Based on the analysis of ordinary thin sections, cast thin sections, scanning electron microscope and X-ray diffraction, this paper studied the diagenesis types, evolutionary phase, evolutionary series and influencing factors of reservoir properties of E1+2 and E31 in Qie 6 well area ofKunbei Oilfield. The result shows that the sandstone of E1+2 and E31is in the late stage of middle diagenetic stage A, and the main diagenesis types are compaction, cementation, dissolution, metasomatism and cataclasis. The experienced compaction, quartz secondary enlargement and cementation of calcite and anhydrite are the main destructive factors of reservoir properties, while the dissolution of feldspar, detritus and calcite and cataclasis are the constructive factors of reservoir properties.1
