摘　　要：腰英台特低渗裂缝型油藏储层非均质性严重,注水开发特征表现为水驱储量控制程度低,注水压力高,波及体积小,沿高渗透带突进明显,水淹程度高,而在低渗透带剩余油丰富。通过水井重复射孔、油井转注、水平井分段压裂、水井调剖、周期注水等方式有效地改善了其注水开发效果。The ultra-low permeability fractured reservoir in Yaoyingtai has a serious anisotropy and the water injection development has the characteristics of low degree of waterflooding reserves,high water injection pressure,small swept volume,obviously marching forward along high permeability zone,high waterflooding degree and abundant remaining oil in low permeability zone.Through different manners such as repeated perforation in water well,converted oil wells,staged fracturing of horizontal well,profile modification of water well and cyclic water injection,the water injection development effect has been greatly improved.
