| 摘 要： | 随着石油地球化学研究的深入,干酪根的研究也相应得到了发展。对于干酪根的研究,笔者从分离干酪根直至光谱分析,作了一系列的条件试验,同时,还作了模拟温度变化的试验。在这些试验的基础上,探讨了干酪根的结构与红外光谱之间的关系;对比国内外有关资料,提出了芳环波数位移律,用以研究干酪根的演化程度。另外,对干酪根分离过程中的有关问题,也进行了探讨。

| Abstract: | The main points in this paper are: 1. The influences of various ratios of pyrite, quartz, kaolin, and reagent treatments of NaBH4, HF, HCl on the IR spectra of kerogen are studied. 2. The IR spectrum data of pyrolysis simulation of kerogen are studied. 3. A synthetical appraise of the changes of 1700cm-1/1600cm-1, and 2900cm-1/2000cm-1 in IR spectra together with their significance and applicable range are made. 4. A new Index——The shifting rule of bands of aromatic ring is proposed. Along with the increase of the evolution of kerogen, the bands of aromatic ring skeleton vibration of 1600cm-1 shifts regularly toward low wavenumber.This Index is suitable for comparing highly mature kerogen. Therefore it has great significance in study of Paleozoic carbonate rocks which are widely spread in China. Meanwhile the method of wavenumber shift is meaningful in developing the application of infrared spectrophotometry in petroleum geochemistry. |
