摘要
本文建立跃变型介质中原油渗流的数学模型,可用来描述油层(尤其是低渗透层)超高压注水条件下的不稳定渗流过程及其特征。用Galerkin有限元法进行了数值计算,讨论了介质跃变的影响。
This paper establishes a mathematical model for non-linear flow through leap media. The model can be used to describe the characteristics of flow through media with permeability leap due to rock fractured under the condition of super-high-pressure water injection. Numerical analysis is done with Galerkin's finite element method, and its results arc discussed.
