Gas Generation Experimental Research of Shales, Coal, Bitumen and Oil

Gas generation simulated experiments of the satand samples of shale (marine and oil shale), coal, bitumen and oil are performed in the closed system. Gas yield, peak stage and molecular composition of the different precursors in different thermal maturation stages. The gas generation mechanism and regulations of different precursors and the influence of precursor types and the thermal maturation degree are researched. The results of this paper provide the experimental basis to the indentification of the effective source rocks.
