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.
