Based on the Pore Network Model of CO₂-Water-Quartz System Two-Phase Flow Characteristics Study

Abstract:

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.
