摘　　要：注水井实际注水量随系统压力波动或地层吸水能力的变化而改变,这是针型阀或井下固定水嘴无法避免的缺陷。本文介绍的定量注水技术采用了集减压节流为一体的"双级水嘴机构"这一基本理论模型。对理论模型到工程化应用转化过程中遇到的技术难点进行攻关,并结合目前油田注水井采用的水量控制方式进行产品开发和现场试验。定量注水技术研究的开展,将为油田注水井的管理提供有效的手段,大大降低作业费用。The actual water flooding amount in the water injection well is changed with the system pressure wave or variation of the water intake capacity. This is the inevitable weakness of the needle valve or downhole fix water nozzle. The quantification water injection technique introduced in the article adopted the basic theoretical model which is combined with the pressure release and throttling together 'double stage water nozzle structure', overcome the difficulties met from the theoretical model to actual application, conducted the products development and site experiments by the water amount control of the water injection well. This technology will improve the management of the water injection wells and operation cost.
