Based on casting observation，SEM and X-ray diffraction，this paper studies the clastic reservoir characteristics of the 1st member of Wutonggou Formation，Beisantai Uplift，Junggar Basin and analyzes the controlling factors of the reservoir physical properties.The research shows that the sandstone reservoir of the 1st member of Wutonggou Formation mainly consists of volcanic rock debris with low compositional maturity and textural maturity.The reservoir was characterized by medium porosity，low permeability，medium pore volume and fine throat.The sedimentary facies is the main controlling factor in the study area，controls the transverse distribution of the reservoir physical properties.Compaction is the most important destructive diagenesis as well as the main factor that makes the reservoir physical properties worse.Cementation is the secondary factors that make the reservoirs physical properties worse.Dissolution is the main constructive factor that influences the reservoir physical properties in the study area.
