Abstract: An integral type constitutive equation for elastico-viscoplastic liquids has been proposed to describe the rheological properties of sesbania gel as a fracturing fluid in oil recovery. The rheological parameters determined by steady shear flow were used to analyse the oscillatory shear flow and die-swell flow. The theoretical analysis agreed with the experimental data. The equation can also be used to predict the rheological properties of xantham gum and HPG gel.
摘要: 以石油开采过程中常用的田菁凝胶压裂液为体系,导出了一个描述粘弹塑性流体流变性质的积分型本构方程.通过稳态测粘流实验得到了方程的参数,并利用本构方程分析了小振幅振荡流和挤出胀大流.实验表明,方程计算值能够较好地与实验结果相吻合.同时,利用此本构方程对黄原胶、瓜胶的流变性质进行的分析表明,该方程也适用于这两种凝胶,具有一定的通用性.
