摘要: Abstract CO2 foam was widely applied to enhance sweep efficiency through controlling gas breakthrough and channeling during the process of flooding. However, poor stability conventional system under harsh reservoir conditions restricted enhanced oil recovery (EOR) performance foam. Therefore, reinforced by anionic-nonionic surfactant SS163 regenerated cellulose (RC) developed; also its compared with other foams (e.g. stabilized SiO2, Al2O3, HPAM stabilizer-free foam). The static dynamic were evaluated modified Ross-Miles method, Warning Blender oscillation-shear-oscillation rheology. Furthermore, aging rules investigated via multiple light scattering method double-layer glass model. Upon that, stabilization mechanism RC proposed elucidated viscosity, storage loss modulus, morphological inspection, SEM images their correlation stability. results demonstrated that 1% SS163 + 1% has highest regeneration capacity foams. variations in film thickness diameter characterized four stages prolonged liquid drainage attributed following mechanisms: increased aggregates, ‘skeleton’ formed RC, effect RC. In this work, we introduce application EOR present unique on interface stabilizing capacity, viscoelasticity, thickened behavior sustainability highlights potential EOR.
