The Shuixigou group of Jurassic in Tu-Ha Basin has geologic conditions for forming large tight sandstone gas reservoir. Long-term and great amount gaseous hydrocarbon generation and expulsion provide preconditions for forming tight sandstone gas reservoir. The source rocks and reservoir rocks appear in interbedded contact relations which are favorable for inter-source gas accumulation in the tight sandstone reservoir. The gas migration and accumulation in the tight sandstone reservoir are quite different from those in conventional gas reservoir.
