随着国内油气田开发进程的加快，传统油田化学材料难以适应日益复杂化的井下作业环境。pH响应材料能够在井下酸碱环境的刺激下做出响应，从而发生自身结构、表面性质等方面的变化，继而更好地适应井下环境，以满足油气钻采作业需求。文章简要分析了pH响应材料的作用机理，并综述了以表面活性剂和聚合物为主的pH响应材料在钻井流体、化学驱油和压裂液中的响应机理和研究现状。

With the acceleration of domestic oil and gas field development，it is difficult for traditional oilfield chemical materials to adapt to the increasingly complicated underground working environment. However，pH-responsive materials can respond under the stimulation of underground acid-base environment，so as to change their own structure and surface properties，and then better adapt to underground environment to meet the needs of oil and gas drilling and production operations. This paper briefly analyzes the action mechanism of pH responsive materials，and reviews the response mechanism and research status of pH responsive materials based on surfactants and polymers in drilling fluids，chemical flooding and fracturing fluids.
