摘要
为了进一步扩大聚合物驱在不同类型油层上的应用，参考“两三结合”先导性试验区的资料，针对萨中开发区高台子油层进行了聚合物驱数值模拟合理注入参数的优选，并对聚合物驱提高采收率指标进行了预测。优选聚合物注入参数为：注入聚合物分子量为800×10^4，浓度为800mg／L，年注入速度为0．10PV，聚合物驱油时间为7a，聚合物用量为560mg／L·PV，总注入孔隙体积为0．70PV。萨中开发区高台子油层聚合物驱提高采收率为4．29％。
In order to further apply the polymer flooding to diflerent types of oil reservoirs, the reasonable injection parameters were optimized for the numerical simulation of the polymer flooding in Gaotaizi oil reservoir of Sazhong development area based on the data from the pilot area, and the improved recovery factor of the polymer flooding was predicted. The optimized polymer injection parameters were as follows： the molecular weight of the injected polymer was 800 ×10^4 with the concentration of 800 mg/L, the annual injection rate of 0. 10 PV, the displacement period for polymer flooding of 7a, the polymer amount used of 560 mg/L · PV and the total injection pore volume of 0.70PV. The improved recovery factor for the polymer flooding in Gaotaizi oil reservoir of Sazhong development area was 4.29 %.
