摘　　要：胶凝酸是常见的缓速酸液体系,广泛用于碳酸盐岩储层酸化压裂增产作业中。稠化剂是增加酸液黏度、保证胶凝酸性能的关键。本文回顾了胶凝酸稠化剂的研究历程,综述了近年研究进展,重点对其分子结构设计、合成以及所制备的胶凝酸性能和现场应用效果进行了归纳与分析,评述了不同类型酸液稠化剂的特点及优劣势,探讨了稠化剂的优化设计及性能提高等问题,指出了目前面临的挑战,并展望了未来的发展方向。Gelled acid is a common retarded acid system,which is widely used in acidizing and fracturing operations to enhance oil and gas production for carbonate reservoir.The key of gelled acid is the polymer thickening agent,which can impart the acid solution high viscosity and good performances,thus the research of thickener has gained intense attention during the past decades.In this article,we reviewed the research history and recent advances of thickener in this area,and particularly focused on the molecular structure design and preparation of thickener,the performances and practical applications of corresponding gelled acids.Moreover,the advantages and disadvantages of different thickening agents were discussed,and a special attention was given to discuss the strategy that how to optimize the molecular structure of thickener and improve the performances of the gelled acid.Furthermore,we also discussed the challenges that concern the future development of gelled acid.
