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 Mizuhoku-ku, east of Kita-ku, Sa’atu oilfield, is a production test area designed to increase the ultimate recovery rate and increase oilfield production. Based on the well logging data of the Weijing Network, the reservoir characteristics and remaining oil characteristics of the oilfield development block are studied. The block reservoirs are divided into three types: channel sand, channel edge and sand sheet. Remaining oil in the channel sand is mainly un-flooded, stagnant and second-line in the thick layer. The remaining oil in the masonry sand is mainly unbalanced in the production of the oil layer. The remaining oil in the channel and the marginal area is mainly injected and reclaimed Perfection and well network control type. The residual geologic reserves and the original geological reserves of each oil layer were calculated by the volumetric method to quantitatively analyze the remaining oil distribution.
