摘　　要：本文从孔隙结构、物性、砂体展布等方面详细论证了文 2 5东块沙二下油藏宏观和微观非均质特征 ,建立了不同沉积微相的非均质模式 ,并结合油田开发特征 ,分析了各种非均质模式对油田开发生产的影响 ,指出平面上砂体发育的不稳定性及物性的方向性是影响注水面积波及效率的主要因素 ,层内重力作用是影响单砂层层内垂向上注入剂波及体积的重要因素。层内非均质性是造成 、 类层动用差的主要原因。This article demonstrates macro and microheterogeneity of reservoir in the east of Wen 25 Block according to its pore structure, physical property and sand body distribution, builds heterogeneous model of different sedimentary microfacies, and analyzes the influence of oilfield production ty the heterogeneity. It is pointed out that instability of the sand bldy and directionality of the physical property are the main factors of water injection efficeency. Gravity is the main factor of injection swept volume in the single zone in vertical dirction and heterogeneity is the main reason of low production in zone Ⅱ and Ⅲ.\;
