NUMERICAL MODELING OF TWO-PHASE NONLINEAR FILTRATION PROCESSES BASED ON DIFFERENCE-ITERATION METHOD IN MOBILE GRIDS


The numerical simulation of the process of filtration of viscoplastic oil and water based on the difference-iteration method in mobile grids, taking into account capillary forces, relative phase permeabilities and phase compressibility is investigated. To study the effect of the aforementioned factors on the filtration process, a computational algorithm is developed.

Keywords: capillary forces, multiphase filtration, moving net, Darcy law, sweep method, quasi-linearization method, viscoplastic fluid, initial gradient
