本文对油水两维两相渗流非线性模型给出了矩形剖分的线性平方插值两种有限元解法,就线性插值方法给出了反九点法注水开发的算例,结果令人满意。同时,对两种插值方法进行了分析比较。
In this paper, two finite element methods of square interpolation of rectangular section are given for the nonlinear model of two-dimensional oil-water two-phase seepage. An example of water injection with anti-nine point method is given for linear interpolation. The result is satisfactory. At the same time, the two interpolation methods are analyzed and compared.
