摘　　要：在压裂施工前必须进行合理的压裂设计,有时需要从多个压裂设计方案中进行优选。而目前,压裂方案优选时仍然采用传统的单一目标函数的作法,即使有时也综合权衡其他因素的影响,也往往是凭经验,缺乏科学的运作程序。综合考虑影响压裂设计方案优选的各因素并运用系统工程的层次分析法获得各因素的权重,然后运用模糊数学原理建立压裂方案优选的综合决策模型。该方法综合考虑了压裂方案优选中的多个因素指标及其不同的影响程度,因而选择结果更加合理可靠。计算实例表明该模型计算结果准确,具有一定的推广价值。It is necessary to optimize fracturing design before fracturing treatment.Sometimes,we must select the best fracturing design from several fracturing projects.At present,the selection methods,which take some factors into consideration occasionally,are based on singleness objective function.They depend on experience and lack of scientific basis.In the paper,the weights of different factors are calculated by level analysis principle of systematic engineering.The comprehensive decision-making model is established by using fuzzy mathematics theory,which takes the different factors and their weights into consideration.So the results are more reasonable and reliable.The case study shows that the result of the model is accurate and it has a good generalization value.
