摘　　要：油砂开采面临的最大挑战是尾砂的处理以及如何提高尾砂油的回收率。结合国内外最新研究及实践成果,总结了尾砂的沉降、脱水、脱油和废弃物的处理方式,以及可用于提高尾砂油回收率的表面活性剂、碱剂、热解、超声波等方法,为尾砂的无害化处理提供了理论参考。The challenges in oil sand exploitation are the treatment of tailings and how to increase the tailing oil recovery rate. Based on the latest research and application results at home and abroad, the technologies for tailing sedimentation, dewatering, oil-removing and waste disposition are summarized, and the methods for increasing of tailing oil recovery rate by surfactants, alkaline reagents, pyrolysis and ultrasound wave are introduced. These provide theoretical reference for harmless treatment of tailings.
