The carbonate condensate gas reservoir in North China features great burial depth and medium water invasion. It possesses complex development characteristics and percolation mechanism, leading to difficulties in parameter optimization of the storage capacity. The characteristics of the pore throat structure in the carbonate reservoir were studied based on the comparative analysis of capillary pressure curve and T2 spectrum in nuclear magnetic resonance. The gas-water two-phase percolation law in the micro-crack carbonate reservoir was analyzed by studying the gas-water two-phase relative permeability curve using non-steady state method. The results show that the carbonate condensate gas reservoir in North China has developed micro-fracture, narrow pore throat and concentrated distribution, the gas seepage characteristics vary in different layers, and all the factors have great influence on the construction and injection-production operation efficiency of gas storage. The characteristic evaluation provides theoretical basis for planning for construction and injection-production optimization.
