An expert system for economic optimization of hydraulic fracturing design was established preliminarily.The key point of the expert system is the utilization of genetic algorithm in the economic optimization of fracturing design.With the genetic algorithm,the optimized design of fracturing plan can be selected from more than one hundred candidates generated by random function.Then,the reproducing and mutating processes were performed on the data of above candidates.Finally,the optimized parameters for hydraulic fracturing design plan can be obtained.Furthermore,the fluctuation range of oil price and interest rate may also be taken into account.Therefore,the new model put forward in the paper is a comprehensive and applicable.A field case verified that the optimized design of fracturing plan determined using the expert system has a higher post-fracturing rate than that using ordinary fracturing design method.
