Based on integration of thin section, X-ray diffraction analysis, scanning electron microscopy, cathodolumi-nescence and mercury injection, we found out that the Permian reservoir under the Kebai fault in the northwestern margin, Junggar basin was formed in the alluvial fan and fan-delta facies. They were comprised of sandy glutenite, glutenite, and pebbled sandstone. During the diagenesis, the rock assemblages went through compaction, cementation and corrosion. The types of the reservoir pore are primary intergranular pore, intracrystalline pore, carbonate cement and zeolite dissolution pore, and micro fractures formed under tectonic action. The reservoir is in the stage B of late diagenesis, most primary pores were destructed after the diagenetic evolution and the secondary pores were mainly formed. Therefore, the diagenesis would control the physical properties of reservoir in this area. Porosity evolution greatly experienced the three phases, including destruction of primary pores, formation of secondary pores and destruction of secondary pores.
