摘要: 本文采用快速热模拟实验方法,对菌解无定形体D和微粒体B含量达到76.50%~93.88%的干酪根样品进行热模拟实验,并着重讨论其热演化生烃规律及对成烃的贡献。实验结果表明,菌解无定形体D的液体烃产率较高,微粒体B的气体烃产率最大。所有实验样品的产烃峰期均发生在Ro值相当于0.70%~1.00%时,产气峰期略滞后,Ro值约为0.8%~1.00%.烃类组分为C1-C17,因此菌解无定形体和微粒体B是形成天然气和凝析油的重要显微组分之一。Abstract: By the method of the Rapid Thermal Simulation Experiment,kerogen samples with the D-bacteriodecomposed amorphous solid and B-micrinite contents of 76.50%-93.88% are conducted the experiment.And their hydrocarbon-generating mechanism of thermal evolution and their contribution to hydrocarbon formation are discussed in particular.Experimental results reveal that D-bacteriodecomposed amorphous solid has higher liquid-hydrocarbon producibility and B-micrinite has maximum gas-hydrocarbon producibility.The peak period of hydrocarbon generation for all the experimental samples occurs at the R0 value of 0.70%-1.00%,and the peak period of gas-hydrocarbon generation slightly lags with the R0 value of 0.80%-1.00%.As the hydrocarbon components include C1-C17,hacteriodecomposed amorphous solid and B-micrinite are some major macerals to form natural gas and condensate.
