为正确而有效地进行砂岩酸化设计和酸化效果预测,砂岩土酸酸化数学模型的建立和完善十分重要。本文通过模型评述,指出Hill毛细管模型和Hekim分布多数模型是迄今从微观和宏观角度提出的两种最基本的砂岩土酸酸化教学模型;通过模型考察,认为现有的有关模型均未能全面地反映出实际储层条件下的酸岩反应机理,而有必要对其作进一步的深入研究和完善。

In order to conduct exactly and effectively the designs of stimulation treatment and the predictions of acid posttreatment well response,it’s very important to present and perfect the basic mathematical models of mud acid/sandstone chemistry. Based on revlew on the literatures, it’s pointed out that Hill’s capillary model presented from microscopic view and Hekim’s distributedparameter model presented from macroscopic view are the most basic models of mud acid/sandstone chemistry so far. Based on investigation on the models, it’s concluded that the models existed at present don’t reflect exactly the mechanism of acid/rock heterogenous reaction and perfecting further the basic model mud acid/sandstone chemistry is necessary.
