【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。更多还原

【Abstract】 Foam can efficiently divert acid into low-permeable and population formation to optimize acid placement. Foam diversion acidizing model has been developed form foam displacement simulation. The model currently includes critical capillary pressure 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 forward.更多还原
