摘要
本文根据弹性不稳定渗流未简化的非线性扩散方程,引入了无量纲指数压力和无量纲产量系数。获得了考虑非线性项C_1|▽P|～2情形下的精确解(非线性解),研制出新的典型曲线图版,找出了非线性解与Agarwal-Ramey解(线性解)之间的关系,并进行了比较。最后用实例说明该典型曲线的应用。
In this paper the original nonlinear dispersion equation for the problem of unsteady- state fluid flow in porous media is considered. A dimensionless exponential pressure and di- mensionless rate factor are introduced. The exact solution is obtained by taking nonlinear term C_i|▽p|~2 into consideration. A new set of type curves is built up. The nonlinear solu- tion and Agarwal-Ramey solution are compared. An example is included to illustrate the use of the type curves.
