应用荧光显微组分定量评价煤的生烃排烃潜力

QUANTITATIVELY EVALUATE HYDROCARBON GENERATING AND EXPELLING POTENTIAL OF COALS USING PARAMETER OF FLUORESCENT MACERALS

在研究镜质组类型基础上,把富氢镜质组(荧光镜质体)作为有折扣的富氢显微组分(类脂组)对待,提出了利用荧光显微组分丰度——FMT 参数作为评价不同还原类型煤生烃、排烃的定量指标。煤岩学标志、有机地球化学参数和热模拟实验产烃率数据为 FMT 值定量评价煤生烃排烃潜力的适用性和有效性提供了佐证。

on the basis of type-vitrinite,authors think that perhydrous vitrinites(fluorescent vitrinite)should be considered discounted rich-hydrogen maceral(liptinite)and this is suggested that using“abundanceof fluorescent)macerals—FMT)”may be as quantitative index of hydrocarbon generation and expulsion ofcoals in different type-reductibility.Marks of coal petrology,parameters of organic geochemistry and yield-oil of thermal simulate--d experiment are provided evidence for availability of“FMT”evaluation method.
