Abstract:

In this paper, the synthetic studies on microfluorescence alteration regularity during 30 minites irradiation have been made for more than 100 typical hydrocarbon source rocks. Starting with the two types of organic matter (kerogen and soluble organic matter) which lead to fluorescence and are composed of macerals, the authors discussed some geological factors effecting the fluorescence alteration, including maturity, the type of macerals and the abundance of organic matter, and proposed to use four parameters such as fluorescence alteration gradient (P), turning time (T), equilibrium intensity ratio (IR) and the difference of spectral maximun wavelength (Δλmax) to describe the fluorescence alteration. It is suggested that the fluorescence alteration of source rocks can not only indicate their maturation level, but also provides informations about oil generation, migration and accumulation.
