Research on the Mechanism of CO2-Oil Diffusion Impacting Oil and Gas Seepage Law in CCUS-EOR Process
Abstract In the process of enhanced oil recovery by CO2 huff and puff, the influence of gas diffusion effect cannot be ignored. In this paper, based on Fick's law and Buckley–Leverett equation, the fractional flow equation and the relative permeability model of oil and gas considering gas diffusion are established. The...
