进一步分析这套地层的有机地球化学特征后，提出壳质组含量和成熟度是决定石炭－二叠系能否生成轻质油的主要因素，并提出该区煤系地层生成轻质油的成熟度下限是镜质组反射率Ｒ０为１。
3.
These include proximate and ultimate analyses,BET nitrogen adsorption and thermogravimetry,It is found that the H/C ratio and VM content of exinite concentrate are the highest in three macer al concentrates,and these parameters of vitrinite concentrates are higher than those of inertinite concentrates.
结果表明，壳质组具有最大Ｈ／Ｃ比和最高挥发分含量，镜质组的Ｈ／Ｃ比和挥发分含量高于隋质组；显微组分的粘结性，镜质组大于惰质组；镜质组和惰质组相比较，镜质组的着火点低、燃尽温度也低，具有较窄的燃烧区间；壳质组的着火点最低，但是燃尽温度要高于镜质组。
