Experimental studying of influence of scale effects on characteristics of a two-phase filtration

Authors: N.N. Mikhaylov (Gubkin Russian State University of Oil and Gas, RF, Moscow), I.P. Gurbatova (PermNIPIneft Branch of LUKOIL-Engineering LLC in Perm, RF, Perm)

Key words: two-phase filtration, relative rock permeability, scale effect.

Influence of large-scale effects on relative phase permeability is experimentally studied. It is established that manifestation of scale effect is caused by distinction of microstructures in samples of the various size. Characteristics of influence of scale effects on function of relative permeability are shown.
