摘要
裂缝型碳酸盐岩油藏非均质性极强,数值模拟运算时间长,迫切需要一种切实可行的解决方法。介绍了区域分解法在数值模拟中的应用方法,提供了油藏数值模拟串行算法并行化的一般策略与方法。基于已开发的双重介质油藏数值模拟串行算法及建立的Windows平台PC集群网络并行计算环境,利用消息传递界面(MPI库)实现了并行过程中所有消息的传递功能。通过对国内某实际碳酸盐岩油田的模拟表明,并行后的算法是成功的,2个PC加速比高达1.86,4个PC达到3.46,8个PC达到6.89。通过模拟还发现,并行数值模拟时,存在最佳的子区域规模和数目。该算法解决了大规模碳酸盐岩油藏数值模拟时间长的问题,具有实际的应用价值。
The heterogeneity of fractured carbonate reservoir is very strong.The simulation of the dual-porosity reservoir spends a lot of time,so it is urgent to find a method to solve it.In this paper,the application of domain decomposition in reservoir simulation is introduced.A strategy is introduced on parallel serial software.Based on the parallel computing environment on PC clusters with Windows OS and the developed dual-porosity reservoir simulator,a message passing interface (MPI) library is adopted for all messages passing functionality.Numerical tests for a carbonate Oilfield are performed on PC clusters,the speed-up ratio of 2 PC clusters is 1.86,3.46 for 4 PC clusters,and 6.89 for 8 PC clusters respectively.The result shows that the parallel simulator has extensive applicability and really saves a lot of time for the large scale carbonate reservoir simulation.
