摘　　要：水力压裂技术的面世使得油气井的产能得到了显著提升,成为非常规油气资源开发的重要手段。然而,在水力压裂措施实施的同时会出现支撑剂回流的现象,对措施后的测试以及生产造成影响,还可能削弱压裂措施的增产效果。本文介绍了影响支撑剂稳定性的因素,重点分析了造成支撑剂回流的原因,并综述了现有控制支撑剂回流的方法、原理以及现场应用情况。针对于不同的储层、地域情况应选择合理的控制回流方法以保证压裂后的增产。展望未来,压裂支撑剂的发展前景广阔,预计将朝向高性能、智能化、可降解及多功能的方向发展,同时也要注意到对环境带来的潜在影响,朝着更可持续的方向发展。The advent of hydraulic fracturing technology has significantly increased the productivity of oil and gas wells and has become an important means to develop unconventional oil and gas resources. However, proppant backflow can occur during hydraulic fracturing, which can interfere with post-fracturing testing and production and can reduce the stimulation effectiveness of fracturing. In this paper, the factors affecting proppant stability are introduced, the reasons for proppant reflux are analyzed, and the existing methods, principles and field applications of proppant reflux control are reviewed. According to the different reservoir and regional conditions, we should choose reasonable reflux control methods to ensure the production increase after fracturing. Looking ahead, the development of fracturing proppants is promising and is expected to move towards high performance, intelligent, degradable and versatile, while also taking into account the potential impact on the environment and moving towards a more sustainable direction.
