| Abstract: | To improve the numerical simulation calculation speed for steam assisted gravity drainage(SAGD) process in fracture-pore dual-porosity reservoirs,the adaptive mesh refinement(AMR) algorithm as well as the fracture-matrix equation decomposition approach under a dual-porosity(DK) model was proposed by using different grid sizes in different regions based upon the spatial variations of the temperature and phase-saturations.The numerical results show that the proposed AMR technique dealing with such nonlinear p... |
