摘　　要：影响压裂酸化选井因素多,而且各因素具有不同的影响程度,它们之间关系复杂。传统的选井方法依据经验,具有一定的主观性,盲目性。运用灰色关联分析很好地解决了这一高度非线性的问题。确定权重时采用系统工程层次分析原理,考虑了影响选井因素的复杂性和不均衡性,确定的各因素的权重更加符合实际情况。该方法计算结果正确,符合现场施工实际;计算简单、方便。To obtain good fracturing and acidzing treatment,it is important to select appropriate working wells. There are many factors that influenced in choosing the right working wells. The relations between them is very complicated. The traditional!methods of choosing the wells are based on the experience,which possess definiue subjectivity. This nonlinear problem can be solved by grey correlation analysis method. The weight of different factors is calculated by level analysis principle of systematic engineering, which takes the factors' complexity into consideration. The result of this method is accurate and reliable, and it is according with the practical effects. This method is simple and convenient. So it has a certain practical value.
