The only major breakthrough in the exploration of the Sinian of the Sichuan Basin has been track simulation was applied to constrain the thermal evolutionary history of the source rocks in this study. Combined with trap formation and evolution, the formation, destruction, and accumulation history of the Sinian reservoirs were analyzed from a dynamic perspective. The Sinian reservoirs underwent several primary stages: the paleo-reservoir formation and destruction in the late Silurian, hydrocarbon Jurassic, and the exsolution and accumulation of dissolved-gas as a result of episodic uplift since the Late gas. The formation of the Weiyuan gas field is also related to this process. The Sinian in the Sichuan Basin has a broad exploration prospect, and exploration targets focused on the Leshan-Longnüsi Paleotransformation.
