Abstract:

The Upper Triassic reservoir in west Sichuan foreland basin has experienced normal compaction and ancompaction. Restored paleofluid dynamic field shows that Upper Triassic fluids premarily migrated towards lower fluid potential area and central Sichuan in the late stages of the Early and Late Jurassic;Jiangyou,Mianzhu,Xiaoqian,Sansuchang,Sumatou and Sandawan regions are favourable places for hydrocarbon accumulation.
