摘　　要：精控压裂是高含水、特高含水油田薄差油层改造的重要措施，合理准确的选井选层标准是精控压裂取得较好措施效果的前提．基于层次分析方法结合模糊数学理论，形成了一种新的精控压裂井层优选评价方法，利用层次分析方法明确主要影响因素，结合模糊综合评价定量评价措施效果并形成精控压裂选井选层标准．应用结果验证了方法的准确性及适用性，对精控压裂井层优选具有一定的指导意义和应用价值．Fine controlled fracturing is an ei^icient measure of developing thin and poor reservoir at high watercut stage, and wells and layers selection plays an important role. A new optimization method of fine controlled fracturing wells and layers is established based on hierarchy theory and fuzzy mathematics. The main influencing factors are determined by analytical hierarchy process of fractured layers parameters, quantitative evaluation of fracturing could be obtained by fuzzy comprehensive evaluation, and then wells and layers selection stare dard is established. Application in thin and poor reservoirs of Daqing oilfield shows that the method is simple, convenient and accurate, it may provide certain guidance and application value to the selection of wells and layers in fine controlled fracturing.
