| 摘 要： | 高浓度聚合物驱作为常规聚合物驱后进一步提高采收率的方法，其提高采收率的幅度或取得的经济价值与井网、井距等均有密切的关系。利用数值模拟方法，通过对大庆油田中区西部葡一组进行精细数值模拟研究，对中区西部高浓度聚合物在不同井网、井距、不同注入速度以及不同注入浓度条件下的驱油效果进行评价及优选。结果表明:采用九点法、小井距、高浓度、高注入速度的开发方案，能够达到最优的开发效果。为现场开展高浓度聚合物驱提供开发依据。

| Abstract: | High concentration polymer drive is a further enhanced oil recovery method after conventional polymer flooding.Its economic value depends on well pattern and well spacing.In this article, we evaluate oil displacement efficiency of high concentration polymer at different well pattern, well spacing, injection rate and concentration by fine numerical simulation in Pu-1 oil group of Daqing oilfield.Research shows that the development plan of nine point well pattern, dense well spacing, high concentration and high injection rate can achieve best development effect.This provides a basis for carrying out field high concentration polymer flooding. |

| Keywords: | high concentration polymer flooding numerical simulation well pattern injection rate enhanced oil recovery |
