| 摘 要： | 三次采油技术的实践表明,聚合物驱技术既能扩大波及系数,又能提高驱油效率.为了从理论上清楚地认识黏弹性聚合物溶液的微观渗流特征,提出了用同位有限体积法对黏弹性聚合物溶液在简化油藏微观孔道模型中的流动特征进行数值模拟,建立了黏弹性聚合物溶液在突扩收缩流道内流动的数学模型,利用有限体积方法对数学模型进行离散求解,得到了流函数... |

| Abstract: | The practice of tertiary oil recovery shows that the polymer flooding can both enlarge the sweep efficiency and enhance the displacement efficiency.The numerical simulation of the flow characteristic of viscoelastic polymer solution flow in simplified reservoir channel model is carried by using non-staggered grid finite volume method.The mathematical model for the flow of viscoelastic polymer solution in abruptly expanding-suddenly contracting channel is established,and it is discretely solved by finite vol... |
