... radius due to particle retention and plugging, thus intensifying the heterogeneity. Ultimately, by displacing the rock samples at a flow rate of 6 ml/min to 1000 PV, the median pore-throat radius increased by 20% to 70%. In Class III reservoirs, by displacing the rock samples at a flow rate of 4 ml/min...

... of permeability, porosity, fracture half-length, and fracturing fluid hydraulic on shut-in time. The results show that during the well shut-in period following hydraulic fracturing, oil and water in the matrix and fractures undergo imbibition displacement. If the shut-in time is too short, the oil-water...
