摘要：
The process where oil can be displaced by the water via capillary imbibition is studied. The model, q≡q1+q2 = 0, is considered. The classical porous medium equation (PME) is obtained in this process, represented by the equation &parttv-Δφ(v) = 0 (1), where φ(s) = -1/ρ∫0s f1(ξ)f2(ξ)/f1(ξ)+f2(ξ) J′(ξ)dξ.
