Abstract: Foam can efficiently divert acid into low-permeable and population formation to optimize acid placement. Foam diver-sion acidizing model has been developed form foam displacement simulation. The model currently includes critical capillary pres-sure model based on fractional-flow theory, bubble population
correlation and Robert-Mack model. Present foam diversion model in matrix acidizing are presented in this paper and further work and improvement in this field are discussed and put for-ward.

Key words: foam diversion, trap, critical capillary pres-sure, diversion model
