摘　　要：针对目前注水井由于注入水水质污染造成油层结垢、机械杂质堵塞,有效注水周期短,影响油田注水开发效果等问题,研制了高频强磁射流振荡注水技术,系统介绍了技术原理、选井条件、设计原则及施工工艺。该技术通过磁化水处理防垢、射流振荡解堵等作用,达到改善注入水水质、提高地层吸水能力的目的,在东辛油田现场试验8口井,注水效果显著,经济效益和社会效益较好。According to reservoir scale, impurity plugging and shortly effective injection period caused by water pollution from water injection wells, which influences the effects of field injection and development, the high frequency and strong-magnetic jetting oscillation injection technology has been developed. Through descaling with magnetized water and unplugging by jetting oscillation, the improvement of injecting water quality and formation water injectivity have been achieved. The paper presents the theory, well conditions, design principle and operation processes. The technology was used in 8 wells in Dongxin oilfield and the injection effect was re- markable.
