摘　　要：滨南油田滨2断块处于中采出程度、低采油速度和中高含水开发阶段,为了优化滨2块整体注采结构,提高区块最终采收率,在精细三维地质模型基础上,开展了历史拟合及剩余油分布规律研究和注采参数实时优化。根据基于Eclipse数值模拟软件的生产优化控制模型,利用优化算法和数值模拟完成了目标区块油水井动态调控参数的5年优化方案,对比基础方案,提高采出程度3.01%,效果良好。The Bin2 fault-block in Binnan Oilfield is in the development stage of medium recovery degree,low oil production rate,and medium-high watercut.To optimize the overall injection-production structure of the Bin 2 block and increase the final recovery rate of the block,based on the fine 3D geological model,it has been carried out studies on history matching and remaining oil distribution law and real-time optimization of injection-production parameters.According to the production optimization control model based on Eclipse numerical simulation software,a five-year optimization plan for the dynamic adjustment parameters of oil and water wells in the target block was completed using optimization algorithms and numerical simulations.Compared with the basic plan,the production rate was increased by 3.01%,and the effect was good.
