摘要
通过室内流变实验和渗流流变特性实验,研究了可动凝胶体系的流变特征,分析了可动凝胶体系的损耗模量和储能模量的量值变化关系,阐明了可动凝胶体系的粘弹特性及触变性。根据实验和非牛顿流变学理论,建立了多参数粘弹-触变性本构关系,并在实验和应用中得到验证。模型计算结果与实验数据相吻合,本构方程的稳定性较好。
The porous flow features and regular pattern of weak gel system were promulgated by rheometry and porous flow experiments in laboratory. The relations of loss modulus with storage modulus of weak gel system were discussed. The viscoelasticity and thixotropy of the system were analyzed. The constructive equations of viscoelasticity and thixotropy with multiple parameters were established and used to describe the hysteresis loops of weak gel flooding. The data calculated by the model accorded with the data from experiments. The constructive equations have good suitability.
