缝洞型碳酸盐岩油藏并行模拟器及其应用研究
A Parallel Reservoir Simulator for Fractured-Vuggy Carbonate Reservoirs
摘要
Abstract
To meet the requirement of large-scale fine reservoir simulation in the unconventional reservoir,we have developed a KarstSim parallel reservoir simulator based on its successful application in fracturedvuggy carbonate reservoirs.There are mainly three steps to implement this simulator,grid domain partitioning,assembly and solution of linearized equation systems and communication between processors.Also we have utilized Aztec package and METIS software to complete KarstSim-MP.The Buckley-Leverett two phase vertical flow model and a block model in Tahe Oilfield are simulated to compare the analytical solution with the numerical solution and PC to parallel solution.The study verifies the accuracy of the parallel simulation result and effectively enhances computational efficiency.The simulation was conducted of the heterogeneous fractured-vuggy reservoir with 640 thousand scale grids.The simulation time can reach to 7.3 hours with the 128 CPUs and the computational efficiency increased obviously.The simulation of different scales of homogeneous reservoir produced the computational efficiency rising from 10 thousand to 10 million.The results show the simulation time will decrease to 85 minute and will effectively increase computational efficiency for its application in large scale reservoir simulation.关键词
