摘要: 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。通过对比相同聚合物浓度下的普通聚合物溶液和自生分散式泡沫聚合物溶液在填砂模型中的流动阻力发现,后者具有良好的流度控制能力。并联填砂模型初步实验结果表明,它能有效地改善聚合物溶液在渗透率严重非均质地层中的流动特性,有利于提高其波及效率。

Abstract: Flowing performance of polymer solution with in- situ generated dispersed foam in sand-pack was tested at 60(C. By comparing the flow resistance of this kind of fluid with general polymer solution, it was found that, the polymer solution with in-situ generated dispersed foam has good polymer solution in
serious permeability heterogeneous reservoir, which is beneficial to improve oil recovery.
