Carbonate rocks have well-developed macropore and micropore systems, it is necessary to study the dual pore characteristics in carbonate rocks. In this paper, based on the original macropore network and micropore network, a stochastic upscaling method is used to build the dual pore network with the integration of macropores and micropores properties in carbonates together and upscale the dual pore network to a larger scale. This method is verified by geometry-topology and flow parameters comparison, which provides an important tool to microscopic flow research in carbonate media.
