建立了圆形有界地层中非牛顿幂律流体渗流边界定压和封闭两种模型，求得了拉氏空间中的解，做出了理论图版，进行了实例研究。本文的研究可用于聚合物驱等非牛顿渗流条件下的试井解释。
Two kinds of models of constant pressure and seal of non-Newtonian power-law fluid percolation boundary in circular bounded formation are established. The solution in Lagrange space is obtained. The theoretical plate is made and an example is given. The study in this paper can be used for well test interpretation under non-Newtonian seepage conditions such as polymer flooding.
