分层注水技术水平直接影响着注水开发油田的整体开发效果。针对华北油田分注技术状况，剖析了目前分注工艺技术存在主要问题；结合华北油田储层特点，优选出桥式偏心分注、桥式同心分注、免投捞测调一体化分注等3 种分注工艺，引进了高效测调工艺，开展了系列分注配套工具研究。详细介绍了三类分注工艺的特点和在华北油田的应用情况，指出了分注技术的发展趋势。

The level of zonal water injection technology directly affects the development efficiency of oilfields developed by water injection. In view of the status quo of zonal water injection technologies in Huabei Oilfield, the main problems were analyzed; by combining the reservoir characteristics of Huabei Oilfield, three zonal water injection technologies were selected: bridge-type eccentric zonal injection, bridge-type concentric zonal injection and integrated zonal injection free from dropping, fishing, testing and adjusting; high-efficiency test and profile control technology was introduced; the research on a series of accessory tools for zonal injection was performed. This paper gives a detailed introduction to the characteristics of these three zonal water injection technologies and application in Huabei Oilfield, and points out the development trend of zonal injection technology.
