摘要
本文给出了柱坐标下黑油模拟问题的全差分求解方法,非对称的线性代数方程组采用Z方向的线逐次超松驰迭代解法。该求解途径现已发展成商业软件VIP黑油模拟器的一个解法选件,数值算例显示,求解结果符合油藏渗流规律,成功地模拟了0°和360°交界面处的流动问题。
This paper introduces a full differenec solution to black oil simulation under cylindrical coordinate system,and a linear successive over relaxation iterative solution in Z direction is used for asymmetric linear algebraic equation, This solution method has been one of solution options of black oil simulator, and numerical computation display and results correspond to the seepage flow law of oil reservoir,which successfully simulated flowing problem at intersection of 0℃and 360℃.
