Interporosity flow function under unconventional fractured mode is essential to detailed numerical simulation of fractured reservoirs. The interporosity flow expressions between fracture and matrix under both heterogeneous and fractal geometric conditions have been put forward using analytical technique. The results show that the interporosity flow function newly established would be helpful to realize the detailed numerical simulation of fractured reservoir, and it has extensive applicability.
