Productivity equation of multi-fractured horizontal well pattern in Fractured low permeability reservoirs
Based on fractal theory to characterize the complex fracture morphology of natural fractures and fractured fracture networks,a nonlinear seepage model for fractured horizontal and vertical well groups in fractured low-permeability reservoirs was established,targeting the nonlinear seepage characteristics and reservoir pressure sensitivity of fractured low-permeability reservoirs.Based on the different flow patterns of fluids in a mixed well network,it is divided into three regions and the coupled productivity formula of the mixed well network is derived.The influence of parameters such as fractal dimension,pressure sensitivity effect,and fracture length on the productivity of the well network is analyzed.
