摘要
目标区块属于典型的碳酸盐岩油藏,天然水体能量较强,在开发过程中油井见水后含水上升较快,特高含水阶段油井增多,影响油田开发效果。为有效控制油井含水率快速上升,稳定产油量,通过优化油井生产制度,控制油井生产压差,抑制了底水水锥的高度。基于底水油藏临界产量公式,计算单井水锥高度,控水后水锥高度降低,含水率下降。运用动态稳油控水方法,在受底水影响的特高含水井上取得明显控水增油效果,并在同类型高含水单井中得到推广应用。
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.
