摘要
为改善注水井吸水剖面 ,在注水井上应用多个封隔器和配水器 ,对不同的油层层段进行定量注水。该技术在沈 84-安 12块的应用表明 ,启动了新的吸水层 ,控制了高渗层吸水 ,提高了注水开发效果。对储层非均质性严重的注水砂岩油藏 ,多级分注工艺是改善注水井吸水剖面 ,提高油藏注水开发效果的重要手段之一。
In order to improve water injection profile, many packers and water allocators have been applied in water injection well to inject quantitatively into different reservoir intervals. Application of this method in block Shen84 An12 showed that new water entries had started, water entering into high permeable layers had been controlled, and water flooding efficiency had improved. For heterogeneous, water injection sandstone reservoirs, separate injection at multi stages is one of the important methods of improving water injection profile and water flooding efficiency.
