Abstract: Pore-scale network model represents the genuine pores and throats with simplified geometry objects, to analyze the flow in which is of great importance. Firstly the finite element method is used to solve the velocity field which is then used to calculate hydraulic conductance. The relation between hydraulic conductance and shape factor is researched. As for the single phase flow, the result shows that the hydraulic conductance is nearly linear to shape factor. While with respect to two phase flow, it also changes with half corner angle and oil-water contact angle.

Key words: hydraulic conductance, shape factor, pore-scale network model, finite element method, triangular capillary
