摘　　要：我国东部油田的粉砂岩储层是主要的产能层之一，储层具有颗粒细、孔径较小、孔隙度和产液能力相对较低的特点，储层岩石的成份成熟度和结构成熟度普遍较高。高分辨率阵列感应测井在聚焦方式、工作频率、纵向分辨率、径向探测深度和测量信息方面都明显优于常规感应测井，通过实际应用效果分析，高分辨率阵列感应测井响应特征对识别粉砂岩储层中的流体性质，效果非常明显。Siltstone reservoir,which has fine grains,small aperture,low porosity and hquid-producing capacity,high maturity of rock component and structure,is one of the primary productive zone in the east oilfield of our country.High resolution array induction logging is more advanced than conventional one in focusing mode,working frequency,axial resolution,radial investigation depth and metrical information.Through practical application effect analysis,high resolution array induction logging has gained good result in identifying the fluid properties in a siltstone reservoir.
