摘    要:桩西油田桩45—1块储层非均质性严重,长期强注强采,油层高渗透带形成大孔道,造成注水开发效果差、产量递减大。通过数值模拟研究,对周期注水的不同注水方式、周期、注水量波动幅度等参数进行优化,在该块进行周期注水实践,提高了注水波及体积,抑制了单元含水的上升,提高了单元采收率,取得了较好的注水开发效果。

关 键 词:桩西油田桩45—l块 周期注水 数值模拟 方案优化

Abstract:Because of serious reservoir heterogeneity, long-time intensified injection and production, the large channels with high permeability in formations had emerged, thus leading to the poor effect of water injection and the decreasing oil production largely in Zhuang 45-1 block of Zhuangxi oilfield. The parameters of water injection mode, cycle, fluctuation magnitude of water injection rate and so on of cyclic waterflooding are optimized by numerical simulation. Cyclic waterflooding is implemented in this block achieving good results of enhancing sweep volume of water injection, inhibiting unit water cut from increase and enhancing the unit oil recovery.
Keywords:cyclic waterflooding   numerical simulation   project optimization   effect   recognition
