摘　　要：影响压裂酸化选井的因素很多 ,而且因素本身具有一定的模糊性 ,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。借助现代数学手段———模糊数学和系统工程层次分析原理 ,考虑到影响选井选层因素的复杂性和不均衡性 ,将各因素按其在不同层次上对事物的影响程度分类 ,然后确定各因素最终的权重 ,形成一种压裂酸化选井选层的模糊综合评判方法。该方法计算结果正确 ,符合现场施工实际 ;计算简单、方便 ,具有一定的现场实用价值。To obtain good fracturing and acidizing treatment,it is important to select appropriate working wells. There are many factors that affect choosing the right working wells. The relation between them is very complicated and they possess definite fuzziness. The traditional methods of choosing the wells are based on experience,which possess definite subjectivity. With the aid of modern mathematical means: fuzzy mathematics and level analysis principle of systematic engineering, multi stage comprehensive evaluation measure is formed for choosing the right wells of fracturing and acidizing. The result of this method is accurate and reliable and is accord with the practical effects. This method is simple and convenient. So it has a certain practical value.
