A油田在纵向上储层多，且各油层物性相差悬殊、流体性质各异、储量分散。油田在笼统注水或多层合采开发过程中，势必会受储层非均质影响，逐渐暴露出注入水单层突进、含水上升快、储量动用程度不均、各层采出程度不等、油藏采收率低等问题。如何提高此类纵向非均质油藏的采收率是当前所面临的重要问题。以油藏数值模拟技术为手段，根据A油田均质模型进行了多层合采条件下层间干扰的单因素以及复合因素的敏感性分析，并针对油田实际非均质模型进行了不同开发方式下储层动用特征、开发效果评价以及开发指标对比，推荐了该油田切实可行的开发技术方案、提出了指导类似油田开发的技术策略和措施。

There are several vertical reservoirs in A Oilfield,and the greatly different reservoir physical properties,different fluid properties,and the disperse reserves. Because of these factors,in the cause of commingling water injection or commingling oil production,some problems caused by reservoir heterogeneity will gradually arise,which include serious injected water breaking through in single layer,quick increase of water cut,different reserves producing,unequal oil recovery and lower reservoir oil recovery. So how to improve the recovery is very important in the vertically heterogeneous reservoir. This paper uses numerical simulation technology to conduct the single and composite factor sensitivity analysis under the condition of commingling production by A oil field homogeneous model,and reservoir production characteristics,development evaluation and development index are compared in different development method by the actually heterogeneous model. In the end,we recommend technology development program practical in Oilfield,and put forward Oilfield development technology strategy and measures.
