ABSTRACT = {Simulation of fluid flow in the fractured porous media is very important and
challenging. Researchers have developed some models for fractured porous media. With
the development of related research in recent years, the prospect of embedded discrete fracture model (EDFM) is more and more bright. However, 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 resources. To address this challenge, in the present paper, an upscaling
based model is proposed. In 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. The 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.},
