Abstract

Abstract: The acid solution capacity and solution behavior are tested for the carbonate rocks in Feixianguan，Jialingjiang and Changxing Formations in Pu guang gas reservoir.Acid/Rock reaction kinetics is investigated by using rotating disk system.The experimental results show that acid/rock reaction characteristics and reaction kinetics equation have an apparent difference in different formations because the components of rocks are heterogeneous.The characteristics of acid/rock reaction is studied carefully in this paper and it is important that the research results can be applied for acidizing design for gas reservoir in northeast Sichuan.

Key words: Carbonate rock, Acidizing, Solution behavior, Rotating disk, Reaction kinetics
