摘要： 深水防喷器(BOP)作为深水井控关键部件,其可靠性对于保证深水钻井安全高效进行极为重要。通过分析墨西哥湾及中国海域深水防喷器失效事故案例、厂家安全公告并结合现场故障及维保经验,分析了"海洋石油981"平台(HYSY981)防喷器组失效故障模式。以井口连接器为例,进行失效模式及后果分析(FMEA),并通过基于信息公理(AD)与风险优先数(RPN)集结合的评估方法对风险因素科学排序。实例分析结果表明,通过FMEA分析,可以找出影响防喷器系统可靠性的潜在危险因素与薄弱环节,可从风险防控措施、风险处理方案、优化配件库存等方面为操作人员提供依据,实现提高深水防喷器系统可靠性的同时,也能为其他钻井相关设备系统提供支持。

Abstract:  As key component of well control system, the reliability of deepwater blowout preventer (BOP) is extremely important to guarantee the safety and high efficiency of deepwater drilling. By analyzing failure accident cases in Gulf of Mexico and the South China Sea, combining security bulletins and maintenance experience of field failures, we analyze the failure mode of HYSY981 BOP system, perform failure mode and effect analysis (FMEA) of wellhead and sorted risk factors scientifically based on information evaluation model combined with risk priority number (RPN). Analysis results show that with the proposed method, we can find out the potential risk factors affecting the reliability of BOP system, and provide basis for operators to achieve the goal of deepwater BOP system reliability from risk prevention and control measures, risk treatment scheme, optimization of parts inventory, etc.
