摘要/Abstract

摘要： 缝洞型油藏具有各向异性、介质尺度变化范围广及流动机理复杂等特点，因此数值模拟计算量大、计算过程复杂。基于异构并行架构建立分布式并行雅各比矩阵组装和GPU并行线性方程组求解，实现CPU-GPU异构并行的多重介质模型。对塔河油田不同规模的3个单元的实验结果表明，提出的异构并行算法具有较好的加速效果，随着CPU核数增加并行矩阵组装呈现出较好的可扩展性，数值模拟结果和串行程序模拟结果基本一致。

Abstract:

Fractured-vuggy reservoir has the characteristics of anisotropy, wide range of medium scale changes, and complicated flow mechanism. Therefore, the numerical simulation has a large calculation amount and a complicated calculation process. Based on the heterogeneous parallel architecture, we establish the distributed parallel Jacobi matrix assembly and the GPU parallel linear equation solver, in order to achieve the CPU-GPU heterogeneous parallel multi-media model. The experimental results on three units of different sizes in Tahe Oilfield indicate that the proposed heterogeneous parallel algorithm has good acceleration effect. As the number of CPU cores increases, the parallel matrix assembly exhibits good scalability, and the simulation results are almost the same as the serial program simulation results.

Key words: fractured-vuggy reservoir, oil numerical simulation, multi-media model, heterogeneous parallel
