Pore-scale viscous fingering in porous media

WebJul 1, 2024 · Author(s): Xuanran Li (corresponding author) [1,*]; Jing Wei [2]; Lun Zhao [1]; Jun Ni [1]; Libing Fu [1]; Jincai Wang [1] 1. Introduction As one mechanism of chemical flooding, a high molecular polymer is added to a water solution to increase water viscosity and reduce water-oil mobility ratio, thereby inhibiting the fingering of the displacing phase … WebThis paper addresses simulation of non-isothermal water-oil displacements in porous media at pore-scale. The simulation approach was done by coupling Cahn–Hilliard phase field and heat equations using COMSOL Multiphysics. Finite element method with interfacial adaptive mesh refinement was employed to solve the equation system.
