摘要: 泡沫可以帮助酸转入低渗透或更需要酸化的地层中来优化酸液置放。泡沫分流酸化模型是在泡沫驱模型基础上发展起来的。目前主要的泡沫分流酸化模型有:基于分流理论的临界毛管压力模型,气泡总量关系模型和Robert-Mack模型。概况了泡沫分流酸化的模型,对比了各模型的优缺点,并提出了今后发展更完善合理模型所需做的进一步工作。

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
