摘　　要：疏水缔合聚合物在提高采收率领域中展现出巨大应用潜力,但其疏水基团结构特征使溶解性成为关注焦点。综述了近年来疏水缔合聚合物高效溶解的研究进展,分析了面临的挑战及未来的发展方向。重点介绍了添加化学试剂屏蔽疏水基团的缔合作用,采用筛网切割和胶体研磨等方式增加水与聚合物颗粒的接触面积,以及通过改变聚合物自身溶解性、提高溶液质量浓度或温度、优化搅拌器类型及搅拌方式以增大体系熵变等方法加速疏水缔合聚合物的溶解。化学方法虽然能够快速溶解疏水缔合聚合物且不损害其性能,但其使用成本和环境影响仍需考量。而物理方法尽管经济有效,但可能导致溶液的机械降解和热降解,进而影响增黏性能和驱油效果,同时还需要解决机械设备的运输、能耗以及空间限制问题。因此,研发新型环保溶剂和优化工艺设备对于实现疏水缔合聚合物高效溶解具有重要意义。此外,综合考虑多种高效溶解方法的协同作用,依据实际应用情况进行调整,以期扩大疏水缔合聚合物的规模应用。Hydroobically associating polymers demonstrate significant potential in enhancing oil recovery,yet their hydrophobic group structure has brought dissolution characteristics to the forefront of research.This review encapsulates recent advancements in the efficient dissolution of hydrophobically associating polymers,and analyzes the challenges encountered and future directions.It highlights strategies such as employing chemical agents to mask the associative effects of hydrophobic groups,using methods like screen cutting and colloidal milling to increase contact area between water and polymer particles,and accelerating polymer dissolution through altering intrinsic solubility,increasing solution mass concentration or temperature,and optimizing mixer types and agitation methods to enhance system entropy change.While chemical approaches enable rapid dissolution without compromising polymer performance,considerations regarding cost and environmental impact remain.Physical methods,though economically efficient,may lead to risk mechanical and thermal degradation of the solution,potentially diminishing viscosity enhancement performance and oil displacement efficiency.These methods also face challenges in equipment transportation,energy consumption,and spatial constraints.Therefore,developing new eco-friendly solvents and optimizing process equipment are critical for achieving efficient dissolution of hydrophobically associating polymers.Moreover,considering the synergistic effect of various efficient dissolution methods,adjustments will be made according to practical application scenarios,in order to expand the large-scale application of hydrophobically associating polymers in diverse fields.
