| Abstract: | The pore have been classified structural types of the sandstone reservoir of the Paleogene Xinggouzui Formation in Jianghan Basin based on the analysis of mercury-injection, cast thin section, physical properties and oil testing production, in terms of the characteristics of mid-to-low porosity and permeability. The study has revealed the relationship between the pore structural types and oil production potential, and shown that the size of throat is the most important factor controlling the oil production potential of the sandstone reservoir. The study provides an important basis for reservoir evaluation. |
