摘      要：Enhancing oil recovery from clayey reservoirs is a significant challenge in petroleum industry due to complex interactions between fluids and rock surfaces,particularly clay *** study presents the first empirical analysis of magnetic fields impact on fluid flow in clayey porous *** core findings indicate that magnetic treatment of water increases oil recovery by an average of 15–30%in clayey media,with limited effectiveness in pure quartz *** experiments unraveled that improved recovery factor by magnetic treatment stem from both mitigated swelling and altered magnetic properties at clay surface;introducing 30%clay to porous medium decreased the recovery by 32%compared to pure quartz *** the clay to around 1000°C to reduce its swelling property improved the recovery by only 16%,suggesting magnetic treatment is not solely attributed to clay swelling *** ferromagnetic films at clay surface with HCl to produce non-magnetic FeCl_(3) resulted in a high recovery factor,similar to the clay-free ***,it was determined that a magnetic field intensity of 43760–51740 A/m is optimal for fluid displacement in clayey ***,the intensity of 47760 A/m increased recovery to 84.5%in a 30%clay medium,compared to 49.7%without ***,it was observed that the maximum flow rate was associated with zero potential difference across the medium,providing a faster method to determine the optimum magnetic field ***,the concept of‘Magnetic memory’was investigated,referring to the persistence of magnetic field s influence after its *** findings indicated that pressure build-up time stability lasted 10 days post-treatment,after which water behavior reverts,and clay swelling *** insight into the temporal dynamics of magnetic field application provides a deeper understanding of its long-term impacts on fluid flow in clayey reservoirs.
