Based on field crop, core and thin section analysis, the influence of diagenesis on the beach reservoirs in Feixianguan Formation, PuguangGas Field was synthetically studied. Bymeans of studying the relationship of reservoir space and diageneses in a variety of diagenetic environments, the diageneses can be divided into destructive diagenesis (cementation) and constructive diagenesis(dolomitization and dissolution). The primary pores and part of the secondary pores in beach reservoirs disappeared after cementation. While mixing water dolomitization and burial dissolution which play a significant influence on the development of secondary pores in beach reservoirs, can form reservoir spaces such as intragranular pores,intergranular pores and intercrystal pores.
