| Abstract: | In view of five-spot water-injection pattern in low permeability reservoits, this paper studies the effect of fracture parameters and orientation in an integral fracturing on oil recov-ery by using reservoir simulation. With this simulation, we introduce a model-building andsolving method which incorporates matrix and fracture into one system, By calculation of oilfield examples and in comparison with the results from literatures , this model has beenproven to be effective. |
