摘要
对六种典型烃源岩的显微荧光变化做了系统研究,提出了不同显微组分荧光变化的六种基本形式和一套定量参数,讨论了荧光变化在研究源岩成熟度、差异成熟作用和烃类微运移聚集等方面的实际应用。
In this paper, the synthetic studies on microfluorescence alteration regularity during30 minites irradiation have been made for more than 100 typical hydrocarbon sourcerocks. Starting with the two types of organic matter (kerogen and soluble organicmatter) which lead to fluorescence and are composed of macerals, the authors discussedsome geological factors effecting the fluorescence alteration, including maturity, the typeof macerals and the abundance of organic matter, and proposed to use four parameterssuch as fluorescence alteration gradient (P), turning time (T), equilibrium intensity ratio(I_R) and the difference of spectral maximun wavelength (Δλ_(max)) to describe the fluores-cence alteration. It is suggested that the fluorescence alteration of source rocks can not on-ly indicate their maturation level, but also provides informations about oil generation, mi-gration and accumulation.
