摘要
应用PI(注水井井口压力指数 )决策技术 ,实施区块整体调剖决策 ,可提高复杂断块油田高含水期最终采收率 ,减缓油藏产量递减 ,搞好控水稳油。该技术在濮 53块应用后 ,油藏各项开发指标均得到改善。PI决策技术操作简单 ,实用性强 ,适用于高含水期油田调剖堵水的需要 ,但需区块整体调剖与三次采油相结合 ,才能得到最佳的控水稳油效果。
Applying PI(the surface pressure index of injection well) decision technology and doing well the profile control decision in all blocks, which upgrades the final oil recovery in high water-bearing period of complicated blocks oilfield and reduces the production declines for improving the control water and static data of reservoir.After this technique applied in 53 block,each development targets has been improved.PI decision technique adapts to the needs of the profile control water block off in high water-bearing period for its simple operation and high feasibility.It can obtain the optimal effects of water control by the combination of profile control in full block and tertiary oil recovery.
