Silicon-based nanoparticles (NPs) have attracted considerable interest for enhanced oil recovery (EOR) because of their environmentally friendly and cost-effective characteristics, because silicon compounds form a major part of sandstones and clays in nature. NPs can increase oil production through many mechanisms, which are related to the high surface area and aspect ratio. EOR methods generally affect the microscopic and macroscopic sweep efficiency, and NPs have a great impact on both phenomena. This paper reviews the effects of silicon-based NPs on the wettability alteration of porous media, interfacial tension between oil and nanosystems, the viscosity of production and injection fluids, asphaltene precipitation prevention, and pore channel plugging. Besides, it compares the oil recovery factor between nanosystems and water injection on glass micromodel and rock cores. It is worth mentioning that the effects of nanofluid/oil/rock properties including size and concentration of NPs, type, porosity, and permeability of rocks, density and viscosity of oil, salinity type and concentration of base fluid, and experimental conditions such as pressure, temperature, etc. have been comprehensively analyzed on each mechanism.

硅基纳米粒子对提高石油采收率的影响:综述

硅基纳米粒子 (NPs) 因其环境友好和成本效益高的特性而对提高石油采收率 (EOR) 产生了相当大的兴趣,因为硅化合物是自然界中砂岩和粘土的主要组成部分。NPs 可以通过多种机制增加石油产量,这些机制与高表面积和纵横比有关。EOR 方法通常会影响微观和宏观的扫描效率,NPs 对这两种现象都有很大的影响。本文综述了硅基纳米颗粒对多孔介质润湿性改变、油和纳米系统之间的界面张力、生产和注入流体的粘度、防止沥青质沉淀和孔道堵塞的影响。除了,它比较了纳米系统与玻璃微模型和岩心注水之间的采油率。值得一提的是,纳米流体/油/岩石性质的影响包括纳米颗粒的大小和浓度,岩石的类型、孔隙度和渗透率,油的密度和粘度,基液的盐度类型和浓度,以及压力等实验条件、温度等已经对每个机制进行了综合分析。
