摘要： 为研究大庆油田过渡带提高采收率方法, 通过对大庆油田 A区块过渡带与纯油区近5年开发指标对 比, 采用岩心驱油实验, 数值模拟等方法, 考察了过渡带地区聚合物驱和三元复合驱的适应性。研究结果表明, 过渡 带地区与纯油区相比整体水驱开发效果较差, 三、 四条带水驱效果明显低于一、 二条带的。一、 二条带聚合物岩心驱 油实验可提高采收率1 2%以上, 三元复合驱可提高采收率2 0%以上, 一、 二条带适合聚合物驱和三元复合驱, 而三、 四条带适合三元复合驱。一、 二条带适合采用五点法井网开采, 而三、 四条带适合采用九点法井网开采。一条带聚 合物驱和三元复合驱最优注采井距为1 0 6m, 三条带注采井距为7 5m。

Abstract: Methods of improving oil recovery of transition zone in Daqing oil field was studied. The adaptability of polymer flooding and ASP flooding transition zone was researched by water flooding development effect, core displacement experiment and numerical simulation method, etc. The results show that transition zone water flooding development effect is poorer than single oil area. Three or four stripes of water flooding effect are significantly lower than one or two stripes. One or two stripes polymer flooding can increase oil recovery by more than 12%, and ASP flooding can increase oil recovery by more than 20%. The polymer flooding and ASP flooding are suitable for one or two stripes. The ASP flooding is suitable for three or four stripes transitional zone. The fivepoint well pattern is suitable for one or two stripes, and ninepoint well pattern is suitable for three or four stripes. The optimum injectionproduction well spacing of one stripes is 106 meters, and three stripes injectionproduction well spacing is 75 meters.
