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。

Abstract

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

J urassic 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 oilfield1
