PRELIMINARY DISCUSSION ON FRACTAL MODEL OF ACID-ROCK REACTION

-
Abstract
Pickling of rock is an important problem in acidizing of oil and water wells.According to the acid-rock reaction controlled by diffusion mass transfer and surface reaction,this paper presents 2D model of acid-rock reaction by applying the new theory of mathemetics-fractal in acid-rock heterogeneotis reaction system,and then analyses the influence of complex structure of rock grain on pickling rate to a certain extent.
