摘要：

南堡凹陷东营组及沙河街组烃源岩的富氢显微组分随着热演化程度的增加,荧光光谱峰波长λmax值增加,红绿光相对强度比值增大,荧光强度I546降低,且均在埋深3400m左右出现阶段性变化。因此,可以确定南堡凹陷烃源岩的生油门限深度在3400m左右。

关键词: 显微组分, 烃源岩, 荧光光谱, 生烃门限, 南堡凹陷

Abstract:

As the thermal evolution degree of hydrogen rich macerals in source rocks of Dongying and Shahejie Formations in Nanpu Sag increases,the wave peak λmax of its fluorescence spectrum will increase,the relative intensity of red light and green light will increase and fluorescence intensity will decrease and periodic changes would occur in 3400 m depth.It thus suggests that the oil-forming threshold of Nanpu Sag is±3400 m.

Key words: macerals, hydrocarbon source rock, fluorescence spectrum, oil threshold, Nanpu Sag
