sand pack

基本解释

Flowing performance of polymer solution with in-situ generated dispersed foam in sand-pack was tested at 60(C.
研究了60℃条件下，自生分散式泡沫聚合物溶液在填砂模型中的流动特性。
It is found experimentally that at a given saturation nonwetting permeabilities for an unconsolidated porous medium (sand pack) are higher than the drainage permeabilities.
实验结果发现，非湿相在非胶结岩心中的吸吮过程渗透率大于驱替过程者；
Using the sand pack model, the percolation features of low permeability cores with various clay minerals and different proportions of clays are studied under different fluid injection patterns.
通过室内填砂管渗流实验，研究了不同粘土类型、不同粘土比例的低渗透岩心在不同流体注入方式下的渗流特性，并根据实验结果分析了其渗流机理。
