依据模糊决策方法,对压裂设计方案进行了优选。该方法改变了以往压裂设计中只考虑单一优化目标函数的作法,综合考虑了不同压裂设计方案中的多个性能指标,因而可以认为更趋合理化。与以往压裂优化设计方案相比,结果与实际更相符。
According to the fuzzy decision principles, this paper gives an optimum selection for well fracturing design programs. The new method changed the way in which only a single optimum target function was considered in previous design. It supplies a comprehensive consideration for many target performances in different design programs. Therefore, it is believed that it’s more reasonable. The results obtained from the new design method are more practical than those obtained from the previous optimization design program.
