摘　　要：郭局子洼陷沙二段储层以滩坝砂体和小型扇体为主,分布规律性不强,勘探程度较低.我们采用弧长属性和相干分析技术较为准确地识别并描述了储层分布范围和低序级断层,有效地指导了该区该类储层的勘探.The Es2 member reservoir of the Guojuzi sag is mainly bank and bar sands and small-scale fans, which are in irregular distribution. The reservoir is currently in a low-degree exploration stage in the area. We use the arc length attribute and coherence technology to predict and describe sand distribution and small faults. The research has effectively instructed the exploration of this kind of reservoirs in the region.
