In order to find out the reason of physical properties difference and to guide the development of oilfields in the study area,reservoir properties controlling factors of Shahejie Formation in Qinan fault step belt were studied on the basis of core observation,thin section analysis and lab experimental data. Results show that the reservoir space of the Shahejie Formation in Qinan Fault step belt is mainly of secondary denudation pore, and the Shahejie Formation belongs to medium porosity and low to medium permeability reservoir. The reservoir properties in the Es2 Formation are much better than Es1 and Es3 Formation. Sedimentation and diagenesis are main controlling factors of reservoir properties, the sedimentation determines the original property of the reservoir,and the diagenesis affects reservoir properties furtherly. Six controlling factors of reservoir physical properties are classified by means of clustering analysis, and the evaluation index was finally established. On this foundation, the reservoir types of Shahejie reservoir were classified and the reservoir distribution was also predicted. According to the evaluation result, the reservoir in the study area can be divided into four types. The Es2 Formation mainly developed Ⅰ and Ⅱ types of reservoir. Ⅲ and Ⅳ types of reservoir mainly developed in Es1, The reservoir type of Es3 Formation is mainly Ⅱ and Ⅲ types.
