摘　　要：大庆油田进入中后期开采阶段后,在长期持续注水条件下,流体(油和水)的性质、动力学特征和储层物性发生了明显变化,导致储层内高渗透低效循环带的形成,严重影响油田的开发效果和注采系统井网布局方案的设计。通过该方法在萨南二、三区的具体应用,我们认为本文所述方法既考虑了含水、累积注水等开发动态因素,又考虑了孔隙度、渗透率等静态因素,因此具有一定科学性和综合性。并且该方法具有一定可操作性,符合率较高,具有很好的推广应用价值。After Daqing oil field enters into the mid to end exploitation phases, under the condition of persist water injection over a long period of time, the property, the dynamics characteristic of the fluid （ oil and water） and the reservoir property take place the obvious variety. It cause the formation of high perme- able, low efficient cycle band in the reservoir, seriously influencing the development result of the oil field and the pattern arrangement design of injection--production system. Through the concrete applications in 2, 3 blocks of Sanan, It is considered scientific and synthesize because not only the dynamic factors, such as water--cut and the cumulative water injected, but also static factors are all thought over. And it has the certain maneuverability, the higher matching rate and the good application value.
