摘要
为分析老旧油田安全仪表系统可靠性,有必要对安全仪表系统进行SIL分析。基于SIL选择,油田SIL等级为SIL1及以上的SIF回路共计7个。利用exSILentia软件对其中5个SIF回路进行SIL验证,验证结果表明:涉及的5个SIF回路均满足SIL选择确定的SIL等级要求,符合各安全功能回路的功能安全需要。
In order to analyze the reliability of the old oilfield safety instrumented system, it is necessary to perform SIL analysis on the safety instrumented system. Based on the SIL selection, there are a total of seven SIF circuits with an SIL rating of SIL1 and above. SIL verification was carried out on five SIF loops using exSILentia software. The verification results show that the five SIF loops involved meet the SIL level requirements determined by SIL selection and meet the functional safety requirements of each safety function loop.
