Abstract
A low mature coal (VRr=0.6%, from Manjia'er Depression, Tarim Basin, China in Jurassic system) was subjected to the closed system pyrolysis, in sealed gold tubes, under isothermal temperature conditions, ranging from 250 to 550 ℃ at temperature intervals of 50 ℃ (72 hours). The result shows that the biomarker compositions of the coal rock are dominated not only by mother matters, but also by coal mature and its lithology. This phenomenon is influenced by the intension of the different amount carbon biomarker, which was charged from mother matters of biomarker in generating hydrocarbon rocks at different evolution stages. At the same time, OEP cannot be regarded as a useful guideline of maturity in the thermal evolution of generating hydrocarbon rocks. The peak type of n alkenes presents two peaks in the whole evolution, in which the front peak is mainly mustered from nC 16 to nC 18, but the back peak is increasing while the simulated temperature rises. ΣC 21-/ΣC 22 + of coal rock shows regular changes with the temperature. The Pr/Ph ratio of coal rock falls when the temperature rises from 250℃to 550℃。
