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
