The research results are highly reproducible owing to the repeatable micro-model technique.(2) Quantifying the Kr-S-P curves in two-phase flow. The validity and adaptability of multi-phase curves are verified using micro-model testing bed tailored to adequate scale of pores. Results obtained from the P-S micro-model tests generally agree with the threshold values of displacement mechanism offered by researchers using geometric shapes. The hysteresis of .experimental Kr-S curves of numerous two-phase flows are depicted in terms of connectivity and humidification. The P-S and Kr-S curves of two-phase flow are well-derived in conjunction with micro-model test results and empirical van Genuchten model. For the curve expressing the relation between saturation and capillary pressure, experimental results of water-air flow system corresponds to the theoretical data.
