Abstract

After prolonged production, the inter-layer heterogeneity of reservoirs increases. To enhance the utilization of low-permeability layers and improve overall reservoir recovery, this study employed sand-pack models with multiple measurement points and varying permeability, which were connected in parallel to more realistically simulate inter-layer heterogeneity. Plugging efficiency evaluation experiments and oil displacement experiments were conducted. The results demonstrated that, among a gel dispersion, microspheres, and PEG, the gel dispersion exhibited the highest plugging efficiency, reaching 86.57%. The optimized injection parameters for the gel dispersion were found to be a weight percentage of 5%, an injection volume of 0.25 PV, and a single injection round. The recovery rate can be increased by 34.68%. This achieved the optimal profile control for heterogeneous reservoirs and provided a valuable reference for oilfield development.
