In many applications, streamline simulation sh ows particular advantages over finitedifference simulation. By the advantages of streamline simulation such as its ability to display paths of fluid flow and acceleration factor in simulation, the description of flooding process gets more visual effect. The communication between wells and flooding area has been represented appropriately. In low permeability reservoirs horizontal wells have been applied to stimulate. And some horizontal wells have been fractured. But different fracturing methods are followed by different effects. Through streamline simulation this paper presents that the fractures improve both the productivity of horizontal well and the efficiency of the flooding unit. And the syntagmatic relation of distance between artificial fractures, fracture length and fracture conductivity has been given by orthogonal experiment. This method has been applied to the D160 reservoir in Daqing Oilfield. The production history of this reservoir is about 2 years. The reservoir is maintained above bubble point so the simulation meets the slight compressibility assumption. New horizontal wells are fractured followed from this rule.
