中文摘要：

在清洁水渗流实验的基础上,开展了恒水头条件下不同浓度的含悬浮颗粒流体在多种填充粒径的多孔介质内的渗流实验。结果表明：悬浮颗粒在多孔介质段的沉积,并不一定使多孔介质局部相对渗透系数（k_t/k_0）降低,相反在一定情况下会出现局部相对渗透系数增大的情况。较小悬浮颗粒浓度下,悬浮颗粒粒径越小,曲线波峰出现越迟,相对渗透系数增加幅度越大;而较大进口浓度则抑制（k_t/k_0）曲线波峰的生成,直至相对渗透系数单调递减。通过包括前人实验数据在内的悬浮颗粒浓度C_0与颗粒直径比值d_p/D_p（悬浮颗粒直径/多孔介质颗粒直径）有无相对渗透系数增加现象的对照图,进一步揭示了含悬浮颗粒流体在多孔介质内的运移与沉积规律。

英文摘要：

Experiments of different concentrations of carrier fluid flow in porous media with various filler particle sizes were conducted based on the clear water seepage experiment. The results show that the micro-particle deposition do not necessarily decrease the local relative permeability kt/k0 of porous media, on the contrary, increases kt/ko under certain conditions, and a wave crest occurs and propagates downward dynamically. For small concentrations of carrier fluid, the smaller the particle size, the later the wave crest appears, and the larger the kt/k0 increases, whereas the wave crest will be inhibited by the larger concentration of carrier fluid, until kt/k0 monotonically decreases. In addition, the accumulated deposition characteristics of the suspended particles during the reinjection process were investigated.
