For the study of charge history and distribution law of oil and gas in the Dabei 1 tight gas reservoir in the Kuqa Depression of the Tarim Basin, 36 sandstone samples collected from wells DB 101, DB 103 and DB 2 were tested with quantitative grain fluorescence techniques. The results showed that wells DB 101 and DB 2 located in the same palaeo-trap while well DB 103 located in a separate palaeo-trap. Oils distributed in layers in those traps. The present water layers in well DB 101 were palaeo-hydrocarbon migration paths. Under the current gas-water interface in well DB 103, there might be residual oil layers. Part of the palaeo-oil reservoir in well DB 2 was destroyed in later stage.
