| 摘 要： | 超低渗油藏常规水驱开发的采收率较低，开发效果较差。本文通过室内实验和数值模拟研究，分析了注热水对原油性质、流固作用的影响以及注热水采油提高采收率的机理；数值模拟研究结果表明，对于特定的超低渗油藏注热水温度、注水速度、注水时长都存在最优值。研究结果对超低渗油藏热水驱开发具有指导意义。 |
| 关 键 词： | 超低渗透 热水驱 驱油机理 参数优选 |

| Abstract: | Conventional water-flooding lead a low recovery and poor development effect in ultra-low permeability reservoirs. Based on experiments in lab and numerical simulation study, the effects of injected hot water on the crude oil properties, fluid-solid interactions and the mechanism of enhanced oil recovery are analyzed. According to numerical simulation, there are optimal numbers of the temperature of hot water, injection speed, injection time in specific ultra-low permeability reservoirs. Results have significant guidance on ultra-low permeability reservoirs development. |
| Keywords: | ultra-low permeability hot-water flooding enhanced oil recovery parametric optimization |
