摘要： 将一系列沉淀剂、 凝胶剂用于流动实验, 研究了介质渗透率和原油饱和度对渗流特性的影响。结果 表明, 高效的堵水调剖剂可以选择性的降低非均质多孔介质的渗透率, 即最大程度地作用到高渗储层和含有较低原 油饱和度的区域。该特性与体系中聚合物颗粒或者胶体粒子的存在有关, 并从胶体化学角度提出了阐释调剖剂选 择性调节非均质储层渗透率的作用机理。

Abstract: Cores experiments were conducted to study the effect of permeability and oil saturation of porous media on the characteristics of a number of plugging/profile modifying compositions. The results show that the effective plugging/profile modifying compositions are capable of selectively reducing the permeability of heterogeneous porous media by the greatest influence on the permeability of porous media, which has high water permeability and minimum oil saturation. It is found that the ability of compounds to selectively influence on the permeability of porous media is related to the presence of polymer globules or colloidal particles. Colloidchemical mechanism is proposed to explain the ability of profile modifying agent to selectively regulate the permeability in heterogeneous reservoir.
