摘　　要：以濮城油田东区沙二下储层的沉积相、沉积微相和储层物性解释模型为基础 ,从微观、层内、层间、平面非均质四方面建立了储层分布与储层非均质性三维地质模型 ,并对开发生产调整措施的有效实施提出了建议。由于以上四方面的非均质性总体中等偏强 ,沉积微相的垂向分布、平面展布大小及砂体储油物性的平面变化对非均质性的控制极为明显 ,所以对于不同的沉积微相所对应剩余油量情况采用不同开采方式。对于层间非均质性大的层系 ,可采用有效封堵技术 ,或调整注采压力系统。对平面非均质性大的层系 。Based on sedimentary faces? micro-faces and interpreting model of porosity and permeability of the second segment of lower Shahejie group in eastern part of Pucheng Oil Field, this paper builds reservoir distribution and 3-D heterogeneous geological model from microstructure ?intra-layer?inter-layer and plain heterogeneity and gives some advice on the methods of development. These four heterogeneities are as a whole moderate on the high side and distribution of sedimentary micro-faces and reservoir porosity and permeability are obvious factors of controlling heterogeneity. Different mining methods should be used according to the different amount of retained oil in different sedimentary micro-faces. The enveloping and jamming technique or regulating pressure is efficient to high inter- heterogeneous sets. The continuity of sand is of the most important regard to high-heterogeneous sets in periodic flooding or reverse flooding.
