Abstract: The fractured reservoirs with fracture network can be described with Kazemi model，Warren-Root model and De Swaan model，but the three models are not suitable for the reservoirs with locally developed fractures and without fracture network.Aiming at the feature that there exist local fractures in low permeable reservoir，by means of parallel-plane theory，tensor principle and equivalent flow resistance principle，the equivalent continuum media model of fracture-developed area is set up，on the basis of the model，3-D numerical simulation model for low permeability reservoir is established，and the black oil modeling program is used to conduct case study.Consequence shows that the equivalent media model can be applied to numerical simulation and dynamic prediction for the low permeability reservoir with local fractures.

Key words: fractured reservoir, low permeability, equivalent continuum media model, adaptability, numerical simulation
