Nanofluid flow in porous media was modeled for enhanced oil recovery. The effects of parameters such as the matrix porosity, nanoparticles, and diffusion coefficients on the oil recovery factor were reported. The velocity, temperature, and oil saturation contours were examined. The study showed that the oil recovery and heat transfer were enhanced by the use of a nanofluid. A 30 % and 10 % increase in the oil recovery factor were found using the Al₂O₃-water nanofluid as compared to water and the polystyrene-water nanofluid, respectively. The temperature in the porous matrix was significantly reduced by the Al₂O₃-water nanofluid as compared to the polystyrene-water nanofluid and water. In the future, this model could be used to screen the performance of other chemical agents and eventually lead to a more efficient and sustainable oil extraction process.

使用纳米流体提高石油采收率的建模

对多孔介质中的纳米流体流动进行建模以提高石油采收率。报告了基质孔隙率、纳米颗粒和扩散系数等参数对采收率的影响。检查了速度、温度和含油饱和度等值线。研究表明，使用纳米流体可以增强采油和传热。发现与水和聚苯乙烯-水纳米流体相比，使用Al ₂ O ₃ -水纳米流体的石油采收率分别增加了30％和10％ 。与聚苯乙烯-水纳米流体和水相比， Al ₂ O ₃ -水纳米流体显着降低了多孔基质中的温度。未来，该模型可用于筛选其他化学试剂的性能，并最终实现更高效、更可持续的石油开采过程。
