The use of nanomaterials as a means of recovering heavy and light oil from petroleum reservoirs has increased over the preceding twenty years. Most researchers have found that injecting a nanoparticle dispersion (nanofluids) has led to good results and increased the amount of oil that can be recovered. In this research, we aim to imitate the three-dimensional hexagonal prism in the existence of SiO2 and Al2O3 nanoparticles for better oil recovery. Porosity (), mass flow rate (), nanoparticle concentration (), and the effect of relative permeability (kr) on oil and water saturation in the presence of gravity under different time durations are all investigated. The result obtained for the model is verified with existing experimental data. The results indicated that the infulence of nanoparticle volume fraction (VF) is significant in enhancing the oil recovery rate. It is also observed that at low porosity values the oil recovery is maximum. The maximum oil recovery is attained at low values of mass flow rate in the 3D hexagonal prism in the presence of silicon and aluminium nanoparticles It is also observed that the use of SiO2 gives a better oil recovery rate than Al2O3. It is also observed that maximum oil recovery is obtained at 99% at a flow rate of 0.05 mL/min in the presence of silicon injection.
在过去二十年中，使用纳米材料作为从油藏中回收重油和轻油的手段有所增加。大多数研究人员发现，注入纳米颗粒分散体（纳米流体）已取得良好效果，并增加了可回收的油量。在本研究中，我们旨在模拟存在二氧化硅和氧化铝纳米颗粒时的三维六方棱柱，以实现更好的原油采收率。研究了孔隙率（）、质量流率（）、纳米颗粒浓度（）以及在不同时间段重力作用下相对渗透率（kr）对油水饱和度的影响。用现有的实验数据验证了该模型得到的结果。结果表明，纳米颗粒体积分数（VF）对提高原油采收率有显著影响。还观察到，在低孔隙率值下，原油采收率最高。在存在硅和铝纳米颗粒的三维六方棱柱中，在低质量流率值下可实现最大原油采收率。还观察到，使用二氧化硅比使用氧化铝具有更好的原油采收率。还观察到，在注入硅的情况下，当流速为0.05 mL/min时，最大原油采收率可达99%。
