摘要
应用煤岩学与有机地球化学分析方法，对比研究了两种不同还原型腐殖煤的成烃潜力。较强还原型腐殖煤富含荧光镜质体，具较强的荧光性、较高的Ｈ／Ｃ原子比、较多的氯仿沥青和总烃、较大的热解生油潜量和较高的液态烃产率，均显著区别于较弱还原型腐殖煤。可见，较强还原型腐殖煤比较富氢，具有较高的成烃潜力，特别是生成液态烃的潜力。
By using methods of coal petrology and organic geochemistry,this paper is carried out a comparative study on hydrocarbon potentials of two different reduction type humic coals in thd southern part of North china.The results show that humic coals of stronger reduction type have rich fluorescent vitrinite,stronger properties of vitrinite fluorescence,higher the atomic ratio of hydrogen to carbon,more chloroform bitumem and total hydrocarbon,higher oil potential of pyrolysis and more liquid hydrocarbon from thermal simulated experiment,especially Ro ranges from 0.6%to 0.9%.These charactoristics of stronger reduction type humic coals are quite different from those of weaker reduction tyep humic coals.All characteristics suggest that humic coals of stronger reduction type are relatively rich in hydrogen,and have higher hydrocarbon generation potentials,particularly for liquid hydrocarbon potentials.
