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。

Abstract

It is necessary to optim ize fractur ing design be fore
fracturing treatm ent. Som etim es, we m ust se lec t the best
fracturing design from severa l fractu ring pro jec ts. A t present,
the se lec tion m ethods, wh ich take som e factors into
consideration occas iona lly, are based on sing leness objectiv e
function. They depend on expe rience and lack of sc ientific
basis. In the pape r, the w e ights o f different factors are
ca lcu la ted by leve l ana ly sis pr inciple o f system atic
eng inee ring. The comprehensive dec ision - m ak ing m ode l is
established by using fuzzy m a them atics theory, w hich takes
the different fac tors and the ir we ights into consideration. So
the resu lts a re m ore reasonab le and re liab le. The case study
show s that the resu lt of the m ode l is accurate and it has a
good g eneralization va lue.
