Numerical Simulation of Time-Varying Characteristics in a High-Permeability Sandstone Reservoir: A Case of Gaoqian Southern Area
Table 6
Changes of reservoir wettability before and after water flooding.
| Lithofacies | Wettability before water flooding (wetting angle) | Wettability after water flooding (wetting angle) |
| Fine sandstone facies | Neutral (90°) | Strong hydrophilic (51°) | Middle sandstone facies | Neutral-weakly hydrophilic (82°) | Strong hydrophilic (43°) |
