摘　　要：通过露头剖面、岩心、样品分析及测井等资料对富县Y64区延长组长6段储集砂体分析表明,区内长6段低孔低渗砂体的非均质性强,不同小层存在差异。垂向上,长63至长61的非均值性逐渐增强;平面上各小层非均质性随着砂体变厚总体上有增大的趋势。Chang 6 reservoirs sandstone of Yanchang formation in Fuxian Y64 area was studied by the information of outcrop,core,sample analysis and logging,and so on.The results show that the low porosity and low permeability sand body in Chang 6 reservoir is characterized by strong heterogeneity,and its heterogeneity is different among different subzones.Heterogeneity of Chang 63 to Chang 61 sandstone generally increases in vertical direction;In horizontal direction,homogeneity of the layer generally increases with increasing of sand body thickness.

关 键 词：储层非均质性 层间非均质性 层内非均质性 平面非均质性
