     Due to bimodal pore size distribution of carbonate rocks,macro pore network and micro pore network are produced to describe different pore characteristics separately,and carbonate dual pore network is constructed with the coupling of macro pore and micro pore network.Then primary drainage and secondary imbibition process are simulated based on intrusion-percolation theory during the oil-water two phase fluid flow,the capillary pressure and relative permeability model are calculated.At last,the influence of reservoir parameters on relative permeability curve is studied under water-wet conditions by adjusting the network structure parameters.Results show that oil relative permeability curve rises with the increase of micro pore density factor and average coordination number,and oil and water relative permeability curve drops with the increase of dual pore radius ratio.These phenomena are important to the study of carbonate reservoir microscopic flow mechanism.
