Abstract
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.
