Study on Long-Core Experiment of Gas Driving in Dual-Media Reservoir

Abstract:

Reservoir X is a fractured-porous dual-media reservoir. According to the geological conditions and exploration and development statuses of reservoir X, this paper designs a long-core experiment and then carries it on. As a result, the diffe_{Subscript text}rent enhance displacement efficiency effects under different driving methods (water flooding, gas flooding, WAG, pulsed gas injection, gas slug flooding) and different driving media (flue gas, CO₂) are obtained. The results show that among all those driving methods, water alternating CO₂ injection (WAG) reaches the best effect. WAG has an injection rate of 0.8HCPV and enhances displacement efficiency by 26.93% on the basis of water flooding. The injection rate of gas slug/water flooding after CO₂ slug flooding is 0.3HCPV and these two methods have similar good results, 13.66% and 13.95% respectively. So considering the economic factor, we draw a conclusion that water flooding after CO₂ slug flooding is the optimum choice.
