摘　　要：以过渡带隔相注水工艺、实行微破裂压力注水及调剖、调驱等多种工艺结合进行合理注水 ,可以达到对非均质油藏系统开发 ,使低渗层水驱动用程度及驱油效率得以提高 ,对应油井地层压力上升、产能增加 ;这一水驱油工艺在桥口油田应用 ,实现了油田连续 6年控水稳油 ,证实可以有效减缓油田自然递减 ,保持油田持续稳产高产 。Using water flooding technology in intermediate zone,minute-fracture pressure water injection and profile control etc.technique carry out rational water flooding,can reach the goal of systematical development heterogeneous reservoir and make degree of water-drive and oil displacement efficiency of low ooze layer improve,formation pressure and productivity of correspondnece oil well increase.Through field application of the water injection oil displacement technique in Qiaokou Oilfield,the results show that the technology can slow down effectively natural lapse of oilfield and keep stable production and high production of oilfield.
