摘　　要：充分应用吴起油田旗56-122区的地质资料和动态数据,从平面和垂向两个方面对研究区的剩余油分布情况进行了分析。结果表明,长912小层剩余油饱和度高,呈连片状分布,长911小层次之,长913小层剩余油分布最少,呈分散状分布;从垂向来看,长912小层剩余储量最多,潜力大。并且设计了两套方案,其中加密方案的产油量更高且含水率低。本文的研究可以指导今后该区块的高效生产。The geological data and dynamic data of Area 56-122 of Wuqi Oilfield were fully applied, and the remaining oil distribution in the study area was analyzed from both plane and vertical aspects. The results show that the residual oil of the Chang 912 small layer has high saturation and is con-tinuously distributed, the Chang 911 small layer is long, and the remaining oil of the Chang 913 small layer is the least distributed and has a dispersed distribution;from the vertical point of view, the remaining reserves of the Chang 912 small layer are the most and the potential is large. And two schemes were designed, in which the encryption scheme produced higher oil and had a low moisture content. The research in this paper can guide the efficient production of this block in the future.
