摘　　要：研究区地处陕北斜坡中部,延9油层是其重要的含油层系之一,属曲流河相。本文充分运用岩心、录井和测井等资料,对其储层非均质性进行研究。研究区延9油层组层内非均质性较强,层间非均质性和平面非均质性较弱,沉积微相是影响储层非均质性的主要原因。Caoyaoxian is located in central area of north Shaanxi slope in Ordos basin.Major reservoir is Jurassic Yan'an 9 formation,and Caoyaoxian Yan 9 formation is mainly considered to develop river facies.In the article,reservoir heterogeneity was studied by observation of a large number of cores and well log analysis.The results show that the layer heterogeneity of the area is relatively strong,the interlayer heterogeneity and plane heterogeneity are weak;main reason of reservoir heterogeneity is sedimentary microfacies.

关 键 词：曹崾岘地区 延9油层组 储层非均质性
