Abstract: On the basis of organic geochemical analyses, a study was made on the abundance, type, thermal evolution characteristics and hydrocarbon generation history of terrestrial organic matter in the Lower Jurassic of Sichuan basin . The relationship between hydrocarbon generation, migration, accumulation and pool formation was investigated. It is proposed in this paper that the paleo-anticlines in the southwest of the source depression to be the major targets of future exploration.
