| 摘 要： | 根据热解实验和动力学模拟计算结果,研究了塔里木盆地库车坳陷侏罗纪煤、煤系泥岩及三叠纪泥岩的生气特征与生气模式。结果表明,库车坳陷三叠-侏罗纪烃源岩具有良好的生气性,尤其在进入中、高热演化阶段,甲烷产率更高,且侏罗纪煤和煤系泥岩的甲烷产率要高于三叠纪泥岩。侏罗纪和三叠纪烃源岩均以生气为主,是库车坳陷的有效气源岩,但前者的生气贡献明显高于后者。

| Abstract: | Based on the results of pyrolysis experiment and kinetic modelling calculation,the characteristics and models of gaseous hydrocarbon generation from Jurassic coals,Jurassic mudstones and Triassic mudstones in Kuqa Depression were studied in this paper.It is shown that the Triassic-Jurassic source rocks in Kuqa Depression have good potential of gaseous hydrocarbons generation,which produce high methane yields at the medium-high thermal evolutionary stage.The gas yields generated from Jurassic coals and Jurassic mudstones are higher than those of Triassic mudstones. It is suggested that both Jurassic source rocks and Triassic source rocks are the effective gas source rocks in Kuqa Depression.But,the contribution to gas generation from Jurassic source rocks is obviously larger than that of Triassic source rocks. |
