摘要
根据油藏矿场试验和室内实验测试资料,在研究非线性渗流规律基础上建立非线性渗流数学模型。将数学方程离散化、线性化,用预处理双共轭梯度法、预处理正交极小化法等方法求解线性代数方程组,建立非线性渗流的数值模型。开发的一套具有稳定性好、收敛速度快的"非线性渗流三维二相油藏数值模拟软件"能处理线性和非线性渗流2种模型,用经验公式和数值方法描述非线性关系拓宽了软件的应用领域。
According to the data of oil field testing and experimental study,the mathematical model and numerical model of non-linear flow were established that based on non-linear flow law.The software of three dimension(3D) and two phases reservoir simulation for non-linear flow has good stability,prompt convergence speed.It can solve linear flow and non-linear flow problem.It also can describe non-linear relationship using experience formula and numerical method.The solution of non-linear flow factor came from nume...
