探讨准噶尔盆地东部阜康凹陷的阜东斜坡区头屯河组储集层非均质性，为储集层开发以及采油率的提高提供理论帮助。从宏观与微观非均质性入手，通过粒度、渗透率、夹层、砂体的几何形态的变化研究，对研究区头屯河组进行非均质性剖析。结果表明，头屯河组整体非均质性较强，尤其是头屯河组第二段。沉积背景的差异对于储集岩的岩石成分和沉积特征产生重要影响，A/S比值变化加剧储集层宏观非均质性程度；弱成岩作用以及地层超压的不均匀分布改变储集层内部孔隙结构以及孔隙类型，对储集层微观非均质性有重要的影响。头屯河组储集层非均质性强是上述多种原因共同作用的结果。

This paper discusses the degree of reservoir heterogeneity in east of Fukang sag,eastern Junggar Basin to offer theoretical helps to the development of the reservoir.The research of the reservoir heterogeneity on the Middle Jurassic Toutunhe Formation includes the analyses of macroscopic heterogeneity and microscopic heterogeneity based on the size,permeability,dissection and geometry of the reservoir sandbodies.The result shows that the whole Toutunhe Formation has strong heterogeneity,especially the second member.The change of sedimentary background has a great influence on rock elements and sedimentary characters of the reservoirs,and the variety of A/S value intensifies the degree of the reservoir macroscopic heterogeneity.The weak diagenesis and the differential distribution of the strata overpressure change the structures and types of the pores.This has great affection on the microscopic heterogeneity.All the above factors make the reservoirs of Toutunhe Formation in study area have strong heterogeneity.
