摘要
根据煤层气体具有富苯和贫正己烷的特征,提出了“苯指数”(B)和“正己烷指数”(H)两项判别煤层气的指标。对于反映煤层气体的富烃程度和有机质成熟度而言,指标H的规律性更明显。此外,对煤在不同演化阶段苯蒸气的成因进行了探讨。
Based on the characteristics that in coal bed gas exist rich benzene and poor N-hexane, the authors propose two indicators as“Benzene lndex”(B)and“N-hexane lndex”(H)to distinguish the coal bed gas. The regularity of indicator H is clearer to reflect the level of rich-hydrocarbon of coal be gas and the maturity of organic matter, In addition, the origin of the benzene vapor in various evolution stages of coal is discussed also.
