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。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。Conventional water-flooding leads 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.
