摘　　要：物性较好且孔隙结构分选和连通性较好的储层,其驱油效率较高;在注水开发初期,提高注入压力和增加注入量,对驱油效率的影响较明显,当注入量超过3Pv之后,二者的增加对驱油效率的影响将明显减弱。Based on the water flooding experiment of the authentic sandstone micro-model,influencing factors of water displacing oil efficiency of Xishanyao formation in Niuquanhu Oilfield is studied.The results show that,reservoirs with better physical properties,well-sorted and well-connected Pore Structure its oil displacement efficiency is better;early in water flood development,when improve injection pressure and increase quantity,the effect on oil displacement efficiency is obvious;but,when injected is over 3Pv,the effect on oil displacement efficiency is weakened obviously although injection pressure and increase quantity are both increased.
