In general

fracturing well pattern is used for the development of low-permeability reservoir. This development process relates to the oil-water two phase flow

while the current researches on fracturing well productivity consider more about single phase flow. Based on the consideration of the reservoir anisotropy

threshold pressure gradient and oil-water two phase flow

a prediction method of fracturing well productivity is proposed by numerical method and sweep theory. And then

a contrast between the calculated results of the proposed method and field data is performed to verify the accuracy of the proposed model. The results show that when the water cut is constant

the increase of fracture conductivity results in the increase of the oil production. However

as the conductivity increases

the increase rate of the oil production decreases. The increase of the fracture conductivity also results in the increase of the cumulative oil production. When the conductivity is greater than 0.4 μm2·m

the cumulative oil production increases slowly. When the length of the fracture increases

the seepage resistance near the bottom decreases

so that the oil production increases. The increase of the permeability ratio indicates the planar heterogeneity becoming stronger

so that the productivity of the fractured well reduces showing a poorer water flooding effect. This study provides a theoretical basis for the optimization of the fracturing of the development well pattern by water flooding.
