摘　　要：水驱采油指向地层中注入水,用水驱替出地质储层中的剩余油,从注水井注入水,地层压力会升高,由此会将地层原油驱替到附近的生产井内,注水技术自20世纪50年代以来,被广泛使用。通过对水驱油技术现状进行阐述,通过分层注水,精细化注水比,控制采油速度,保证地层压力等方面进行分析,为水驱油技术未来的发展提供了强有力的支持。Water drive oil production refers to injecting water into the formation to displace the remaining oil in the geological reservoir with water.Injecting water from the water injection well will increase the formation pressure,which will drive the formation crude oil to nearby production wells.Water injection technology has been widely used since the 1950s.The article elaborates on the current situation of water drive technology,analyzes the water drive technology through stratified water injection,refined water injection ratio,control of oil production rate,and formation pressure.It provides strong support for the future development of water drive technology.
