通过岩心模拟流动实验，在相当宽的流速范围内，测定了高分子量聚丙烯酰胺（HPAM）溶液在70℃油层温度下通过油藏岩石流动时的稳态压力降与流速的关系曲线，从而揭示了HPAM溶液在多孔介质中的复杂双重流变特性：在低速下呈剪切变稀的假塑性，在高速下出现剪切增稠的粘弹性。将流变仪测得的流变性和获得的本体流变模型引入描述多孔介质的毛细管束模型，从而把达西公式推广到了幂律流体。合理修正了Hirasaki的视剪切速率表达式，获得了多孔介质的视剪切速率与达西流速之间的关系式，进而建立了HPAM聚合物溶液的地下流变模型。
Through the core flow simulation experiment, the steady-state pressure drop of the high molecular weight polyacrylamide (HPAM) solution flowing through the reservoir rocks at 70 ℃ reservoir temperature was measured to reveal the relationship between the flow rate and the flow rate over a wide range of flow rates The complex dual rheology of HPAM solution in porous media: pseudoplasticity of shear thinning at low speeds and shear-thickening viscoelasticity at high speeds. The rheology measured by the rheometer and the obtained ontology rheological model were introduced into the capillary beam model describing the porous media, thus the Darcy formula was generalized to the power law fluid. The apparent shear rate expression of Hirasaki was corrected reasonably, and the relationship between the apparent shear rate of porous media and Darcy flow rate was obtained. Then the underground rheological model of HPAM polymer solution was established.
