Effects of thin meander dot dam inter-bed on efficiency and distribution of CO2 injection flow

In this paper, we build one new coupled CO₂ injection model DBNSC (Darcy-Brinkman-Navier-Stokes Carbon Dioxide Injection Model) near well opening based on Navier-Stokes equation Brinkman equation and Darcy equation to simulate the effects of thin meander dot dam inter-beds on efficiency and distribution of CO₂ injection. CO₂ injection flow moves through perforation and a thin porous layer towards the far field from the well. The fluid flow follows Darcy´s law in the far field and Brinkman equation near the well opening, the Navier-Stokes law in the well. For simplicity, in this paper, we assume the layer between well and far field has homogeneous and isotropic hydraulic properties, and the fluid has constant density. The new model triggers weak variables to implement the coupling between Darcy´s law and the Brinkman equations. This paper reviews the results and outlines of the mechanics for building this model.
