Embodiment Construction
[0009] The present invention will be described in detail below in conjunction with the examples.
[0010] The core samples used for the measurement were prepared in advance in accordance with the national petroleum and natural gas industry standard SY / T5913-2004 "rock slicing method" to make a light sheet (thickness 30 microns) and stick it on a glass slide. The following three spectral imaging methods were used respectively:
[0011] 1. Fluorescence microspectral imaging experiment: using a fluorescence microscope, when the light source is an ultra-high pressure mercury lamp, the excitation filter is configured as BG12 (2mm), and its central transmission wavelength is about 405nm, while the emission cut-off filter is configured For JB510, only fluorescence with a wavelength greater than 510nm can pass through. In order to facilitate the popularization of this method, the combination of the above two filters is selected for the higher fluorescence excitation and emission effic...
