Experiment results of different injection-production patterns of samples.
| | Sample number | Permeability (10−3 μm2) | Porosity (%) | Injection-production patterns | Anhydrous recovery degree (%) | Residual oil saturation (%) | Final recovery degree (%) |
| | (I) | 6.061 | 23.05 | Co-in | 23.10 | 25.27 | 55.68 | | (II) | 7.659 | 24.48 | Si-in | 20.00 | 43.78 | 36.38 | | (III) | 15.491 | 20.53 | Co-in | 7.11 | 47.04 | 34.78 | | (IV) | 19.447 | 14.52 | Si-in | 12.39 | 31.76 | 58.00 |
