摘　　要：假定射孔中流体流动为管流,储层渗流遵从达西定律,基于流固耦合力学原理,建立储层渗流和射孔内流体管流的耦合模型,储层流体渗流和大孔道管流之间通过压力和流量关系进行耦合,并运用COMSOL Multi-physics软件进行数值模拟,为疏松砂岩油藏开发等提供理论指导。Based On mechanical schematics, a coupled mode of perforation reservoir fluid seepage and big channel flow is built. The software of COMSOL multi-physics is used to analyse the example. The mode of perforation reservoir seepage is based on Darcy＇ s law, and the flow in by channel is treated as pipe flow. The coupled relations between seepage and pipe-flow are based on pressure and flux conditions. The coupled theory between big channel and reservoir fluid flow can be used to exploit oil and gas.
