摘　　要：针对注入水的水质影响特低渗透油藏的开发效果 ,结合物理模拟实验 ,用油藏数值模拟的方法 ,建立不同注入水水质条件下 ,特低渗透油藏流体流动的数学模型。分析了注入水的水质对特低渗透油藏开发效果的影响 :在一定的水质处理条件下 ,可以通过减小注采井距或压裂措施 ,来提高特低渗透油藏的动用程度。In view of the problem of development result affected by injected water quality, combining with physical simulation, a mathematical model of fluid flow in extra low permeable reservoirs for varied injected water qualities has been established through reservoir numerical simulation. The effect of injected water quality on the development efficiency of low permeable reservoir is analyzed. Under limited water treatment conditions, producing degree of extra low permeable reservoirs can be improved through reducing producer injector spacing or fracturing. This study provides theoretical instruction for water flooding in extra low permeable reservoirs.
