Abstract

In order to determine the optimum design of the fracture parameters for tight gas reservoirs,effective permeability was introduced to modify the conventional proppant number considering the impact of non-Darcy effects on fracture permeability and conductivity.The boundary element method was used to make a chart which represented the relationship among the non-dimensional gas productivity index,the proppant number and the effective fracture conductivity,and then obtained an equation of f function.Next,the optimal parameters and conductivity of the fracture network were obtained through iterations of the algorithm,and formed an optimization method of fracture parameter in tight gas reservoir which considered non-Darcy effect and taken gas productivity as objective function.The data of tight gas reservoir in Sulige block was used to analyze the impact of non-Darcy effect on the optimization of fracture parameters.The results showed that,when considering non-Darcy effect,the proppant number was 20 percent of that without considering it,and the effective fracture conductivity was 33 percent,the optimal fracture length was reduced by 20 percent,and the width of fracture increased by 25 percent.In conclusion,the optimal design of tight gas reservoir fracture parameter can be calculated by revising the proppant number,which resulted in shorter and wider.
