摘　　要：针对油层堵塞、油藏非均质性严重,导致水驱采收率较低这一实际问题,提出了井下低频脉动注水技术。分析了井下低频脉动注水技术提高水驱采收率机理,介绍了几种国外具有代表性的井下低频脉动注水工具,阐述了胜利油田研制开发的JMZ5/25型井下低频脉动注水工具。对提高水驱采收率具有重要的现实意义。To direct toward the lower recovery rate of waterflooding because of formation blockage and oil pool lack of homogeneity, downhole low-frequency pulsing injection technology was put forward. The mechanism of enhancement of recovery rate of downhole low-frequency pulsing injection was analyzed, the operating mechanism and characteristics of several kinds of representa- tive downhole low-frequency pulsing injection tool were introduced, and JMZS/25 downhole lowfrequency pulsing tool of Shengli oilfield is also presented in this paper, which are of great benefice in improving recovery rate of oil field.
