The target oilfield is a typical carbonate reservoir with strong natural water energy.During the development process,the water cut of oil wells rises rapidly after water breakthrough,and corre-spondingly ultra-high water cut wells increase,which affects the development effect of this oilfield.In order to effectively control the rapid rise of water cut and stabilize oil production,this paper puts forward a method to optimize oil wells'production system,control the production pressure draw-down and the height of bottom water coning.Based on the critical production formula of bottom water reservoir,the height of water cone was calculated,after optimization,the height of water cone de-creased and so did the water cut.The dynamic oil stabilization and water control method has been applied to the ultra-high water cut wells with bottom water,and has been popularized and applied to other wells of the same type.
