| Abstract: | Aim By doing the qualitative and quantitative experimental study, the damage zone formation mechanism and the affecting factors of core flow efficiency were to be analyzed. Methods According to riddling gravel, the specific property of the rock was analyzed with the microscope. The NMR experiments were used for analyzing the characteristics of Berea Sandstone and the damaged zone. Results The core flow efficiency can be analyzed by the NMR experiments. Conclusion The porosity and core flow efficiency in the damaged zone are decreased, which seriously affects the flow efficiency of the oil Well. |
