摘　　要：阐述了目前油田现场使用过的三种变黏酸(聚合物温控变黏酸、聚合物pH值控制变黏酸、黏弹性表面活性剂pH值控制变黏酸)的基本原理及发展概况。并通过分析三种变黏酸存在的缺陷,提出了变黏酸今后的研究方向。The basic principles and development overview of three types of variable viscosity acid were described in this article. These variable viscosity acid（temperature controlled polymer variable viscosity acid, pH-controlled polymer variable viscosity acid, pH controlled visco elastic surfactant variable viscosity acid） had been applid in the oil field. The research direction for variable viscosity acid was proposed according to analysis of the defects of three types of variable viscosity acid.
