    • Disclosed are methods for simulating pressures and saturations of oil, gas, and water in an oil reservoir with production and injection wells, which include (1) using of new approximating linear algebraic (finite difference) equations that more accurately represent actual pressures by basing the equations on new functional forms: ln(r) or 1/r, (2) solve the set equations using by defining a coarse grid array and a fine grid array nested in the fine grid array, and solving the coarse grid array and using the resulting solution to fix points in the fine grid array before it is solved, and (3) defining and solving a dynamic grid array based upon constant saturation contours.
    • 公开了用于模拟具有生产和注入井的油藏中的油,气和水的压力和饱和度的方法,其包括(1)使用新近似线性代数(有限差分)方程,其更准确地代表实际压力,基于 新的函数形式的方程式:ln(r)或1 / r,(2)通过定义粗网格数组和嵌套在精细网格数组中的精细网格数组求解集合方程,并求解粗网格数组,并使用 得到解决方案,在解决精细网格数组之前修复点,以及(3)基于恒定饱和轮廓定义和求解动态网格数组。
