摘要
水驱油田进入中高含水期,注采系统不适应性的矛盾越来越严重,通过对注水井和采油井采取精细地质方案编制,加强测试管理,扩大周期注水应用规模,加大深、浅调技术应用力度等一系列措施,适时调整区块的注采系统,能够减缓产量递减并控制含水上升速度,提高区块采收率,减少无效注水和无效产出,达到节能节水的目的。全年共对矛盾突出的236口注水井的264个层段实施了控水调整,调整后日实注水减少3 410 m3。
At the medium-high water cut stage of water flooding oilfield, the production decline can be slowed, the velocity of water cut can be controlled, the enhanced oil recovery can be improved, the ineffective injection and invalid output can be reduced, and the energy-saving & water-saving can be achieved by enhancing the logging & testing management and expanding the scale of water injecting. The water controlling adjustment has been done in 236 wells and 264 layers. After adjusting, the amount of 3 410 m3 injecting water has been reduced per day.
