摘　　要：从岩性、物性、孔隙结构、砂体展布等方面。详细讨论了孤东油田上第三系馆陶组不同沉积微相的非均质性，并结合油田开发特征，建立了辫状河心滩、曲流河边滩、河道充填及河道边缘４类主要储层的非均质模式，其中心滩、边滩砂体属中等非均质性储层，是油田开发最有利的油层；河道充填砂体属中偏强非均质性储层，是油田开发较有利的油层；河道边缘砂体则属较强的非均质性储层，属较差油层。The reservoir of the upper member of the Neogene Guantao Formation includes the sandbodies of 2 kinds of river facies sedimentary. Under the influence of types of the river and flow dynamic conditions, the heterogeneity of the sandbody is very good. From the lighology, reservoir characteristics, pore texture to the sandbody distribution, the heterogeneity models in the light of development characteristics of oilfield was studied. Among them, sand bars have middle-degree heterogeneity , and they are the best oil reservoirs. The heterogeneity of channel filling sand bodies is better,and they are good oil reservoirs. River embankment sandbodies have the best heterogeneity and they are worst oil reservoirs.
