，成为平台设计时一项非常关键的工作。本文通过对已建成“海洋石油981”平台钻井系统的设计进行分析，总结出该钻井系统的设计优点，为今后平台设计建造提供指导性参考。

＂Hai Yang Shi You 981＂ is the 6th generation deepwater drilling platform engineered and constructed in China. It will be used for exploration and development of deep-sea oil in the South China Sea. Drilling system is operation center for a drilling platform. Reasonably arrangement of the drilling system decides the drilling operation efficiency. Therefore, how to optimaize the design of the drilling system is one of the most important key tasks for engineering the platform. This paper gives a general analysis of the drilling system design for the built platform ＂Hai Yang Shi You 981＂, and summarizes the advantage of engineering, which providing guidance for future engineering and construction of new rigs.
