| 摘 要： | 根据对大量取心井样品的压汞曲线、薄片、扫描电镜等资料，分析了临盘油田储层岩矿特征及微观非均质性，将本研究区储层孔隙结构划分为五种类型。通过对本区河流一三角洲沉积体系内各微相砂体的平面及空间展布、砂体的几何形态和储层岩性、物性及含油性特征等研究，揭示了临盘油田古近系沙河街组储层的宏观非均质特征。总体采看，储层在平面上及垂向上、层间及层内的非均质性均较强。其非均质程度受沉积微相和成岩作用控制，注水开发也改变了储层参数的分布格局。研究结果有利于合理划分开发层系，选择注采系统，为改善临盘油田的开发效果提供可靠的地质依据。

| Abstract: | According to the intrusive mercury curve, thin section, scanning electric scope and other datum of the core samples, this paper analyses micro reservoir including mineral and lithological feature, micro-heterogeneity of Linpan oilfield. Based on the research of the distribution of sedimentary sand bodies, petrological and physical features of the reservoir characteristics, macroscopic heterogeneity of the reservoir in Shahejie formation of Peleo- gene, Linpan oilfield, Huimin depression is analyzed. The results show that the heterogeneity in the studied area is serious and it is controlled by sedimentary environment, diagenesis and tectonic movement. The wateff/ood de- velopment influences the heterogeneity of the reservoir to some extent. So more attention should be paid to the re- search of heterogeneity to increase production and improve the development efficiency of the oilfield. |
