Diagenesis of Volcanic Rocks and its Effects on Evolution of Reservoir Space of Yingcheng Formation in 2,3 Wellblock of Yaoshen Area
View through CrossRef
Based on a large number of core description, combined with indoor rock thin section analysis,cast thin-section pore character analysis ,microphotograph and scanning electron microscope observation, the diagenesis of the volcanic rock of Yingcheng formation in Yaoshen area were studied in detail. The results show that there are 5 kinds of diagenesis types in Yingcheng formation, among them, the dissolution, structure effect have a decisive influence on the formation of reservoir pore; reservoir space evolution has four stages in all, diagenesis has a great influence on reservoir space evolution.
