摘要
油气田水下生产系统如果发生故障,将会给整个企业带来巨大的经济损失,并可能导致极大的环境问题,因此水下生产系统的可靠性尤为重要。基于可靠性框图分析方法,全面分析了南海油气田某水下生产系统,评估出该系统的失效率和MTTF,其中主控站的MTTF最小,只有8 071.0 h,是系统的最薄弱环节。另外,液压动力单元、水下阻塞模块、水下采油树和管汇模块是系统次一级的薄弱环节。该评估结果对今后水下生产系统的设计选择和维修方案有一定的指导和借鉴意义。
If the subsea production system fails in the oil and gas field, it will lead to great economic loss for the whole production and enormous problem of environment. Therefore,the reliability of subsea production system is particularly important.Based on the analysis method of RBD(Reliability Block Diagram), analyzing the subsea production system completely in the oil and gas field of south China sea. Evaluated the failure rate of this system and MTTF,the MTTF in main control station is the minimum, only 8071.0 h,is the most weak link of the system.In addition, the hydraulic power unit, the subsea blocking module,subsea tree and manifold module is the second level of the weak link of system.This evaluation result has certain guidance and reference significance for subsea production system future design choices and maintenance scheme.
