Based on the geological features of bound water film with fixed thickness,the change law and controlling factors of fluids in reservoirs during forming period of the tight sandstone gas reservoirs were analyzed.Three geologic thresholds in the forming process of tight sandstone gas reservoir,including gas injection threshold,gas saturation threshold and gas termination threshold,were established.The corresponding concept model and calculation model were set up and used to predict the tight sandstone gas reservoirs in the Upper Palaeozoic of Ordos Basin.The results indicated that the correspondence depths of three geologic thresholds were 2 350 m,2 850 m and 4 800 m respectively.The liquid distribution characteristics predicted by using above geologic model are in good agreement with those of actual reservoirs,which indicates that this model can be used to accurately predict the liquid distribution in the tight sandstone gas reservoir.
