摘　　要：根据大庆油田采油二厂提供的动、静态数据,用数值模拟方法,分析了其南八区西块二类油层的剩余油分布.针对其剩余油的挖潜设计了注水时机、注水强度、注水时机和注水强度优化三套30个补孔方案,优化结果是:注水强度9最好,注水时机含水93%最好,注水强度9和注水时机93%结合优化效果最好.The distribution of remaining oil in the west of South-eight Block has been analyzed by using the method of numerical simulation according to dynamic and static data provided by the 2nd Oil Production Factory in Daqing oilfield. Three sets and 30 schemes of perforation adding about the timing of water injection, injection intensity, and orthogonal scheme have been designed aiming the tapping of remaining oil. The optimization results are： the best water injection intensity is 9, the best timing of water injection is 93% of water cut, and best orthogonal scheme is that when the water injection intensity is 9 and timing of water injection is 93%.
