摘要
通过室内实验研究了驱油黏弹性表面活性剂(VES-JS)溶液的流变模式、剪切流变性、增黏性和黏弹性。研究结果表明,VES-JS溶液符合假塑性流体流变特征;在低速剪切下表现出"剪切变稀"的非牛顿特征;溶液浓度大于4 500 mg/L后表现出明显的增黏性;随着溶液浓度增大,其抗剪切能力和黏弹性越强。VES-JS溶液胶束结构的稳定性受温度影响较大。
The rheological model,shear rheological property,viscosity increasing property and viscoelasticity of viscoelastic surfactant solutions for oil displacement were studied in laboratory experiments.According to the results of study,Solution VES-JS has the rheological characteristics of pseudoplastic fluid,it exhibited the non-Newtonian character of ＂ shear thinning＂ at low speed shearing condition and apparent viscosity increasing capacity when the concentration of solution is greater than 4 500 mg/L.Both the anti-shearing capacity and the viscoelasticity of solution become stronger as the concentration of solution increases.The stability of the micellar structure of Solution VES-JS can be affected by temperature significantly.
