作者根据煤中主要显微组份的反射率分布特征,对煤成烃作用和煤成油气生成期进行了评价.有机显微组份的光性演化与油气生成有着一定的相关性,它们的组合特征又可对油气生成期作出评价.本文对中国南方龙潭煤系南桐煤田的煤成烃进行了详细研究.

ksed on the distribution of reflectances of main macerals of coal,the formation of hydrocarbon in coal and the phases of coal-related hydrocarbon were evaluated.There is certain correlation between the evolution of optical character of organic maceral and the generation of oil and gas,and hydrocarbon-generating phases can be evaluated in terms of their composite characters. In this paper,the author detailed the coal-related hydrocarbon of the Longtan coal-bearing series of the Nantong Coal field, Southern China.
