By analyzing a great quantity of laboratory data, this paper studies the physical properties and pore structure of the sandstone reservoirs in the Permian Wutonggou formation. The reservoirs are of low porosity, moderate permeability and coarse throat. The reservoirs can be classified into 3 categories and 6 subdivisions according to the industrial standard. The sand beds of potential exploration are Types ⅠandⅡ of the 3rd category reservoirs. The control factors of physical property are mechanical compaction, sandstone grain diameter, and denudation. It is pointed out that 3000m of burial depth is a threshold, above which the reservoir physical properties are relatively preferable because of weak compaction.It is predicted that the high quality reservoir is mainly distributed in the slope zone from Ji No.7 well to Ji No.17 well.
