Natural fractured reservoirs exist widely in the world. The heterogeneous porous medium was idealized to be a uniform system of the fracture and matrix for the convenience of numerical simulation. The traditional method to describe the flow exchange between the matrix and fracture is using a function related to shape factor and the pressure difference between the matrix and fracture. However, this classical model cannot be applied for the incompressible fluid. A new exchange flow computational method between matrix and fractures of quasi-one-dimensional flow in fractured reservoirs is proposed in this article. Numerical simulations are performed to demonstrate that the proposed method can provide more accurate results.
