【摘要】 诊断比值是油指纹鉴别中非常重要的鉴别指标,本文基于重复性限这一经典的统计学概念,详细介绍了利用重复性限进行溢油鉴别中诊断比值比较的方法,包括方法原理、诊断比值的评价及鉴别原则,并以某原油及其风化样品以及2种不同原油的油指纹鉴别为例,说明了此种方法的有效性,这对于提高基于油指纹的溢油鉴别准确度和效率将有重要意义。更多还原

【Abstract】 The diagnostic ratios play an important role in the oil fingerprint identification,and studies on the comparison method of diagnostic ratios have been developed in Europe,Canada,and China.This paper,based on the statistic conception of repeatability limit,the repeatability limit comparison method of diagnostic ratios in oil fingerprint were introduced,including the repeatability limit comparison principle,diagnostic ratios evaluation,and identification method.In addition,two identification examples were used in this paper to validate the method.The first identification was performed between a crude oil sample from sea oil platform and its artificial weathered oil sample.The second identification was carried out between two different crude oil samples,: one came from sea oil platform and the other came from land oilfield.The identification conclusion showed that the repeatability Limit comparison method of diagnostic was effectual and feasible in oil fingerprint identification,and significantly improved the precision and efficiency.更多还原
