本文应用X射线衍射法测定干酪根的芳香度,并根据X射线衍射谱图计算干酪根的微晶参数,以研究干酪根的结构。研究表明,芳香度与干酪根的类型有关,与干酪根的H/C原子比有良好的相关性;微晶参数与干酪根的演化程度有关,成熟度越高微晶参数值也越高。为干酪根类型的研究和成熟度的划分提供了新的线索和途径。

In this paper, the texture of kerogen is studied, using x-ray diffraction to determine the aromaticity of kerogen.According to the x-ray diffraction spectra, the microcrystalline parameter of the kerogen is calculated. The study indicates that the aromaticity is related to the types of kerogen, and keeps good relationship with the H/C atomic ratio of kerogen. The microcrystalline parameter bears a direct relationship to the evolutionary level of the kerogen, i.e. the higher the maturity, the higher the value of the microcrystalline parameter. Thus, it opens a new way for the study on kerogen.
