不同密度镜质组的热解色谱特征及生烃潜力的研究

ROCK-EVAL ANALYSIS AND HYDROCARBONGENERATING POTENTIAL OF VITRINITE GROUPS OF DIFFERENT DENSITIES

用热解色谱（Ｒｏｃｋ－Ｅｖａｌ）对２个褐煤样、３个气煤样的２８个分离组分进行了研究，揭示了不同密度镜质组组分之间生烃潜力具有较大的差异性；镜质组不仅可以作为重要的生气母质，而且还可以作为重要的生油母质。

Rock-Eval technique is used to study the hydrocarbon-generating potential of 28 separated macerals of different densities of five coals. There exists the obvious variation of hydrocarbon-generating potential among vitrinite groups. The vitrinite groups are not only the significant components for gas generation but also the important components for oil generation. The hydrocarbon-generating potential of coals mainly depends upon that of vitrinite groups.
