摘　　要：经过40多年开发,大庆萨尔图中部油田已进入高含水后期阶段,复杂的地下形式要求了解更加精细的储层特征。在主力油层葡萄花油层I组沉积相带图全面绘制完成的情况下,通过应用VFP,AutoCAD计算机技术将精细地质研究成果之一的小层数据库进一步开发利用,得到主力油层单元间夹层图,从而首次实现了对萨尔图中部油田主力油层单元间沉积特征的整体描述,认识了平原相、三角洲内前缘相单元间夹层不同的特征,并指出了单元间夹层的发育、分布受上覆沉积单元河流相空间发育位置控制的规律,为油田高含水期开发、综合调整多提供了一种新的储层图幅资料。Over 40 years＇ development, it has entered the later stage of high watercut in the central Saertu Oilfield. Thus fine reservoir description is required to study the complicated geological conditions. Based on mapping the sedimentary facies belts of No. 1 Sandstone Group of the chief Putaohua Oilfield, this paper got the detailed map of the interunited interlayers in the chief zone using the computerized layer database resulted from the fine geological research, which led to carrying out the integrated description of sedimentary characteristics of interunited interlayers in the central Saertu Oilfield. Meanwhile, it indicated that the development and distribution of interunit interlayers were controlled by the development positions of overlying sedimentary units of fluvial facies which provided another new reservoir maps for further developing and integrated adjusting at the later stage of high watercut.
