Optimization of Integral Fracturing Parameters for L Zone of Low Permeability Reservior

Commercial oil flow can be acquired by fracturing for low permeability field.But recovery would be falling because of unreasonable fractural length.Consequently reasonable fracturing parameters play an important role to low permeability development.To the character of L zone,firstly heterogeneous geology model be established to research the effect of fracturing parameters on reservoir performance.The range of parameters can be obtained.Secondly,integral fracturing schemes could be designed by orthogonal optimization and optimized by fuzzy mathematics.Finally,fracturing parameters would be inspected by history matching.Results suggest by research that there are optimal values for fracturing parameters.The fracturing length of edge well is about 100 m,the fracturing length of corner well is about 120 m,and flow conductivity is 25 μm2·cm.
