用X射线衍射方法进行干酪根结构参数的测定

The Determination of Aromatic Degree of Kerogen by X-Ray Diffraction

本文探讨了用X光衍射技术,测干酪根芳香度的方法.测定了不同类型干路根及不同演化阶段煤干酪根的芳香度,并根据实验结果计算了晶胞参数,进而对其结构进行了讨论。实验结果表明,辽河油田不同演化阶段地质结构的干酪根中的芳香度随着成熟度的增高而增加其芳香片的实际数目增多。

In this paper, we have polled the method determining the aromatic degree of kerogen by X-ray diffraction. We have determined the aromatic degree of kerogen in different categories and kerogen in the coal of different evolutionary phases, and have calculated the cell parameters on the basis of experimental results. And then. We have discussed their structure. The experimental results representated that the aromatic degree of the kerogen from the geologic structure of different evolutionary phasesenlatges with the increasing of the grade of maturity, and so does it's number of aromatic sheets associated.
