Discussion on Configuration of Subsea BOP Stack and Its Control System in Ultra-Deep Water
-
摘要: 超深水海域海洋环境极其复杂,对保证钻井安全的防喷器组及其控制系统的要求非常高。针对目前超深水防喷器组及控制系统没有统一的配置规范与标准和我国该方面产品研发及配置尚处于起始阶段的现状,提出了一种比较合理的防喷器组及控制系统配置方案。分析该方案中防喷器组中各种防喷器的功能和作用及控制系统的控制方法和特点,发现该方案与现行技术标准及HYSY981超深水钻井装置的防喷器组及其控制系统的配置方案相比,提高了对剪切防喷器的要求,并将备用控制系统和特殊控制系统作为了必配项目,超深水钻井作业的安全性和可靠性明显增强。Abstract: Based on the extreme challenge of environment in ultra-deep waters,the requirements on the BOP stack and its control system are very high in order to ensure secure operation.In view of the current situation,an unified standard for ultra-deep water BOP stack is still unavailable in the oil industry and the research and development of BOP stack is also in its infancy in China.An enhanced configuration was put forward through analyzing functions of the subsea BOP and its control system.Different from the present technical standard and the configuration of HYSY981 ultra-deep water drilling unit,the capacity of shear ram is improved and the backup and special control system are compulsory items in this configuration,which improves the safety and reliability of ultra-deep water drilling operation significantly.
