摘　　要：为了更准确地分析剩余油,搞好特高含水后期的调整挖潜,需要超大模型数值模拟提供技术支撑。采用两步预处理方法提高模拟器运算能力,按照模型分割与回填的方式建立超大模型历史拟合方法。应用实例表明,新构建的求解器具备了千万级节点运算能力,模型分割与回填的方法适合于超大模型的历史拟合。In order to analyze the remained oil more accurately,it is necessary to provide the technical support for the super large-scale numerical simulation to do well in the adjustment and potential tapping in the later period of the high watercut. The two-step pretreating method was used to enhance the computing capability of the simulator,and moreover the history fitting method of the super model was established according to the ways of the model segmentation and backfilling. The applied case shows that the newly constructed solver has the capability of ten million node operation,and the method of the model segmentation and backfilling is suitable for the historical match of the super model.
