Abstract: Zhao 41 well area is the main gas producing area of tight sandstone of He 8 member in southeast Sulige Gas Field. However,the single well production is low and the productivity varies greatly. The petrological characteristics,diagenesis,physical properties,pore structure and seepage characteristics of reservoir were studied and evaluated by using data of cast thin sections,scanning electron microscope,cathodoluminescence,highpressure mercury injection,petrophysical analysis,nuclear magnetic resonance,gas-water relative permeability experiment and gas test,and the relationship between reservoirs type and natural gas productivity was discussed. The results show that the reservoir rocks of He 8 member in the study area are mainly lithic quartz sandstone,followed by lithic sandstone and a small amount of quartz sandstone,and the fillings is basically cements which are mainly illite,chlorite,kaolinite,siliceous and ferron calcite. Diagenesis is mainly compaction-pressure solution,cementation and dissolution,which has generally entered the stage B of middle diagenesis. The pore types are mainly secondary pores such as debris dissolved pores and intercrystalline pores,followed by residual intergranular pores,and the pore structure mainly consists of coarse pore-middle throat and fine pore-small throat. The saturation of movable fluid varies greatly,which is closely related to physical properties and increases with the improvement of physical properties. Based on the characteristics of reservoir physical properties,pore structure,sedimentary facies zone and sand body distribution,the reservoir of He 8 member in the study area was divided into four types. The productivity of natural gas is obviously controlled by reservoir types,and with the decline of reservoir type,the productivity of natural gas gradually decreases.

Key words: tight sandstone, reservoir characteristics, diagenesis, pore, Shihezi Formation, Ordos Basin
