| 摘 要： | 经岩心流动实验证实,岩心经纳米颗粒吸附法处理后,水流速度加快,岩心的水相渗透率有了大幅提高,平均达到82%。采用Forchheimer-Darcy模型描述岩心微孔道内的流体流动特征,建立了多孔介质表征体单元(REV)尺度上的不可压Lattice Boltzmann(LB)压力模型,编制了修正反弹格式的LB模拟程序,模拟了多块岩心的渗流效果,计算了纳米颗粒吸附法处理前、后的相关流动参数。数值模拟结果与实验结果吻合较好,说明LB压力模型适合模拟多孔介质的流动,在纳米增注渗流机制研究方面将有很好的应用前景。

| Abstract: | The results of the core displacement experiments show that,after treatment with Hydrophobic Nanoparticles(HNPs),the fluid velocity was increased and the water-phase effective permeability(WPEP) was increased about 82 percent averagely.The characteristics of water flow through the microchannels in cores are described as Forchheimer-Darcy model.A incompressible Lattice Boltzmannn(LB) method,which is at the representative elementary volume(REV) scale of porous media,was established also.A LB simulation program... |
