摘　　要：萨尔图油田北二区东部密井网区是为提高最终采收率和提高油田产量而设的生产试验区。利用密井网区的开发井测井资料，研究了油田开发区块的储层特征和剩余油特征，将区块储层分成河道砂型、河道边部型和席状砂型三种类型。河道砂型的剩余油主要为厚层内未水淹型、滞留区和二线受效型；席状砂型的剩余油主要为油层开采不平衡型；河道及边部型的剩余油主要为注采不完善和井网控制不住型。利用容积法计算了各油层的剩余地质储量和原始地质储量，从而定量了分析剩余油分布。The experimental area in the east of the second region in the north of Saertu Oil Field is the pilot area for drilling infilling well to improve the ultimate recovery factor and increase production rate of Daqing Oil Field. This paper deals with the reservoir feature and residual oil distrubition based on the loggingdata of the production well. The region block reservoirs can be divided into three types. Then, it analyzes three different reservoir types of residual oil, and calculates the grid remaining geological reserves and total remaining geological reserves of every oil bed group in the study area by using the methods of volumetric.
