摘　　要：利用EMI成像测井资料 ,识别储层岩石结构中的裂缝分布状况 ,采用Logview软件处理后 ,定量计算裂缝的宽度、密度、长度及视孔隙度等参数。在川西侏罗纪砂泥岩储层中良好的应用效果 ,说明了EMI成像测井技术能提供详细的储层信息 ,可直接用于计算裂缝和地应力参数 ,还可以通过多井评价进行地层构造特征和沉积环境研究 ,在油气田勘探开发中有着广泛应用前景。The EMI image logging is used in distinguishing distribution of fracture in rock structure.Some fracture parameters such as width,length,density and porosity are calculated by logview software.The excellent result in Jurassic sand and shale reservoirs of west sichuan shows that the image logging can provide detailed information of reservoirs,can directly calculate fracture and stress parameters,can still research layer structure feature and sediment environmental through well appraisement,have extensively application prospect in exploration and development of oilfield
