Resonance-Enhanced Pulsing Water Injection for Improved Oil Recovery: Micromodel Experiments and Analysis

Enhanced oil recovery (EOR) is a crucial technology in the petroleum industry, influenced by several factors, including flooding fluids and methods. The adjustment of injection strategies application vibration stimulation can significantly impact recovery, especially residual oil. In this study, we conducted experiments using glass micromodel to investigate effect pulsing water on recovery. Our results show that when pulse frequency matches natural micromodel, resonance occurs during two-phase flow driving, which causes an increase amplitude oscillation, enhances mobility oil, improves efficiency kinetic energy displacement also improved. However, 3 Hz, absence leads opposite effect. addition, found greater increases fluidity These findings have significant implications for design EOR experimental provide insight into offer potential strategy optimization techniques.
