Abstract
The possibility of decreasing the dimensions of the problem of two‐phase filtration in stratified beds through the introduction of modified phase permeabilities instead of the initial relative permeabilities (which are the coefficients of the initial system of equations within the framework of the Buckley–Leverett model) is investigated. Consideration is given to the physical and mathematical possibilities of constructing the modified permeabilities for the case where the relative permeabilities of each phase are presented by different analytical dependences for individual seams.
