Saline aquifer storage is considered to be one of the main ways to realize CO2 geological sequestration. The purpose of the paper is to research CO2 and water seepage characteristics under the condition of different pressure and diameter of glass sand. First, establish four kinds of sand packed beds pore network model. Secondly, measuring the gas-liquid interfacial tension, contact angle under the condition of 50°C and different pressure (5-20MPa). Finally, using the two-phase flow model, obtain the gas-liquid two-phase relative permeability curves under different conditions. The simulation results of this paper can help to predict the actual saline aquifer storage of CO2 sequestration.

Dynamic Pore Network

We present in detail a set of algorithms for a dynamic pore-network model of immiscible two-phase flow in porous media to carry out fluid displacements in pores. The algorithms are universal for regular and irregular pore networks in two or three dimensions and can be applied to simulate both drainage displacements and steady-state flow. They execute the mixing of incoming fluids at the network nodes, then distribute them to the outgoing links and perform the coalescence of bubbles. Implementing these algorithms in a dynamic pore-network model, we reproduce some of the fundamental results of transient and steady-state two-phase flow in porous media. For drainage displacements, we show that the model can reproduce the flow patterns corresponding to viscous fingering, capillary fingering and stable displacement by varying the capillary number and viscosity ratio. For steady-state flow, we verify non-linear rheological properties and transition to linear Darcy behavior while increasing the flow rate. Finally we verify the relations between seepage velocities of two-phase flow in porous media considering both disordered regular networks and irregular networks reconstructed from real samples.
