摘要

颗粒间液桥引起的毛细黏聚作用广泛存在于自然界和工程应用中，其具有胶结作用，使颗粒聚集。研究毛细黏聚颗粒在裂隙介质中的运移-堵塞过程，对于理解颗粒传输过程具有重要意义。通过可视化试验，探讨了粗糙裂隙中毛细黏聚颗粒的运移-堵塞过程，提出了堵塞模式试验相图。结果表明，毛细黏聚作用使颗粒聚集成团，粒径增大，从而显著促进裂隙堵塞，并且运移-堵塞过程在高流速下为条纹堵塞模式，低流速下为完全堵塞模式或入口密封模式。水动力学分析显示，流速分布控制着堵塞条纹的生长及主要渗流通道的改变。此外，Smoluchowski理论能够较好地描述堵塞条纹随时间的线性增长规律。研究成果为评价和控制裂隙中颗粒运移-堵塞过程提供了理论依据和技术思路。
