摘　　要：油水分布规律的准确掌握对柳坪坝区的后期开发、投资决策具有相当重要的作用。通过地质岩心观察、地质录井、岩样分析化验、测井解释、压裂试油等资料,对柳坪坝地区三叠系延长组T3y3进行地层的纵向划分对比及绘制沉积微相的平面展布特征。阐述了不同微相砂体所具有的物性、岩性、结构构造、非均质性等,而这些特性很大程度上决定着油水的分布、储存状态。It is crucial to study the relationship between oil and water for future exploitation,investment decision of Liu pingba area.With the data of drilling core searching,geologic control,formation sample analysis,log interpretation and fracture testing for oil,the article made vertical subdivision and compare of Yanchang formation T3y3 strata system in Liupingba area,then draw the map of sedimentary microfiche's flat feature.The map shows physical lithologic character,structural and tectonics,anisotropism of different sandbody,and these characters decide reserving mode and distribution of oil and water.
