利用串联平板夹砂渗流模型，研究了同粘度疏水缔合聚合物溶液在均质模型下的渗流特性。结果表明，在渗透率1.1~6.1μm2范围内，疏水缔合聚合物溶液在平板渗流模型中压力达到稳定的时间与疏水单体含量成正比；相同渗透率下，缔合聚合物在传播方向上的阻力系数和残余阻力系数呈增加趋势，且增加幅度与疏水单体含量成正比，而聚丙烯酰胺在介质中的渗流特性是不变的。采用微孔滤膜过滤方法，证明了疏水单体含量对渗流特性的影响在于其改变了溶液中聚集体尺寸。

A series flat sand percolation model were used to study the flow characteristics of different hy-drophobic monomer content of hydrophobic associating polymer solution at the same viscosity. The results show that in the permeability range from 1. 1 to 6. 1 μm2 ,the injection pressure’s stable time of hydro-phobic association polymer solution was proportional to the hydrophobic monomer content in this model. Under the same permeability,RF and RRF tended to increase in the propagation direction of hydrophobic associating polymer solution,and the rate of increase is proportional to the hydrophobic monomer content, but polyacrylamide flow characteristics in the medium is constant. Microporous membrane filtration method was used to prove the influence of hydrophobic monomer content for the flow characteristics lies in chan-ging the aggregate size of the solution.
