不同煤相煤的三维荧光指纹特征
Three dimentional fluorescencefingerprint characteristics of the coal withdifferent coal facies
【摘要】 本文应用三维荧光光谱指纹技术,研究了Ⅱ、Ⅲ两种煤相不同煤阶煤(Rmax°0.67%～1.07%)的三维荧光指纹特征.根据指纹图类型和特征指标F、α、K、R′的量值以及不同化石燃料样品的指纹参数范围,证实了Ⅱ煤相进入生油期的煤阶早于Ⅲ煤相煤.Ⅱ煤相煤生油潜力大于Ⅲ煤相煤.
【Abstract】 Using the analysing technique of the three dimentional fluorescence fingerprint, the authors studied the fluorescence fingerprint characteristics of differently ranked coal ( Rmax0. 67%-1. 07%)with two coal- facies II &. III ). Based on the fingerprint graphtypes, the values of characteristic indexes (F,a,K,R’)and the fingerprint parameter scopes of different fossil fuel samples,it is confirmed that the rank in which the generation of oil started for facies coal No.II is earlier than that for facies coal No.II and that the oil - generating potential of facies coal No.II is better than that of facies coal No.II.
