摘　　要：渤海某油田B区的开发已进入中高含水阶段,面临油井供液不足、含水上升快、产量递减迅速等问题。针对上述问题,文章应用油藏工程理论方法,利用渤海相似油田类比、水驱储量动用程度、含水上升率、递减率及存水率等评价指标,对该区块的注水开发效果进行评价研究,认为B区具有采油速度高、含水上升快、递减率大的特点。The development of Block B in the Bohai Sea has entered a stage of medium to high water cut,facing problems such as insufficient oil well supply,rapid increase in water cut,and rapid decline in production.In response to the above issues,this article applies reservoir engineering theory and methods,using evaluation indicators such as analogy of similar oil fields in Bohai Sea,degree of water drive reserve utilization,water cut increase rate,decline rate,and water storage rate,to evaluate and study the water injection development effect of this block.It is believed that Block B has the characteristics of high oil recovery rate,fast water cut increase,and large decline rate.
