| 1 | Inpouring polymer flooding is one important process to enhance oil recovery. | |
| 2 | These fractures play an important role in controlling fluid flow and recovery. | |
| 3 | To enhance recovery ratio, it is necessary to have a better understand on the micro-heterogeneity of reservoir. | |
| 4 | In according with this principle, the separating efficiency should be the product of recovery of each objective minerals separated in the products. | |
| 5 | From the research of quasi ?relative permeability curve in black liquor system, we can see that higher recovery factor can be obtained by black l. |
