对乳化酸和滤失控制酸在碳酸盐储层酸化中的特性认识

An Understanding of the Characteristics of Emulsified and Loss Control Acid in Carbonates Acidizing

摘要: 乳化酸和滤失控制酸是适用于碳酸盐储层深度改造的两种工作液体系，既可用于基质酸化，也可用作酸化压裂。通过分析酸液组成、缓速性能、流变性能、提高渗透率、注入时的压力回应等实验室测试结果，对比说明了两种酸液体系在碳酸盐岩储层中的反应特性。

Abstract: Emulsified and loss control acid are two systems to generate deeply penetrating wormholes in carbonate formations. They can be used in the field both for matrix and fracture acidizing. In this paper, the reaction characteristics of emulsified acid are co
