A Seepage Model for Fractured Low Permeability Reservoir
For fractured low-permeability sandstone reservoir,it is very difficult to use the conventionalmethod to handle the stochastically distributed natural fractures．which do not connected with the wells,in the theoretical study of the naturally fractured reservoir. To study the seepage law of the fracturedreservoir,a fractured heterogeneity composite reservoir seepage flow model is proposed by using theequivalent flowing resistance method．With this model,the effects of natural fracture parameters onproductivity and formation pressure were investigated. The results indicate that the fractures within 10mto the wellbore will have great impacts on pressure distilbution and productivity;and the impacts offracture length．fracture aperture and fracture number on pressure distribution and productivity willdecrease after they are greater than some certain value. The study clarified theoretically the reason thatfractures improve the productivity．
