Fluid inclusions are resulted from the interaction between water and rocks in petroleum systems, and they record the information of the fluid generation, migration and evolution of a basin. The authors carried out an investigation on the type, distribution characteristics, homogenization temperature, salinity and composition of fluid inclusions in late Triassic clastic rocks in the Pingluoba, Qiongxi and Baimamiao gas fields in the southern part of the west Sichuan foreland basin. Some samples were analyzed using laser Raman spectroscopy. And in combination with the buried history and the maturity history of the source rock, the hydrocarbon accumulation process of the second member gas reservoir of Xujiahe Formation in the basin. The second member gas reservoir experienced a continuous process of formation: small charge in the Indonesian period, large charge in the Yanshan period, and adjustment and small charge again in the Himalayan period. The main charge time is 195~95 Ma. The research is very important to reorganize the gas reservoir geology characteristics, hydrocarbon accumulation rules and to make exploration strategies.
