The Determination of Acid-Rock Reaction Kinetic Equation With Deep-Penetration and Low-Damage Acid

摘要

Deep-penetration and low-damage host acid is composed of two kinds of organic acids, two kinds of inorganic acid and necessary organic additives, and the concentration is 16%. It is a kind of acid liquid system which has a strong versatility, less damage to the formation, strong acid rock reaction rate, high final dissolution rate, and organic inorganic scaling. In order to determine the reaction rate of the acid and the reaction kinetics equation of deep penetrating low damage acid, the acid rock reaction rate of common acid and deep-penetrating and low-damage acid is studied.
