研究沉积岩中干酪根的类型和成熟度,对石油地质工作有着重要意义。我们用透射光和反射光偏光显微镜,并配合荧光显微镜和扫描电子显微镜,以松辽盆地南部白垩系下统青山口组干酪根为重点,研究了干酪根的形态、颜色、透明度、结构特征及荧光性等,并在这个基础上确定了干酪根的类型和成熟度。 Studying the type and maturity of kerogen in sedimentary rocks is of great significance to the work of petroleum geology. With the help of transmitted light and reflected light polarized light microscope and fluorescence microscopy and scanning electron microscopy, we focused on the kerogen kerogen in the Cretaceous Qingshankou Formation in southern Songliao Basin, and studied the morphology, color, transparency and structural features of kerogen. Fluorescence and so on, and on this basis to determine the type and maturity of kerogen.
