%X In this paper, an integrated micropore-scale to core-scale modeling method is proposed to capture both the different scale pore structures and multiphase flow properties in carbonate rocks. The first upscaling is at submicrometer to micrometer scale. The micropore-scale upscaling is accounted for through the micropore network model, which is extracted through three-dimensional micropore digital rocks based on two-dimensional high-resolution carbonate images and could describe the geometric and hydraulic properties of micropores. The second upscaling is in the tens to hundreds of micrometers scale. The macropore-scale upscaling is described through a dual-pore network, which is constructed based on the integration of macropore and micropore networks and could describe the macro- and micropore characteristics simultaneously. The last upscaling is at millimeter to centimeter scale. Core-scale upscaling is described by a capillary equilibrium method, which could produce the integrated relative permeability curve of whole core plug. This integrated upscaling method could capture the detailed micro- and macropore structures in carbonate rock and then upscaling the relative permeability curve to the core scale, which could be used for large-scale grid calculations of carbonate reservoir simulations.
