主 题：Dual embedded discrete fracture model(D-EDFM) local upscaling fractured
摘 要：Simulation of fluid flow in the fractured porous media is very important and *** have developed some models for fractured porous *** the development of related research in recent years,the prospect of embedded discrete fracture model(EDFM)is more and more ***,since the size of the fractures in the actual reservoir varies greatly,a very fine grid should be used which leads to a huge burden to the computing *** address this challenge,in the present paper,an upscaling based model is *** this model,the flow in large-scale fractures is directly described by the EDFM while that in the small-scale fractures is upscaled through local simulation by *** EDFM is used to simulate the large-and small-scale fractures independently two times,so the new model is called dual embedded discrete fracture model(D-EDFM).In this paper,the detailed implementation process of D-EDFM is introduced and,through test cases,it is found the proposed model is a feasible method to simulate the flow in fractured porous media.
