摘　　要：针对薄差储层砂体薄、砂体连通性差、低孔低渗及层间非均质性强致使动用效果差,采出程度低的问题,以大庆油田萨中开发区高台子薄差储层为例,利用数值模拟方法研究化学驱动用规律,分析化学驱参数及聚驱作用效果,通过矿场实践进行验证。结果表明,储层整体采收率提高7.84%,薄差储层采收率提高8.85%,实现储层的均衡动用。This paper is a response to the poor production effect and low recovery degree caused by the thin and poor reservoir sand body,poor sand body connectivity,low porosity and low permeability,and strong interlayer heterogeneity.By taking Gaotaizi thin and poor reservoir in Sazhong development area of Daqing Oilfield as an example,the study involves studying the chemical driving law by numerical simulation method,determining the chemical drive parameters and polymer flooding effect;and conducting the field practice.The results show that the overall recovery rate of the reservoir increases by 7.84%,and the recovery rate of the thin and poor reservoir increases by 8.85%,realizing the balanced utilization of the reservoir.
