摘要
建立三维三相渗流数学模型,构造该模型的有限差分离散化方法,确定考虑非线性渗流的井—网格流动方程,编制三维三相非线性渗流数值模拟软件。最后选取某油藏参数检验模拟软件的准确性。
3D and three -phase nonlinear flow model is set up for the first time, and a corresponding finite defer- ence discretization method for this model is also developed, then a well - grid folw equation to simulate nonlinear flow is deduced. Based on the above, the 3D and three -phase nonlinear flow simulator is established. At last, reservoir parameter is used to check the accuracy of the software.
