Gas Generation Regularities of Dissipated Soluble Organic Matter in Sichuan Basin

Abstract:

The organic matter of marine strata has high degree of thermal evolution in Sichuan Basin. The gas generation ability of kerogen is very limited, which mainly relies on the soluble organic matter as gas parent material to provide gas source for gas reservoir. In this paper, chemical kinetics method and experiments are applied to study on the history of gas generation and gas generation rate of organic matter in Sichuan marine strata. Result shows that dissipated soluble organic matter in source rocks, dissipated soluble organic matter out of source rocks and organic matter in paleo-reservoir successively generate gas in proper order. Dissipated soluble organic matter out of source rocks and the oil in paleo-reservoir belong to late gas generation.
