老化对水溶性疏水缔合聚合物流变行为的影响
Rheological Behavior of Water-Soluble Hydrophobically Associating Polymer Affected by Aging
摘要
Abstract
AP-P4 solution was prepared by shear thinning of water-soluble hydrophobically associating polymer AP-P4 as an oil displacement agent in Bohai oil field water.The rheological behavior of AP-P4 solution was studied by static and dynamic experiments.The viscosity,viscoelasticity,and activation energy of viscous flow of AP-P4 solution in different aging time were investigated.The results indicate that when shear stress is moderate,AP-P4 solution exhibits shear thickening at low shearing rate and shear thinn at high shear rate in aging time less than 500 h.When shear stress is greater than critical shear stress,both the storage modulus(G') and the loss modulus(G") of AP-P4 solution decrease sharply with the increase of the shear stress in different aging time.When the shear stress remains unchanged,with increasing aging time,the power law index of G' first increases,then decreases,and finally keeps stable,while the power law index of G" keeps increasing.The activation energy of viscous flow of AP-P4 solution decreases with increasing shearing rate in the range of 25-45 ℃.关键词
