Pore-scale remediation investigation of oil-contaminated soil is important in several environmental and industrial applications, such as quick responses to sudden accidents. This work aims investigate the oil pollutant removal process optimize performance at pore scale find underlying mechanisms for from soil. The conservative forms phase-field model non-Newtonian power-law fluid are employed track moving interface between two immiscible phases, flushing pores investigated. effects viscosity, interfacial tension, wettability, velocity on pore-scale regularity explored. Then, agents (surfactant system surfactant–polymer system) compared using an content prediction curve based UV-Visible transmittance. results show that optimal efficiency obtained a weak water-wetting with contact angle 60° due stronger two-phase interaction, deeper penetration, more effective entrainment flow. On basis dimensionless analysis, relatively larger velocity, resulting higher capillary number (Ca) certain range, can achieve rapid efficient removal. In addition, appropriately low rather than ultra-low intension, contributes strengthening behavior. A reasonably high viscosity ratio (M) state plays synergetic roles contaminated agent combined surfactant polymer remarkably enhance sole use surfactant, achieving 2.5-fold increase efficiency. provides new insights into often-overlooked dynamics behind via injection, which fundamental importance development response strategies contamination.
