Horizontal wells with large-scale hydraulic fracturing is required for the effective development of the tight oil reservoirs due to extra-low permeability. After fracturing，there exists two porous media with quite different percolation laws，that is matrix and fracture. A new production analysis model is needed to meet the demand of dynamic analysis of fractured horizontal wells in the tight oil reservoirs. Based on the different percolation laws of the matrix and fracture in the tight oil reservoirs，a coupled production model of a multi-stage fractured horizontal well in the dual-media formation is proposed and solved by using finite volume method on the basis of unstructured hybrid grids. Meanwhile，the typical Blasingame curve of the fractured horizontal well in the tight oil reservoirs is obtained，and the characteristics of the Blasingame curve are analyzed. The development stages of the fractured horizontal well can be divided into three stages：fracture linear flow， boundary-dominated flow and transition flow. The threshold pressure gradient，fracture numbers，fracture spacing and fracture length have major effects on the Blasingame curve. Blasingame curve moves down linearly with the increase of threshold pressure gradient in the later stage of boundary-dominated flow，and disperses upward with the increase of fracture numbers in the early and middle stages，and moves up with the increase of fracture spacing and fracture length in the middle transitional flow stage，but the effect of fracture spacing on the Blasingame curves is more significant.
