摘　　要：压裂是油气田开发的重要增产措施,选择合适的井层进行压裂至关重要.压裂选井时需要综合考虑多种不同的因素,而且各因素在不同程度上影响压裂效果,因素间又相互影响关联.为优选适宜压裂的井,运用灰色关联法综合考虑11种因素,用效果测度函数进行无量纲化,层次分析法求取因素权重,最后以带权的灰色关联度指标优选压裂井.通过实例验证了方法的可靠性与适用性,且计算简单,可指导压裂选井工作,并具有可推广性.Hydraulic fracturing is an important stimulation method in oil and gas field development, so it is very important to select appropriate wells and layers. A variety of factors should be considered when selecting wells, and the factors influence the fracturing effect in different degree, and mutual influence between factors. To select appropriate wells and layers, 11 kinds of factors are considered by fuzzy grey correlation analysis method, and the data dimensionless through function transformation and the factor weights acquired by analytic hierarchy process. Finally, the weighted grey correlation index is used to optimize fracturing wells. Reliability and applicability of the method is verified by examples. This method has simple calculation, and can be sued to guide select wells, and has replication potential.
