摘要

本文在深入研究迭代解法的基础上,对全隐式油藏模拟形成的线性代数方程组进行了预处理方法、节点排序方法等求解方法的优化,优化出适于并行的最佳解法.以优化后的预处理正交极小化算法为基础,对多层二维二相全隐式模拟模型进行了以层为单位的粗粒度并行任务划分.油田大规模实例计算表明并行化的多层二维二相全隐式模拟模型形成的软件具有较高的并行效率,满足油田实际应用的需要.

Abstract

The paper optimizes the pretreatment method of the matrix and the compositor method of the nods etc about the linear algebra equation group formed by full-implicit reservoir simulation and produce the best solution fitting for parallel on the base of deep reserch about iterative solution.At the base of optimized ORTHOMIN method,the two dimension two phase full-implicit model with muti-layers has been paralleled as coarse granularity.The calculating outcome of large scale reservoir simulation indicates that the paralleled muti-layer two dimension two phase model possesses upper parallel efficiency and meets the practical application demands of the oilfield.
