摘　　要：对川东北普光气田飞仙关组、嘉陵江组、长兴组碳酸盐岩进行了酸—岩溶蚀性试验和酸—岩刻蚀形态实验。并采用旋转岩盘仪,进行了碳酸盐岩酸—岩反应动力学研究。结果表明,不同的碳酸盐岩储层,由于岩石矿物的非均质性,造成酸对碳酸盐岩的溶蚀性和酸—岩刻蚀形态具有明显的差异,导致酸—岩反应速度不同,因此所建立的反应动力学方程也不同。实验成果完善了川东北区块碳酸盐岩储层酸—岩反应特征研究,为川东北碳酸盐岩储层现场酸化工艺设计和决策提供了科学依据。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.
