摘　　要：根据国内外关于泡沫体系渗流机理研究结果 ,以三维四相多组分模型为基础 ,建立了一个基于泡沫气泡数量平衡的泡沫功能模型。将该模型与一个三维四相多组分的化学驱模型相结合 ,构造了一个泡沫复合驱数学模型。应用该模型进行了泡沫复合体系的岩心驱模拟研究 ,结果表明 ,渗透率变异系数为 0 .72时应用泡沫复合驱提高采收率幅度最大。According to the research result of percolation mechanism of foam system arisen both at home and abroad, a foam function model based on the quantative balance of foam bubbles is established on the basis of a multicomponent model. A mathematical model for composite foam flooding is established by combining the model with a 3 dimensional and 4 phase chemical flooding model. A core flooding simulation study of foam composite system is conducted by using the math model, the result demonstrates that the amplitude of EOR of the composite foam flooding is maximum when permeability variation coefficient is at 0. 72.
