Abstract:
The article describes a physical and mathematical model of steady-state flow of oil and
water mixture in the pore space of a core, represented as a set of capillary clusters. The
developed technique allows to calculate the functions of relative phase permeabilities
based on the data of standard laboratory core analysis and experiments on single-phase
fluid filtration. As a result of regression analysis of laboratory data on terrigenous rocks
of Western and Eastern Siberia oil and gas fields, multi-parameter dependences of the parameters of the interfacial interaction function on reservoir properties and parameters of
the capillary cluster were obtained. It has been established that the results of relative
phase permeability calculation using the proposed computational-experimental method
are in good agreement with the experimental data.
