Pore fluids in basins control the migration of material and energy in sedimentary basin. Make sure pore fluids evolution process would be important for high-quality reservoir prediction. In this study, we pay attention on Dongying sag, which located in the eastern of Jiyang depression, Bohai Bay basin. We collected core sample for thin section observation and SEM, to determine diagenetic sequence in sandstone of study area. Take geological characteristics of study area into consideration, make sure the source of diagenetic products. At last, we deduce the pore fluids evolution process in study area.
