| Abstract: | The research is based on the collected data including properties, electron microscopy scanning and physi- cal property analysis to discuss the petrologic feature, physical property and diagenesis in order to divide diagenetic facies and point out the favorable ones of Upper Paleozoic S~ formation in north Zizhou gas field. There are 6 diage- netic facies zones with variousgenetic types in the study area, of which inter - grain pores ＋ weak quartz overgrowth cemented and corroded diagenetic facies and kaolinite ＋ quartz overgrowth cemented and weak corroded diagenetic facies are the most favorable diagenetic facies. Hydromica cemented and metasomed micropore diagenetic facies, calcareous cemented and metasomed compact diagenetic facies and siliceous cemented compact diagenetic facies are adverse diagenetic facies. Kaolinite ＋ quartz overgrowth cemented and inter - grain pores ＋ weak quartz overgrowth cemented and corroded diagenetic facies are favorable diagenetic facies that most developed in study area which di- recting further gas exploration. |
