摘　　要：让纳若尔油田的A南和Б南油藏受开发方式、凝析气顶、储层物性及井网等影响,剩余油分布复杂。通过油藏数值模拟技术研究剩余油分布及受不同因素控制的剩余油平面和垂向分布模式,并提出具有针对性的挖潜对策,同时为减少A南难动用型剩余油(主要为凝析油)的损失,建议合理开发气顶。The remaining oil distribution of south A and south B reservoir in Zanarol Oilfield is complex due to the exploitation pattern, condensate gas cap, the physical property and well pattern. Based on reservoir numerical simulation, the paper describes remaining oil distribution, summarizes the plane and vertical distribution pattern of the remaining oil controlled by different factors, and brings up corresponding potential tapping. At the same time, in order to reduce the loss of remaining oil which barely can be extracted mainly including condensate oil, developing gas cap reasonably is suggested.
