摘要
本文以参考文献[1]中SPE考题设计的三维三相黑油模型的地层参数、PVT表及生产方式为模拟的依据,利用LSOR、SSOR-CG、ILU-CG及MILU-CG方法进行模拟,结果表明MILU-CG方法较LSOR快10倍,较ILU-CG也快约1倍。随着问题规模的增加,MILU-CG显得更有效,因此是油藏数值模拟中值得重视和推广的好算法。
Based on the rock and PVT data given in 1980's SPE comparative solution project we employ four methods: LSOR, SSOR-CG, ILU-CG, and MILU-CG to simulate a 3-phase black-oil model. The numerical result demonstrates that the CPU time used by the modified incomplete LU decomposition conjugate gradient method (MILU-CG) is about one tenth of that used by LSOR method, and is about half of that used by the general ILU-CG method. Furthermore, as the scale of a problem is concerned f the finer the mesh is, the more effcient the method will be.
