高（过）成熟干酪根结构的TEM研究

TEM STUDY OF THE TEXTURE OF HIGHI-Y/OVER-MATURED KEROGENS

应用ＴＥＭ的高分辨率、高放大倍数及选区电子衍射和暗场技术，对高（过）成熟干酪根的形态、生物次要相及质点的分子走向延展度进行系统详细的对照分析，提出了一套鉴定规则，为鉴定高（过）成熟干酪根类型找到了第一性可靠的依据。

Taking the advantages of the TEM (Transmission Electron Microscope), such as the high resolution and high amplification coefficient, and the electron diffraction and dark field method in the selected area, etc., the morphology, biosubfacies and the oriented molecular elongation of a mass point of the highly/over-matured kerogen samples were systematically analysed in detail. Then, the methods concerning the identification the highly/over-matures kerogen types by using the TEM were suggested.
