摘　　要：随着油田开采的不断深入,提高原油采收率面临着更大的困难和挑战,特别是在驱油体系的耐温抗盐能力和不可入孔隙体积等方面还存在较突出的问题。碳纳米流体是由碳纳米材料和溶剂(通常是水)组成的一种高效的工作介质,具有使储油孔喉发生润湿性反转、降低油水界面张力、形成分离压力和降低原油粘度等作用,在提高原油采收率中展现了巨大的应用潜力。国内外学者针对这一方向开展了深入的研究,并取得了一系列重要的成果,使碳纳米流体提高原油采收率成为原油开采的热点并有望在未来得到迅速发展。本文介绍了碳纳米流体的驱油机理,重点总结了碳量子点、碳纳米管、石墨烯以及氧化石墨烯等碳纳米材料所构建的碳纳米流体在提高原油采收率中的应用进展,并对其未来的研究趋势进行了展望。With the development of oil extraction, enhanced oil recovery still has obstacles and difficulties, especially in the temperature resistance, salt tolerance, and impermeable pore volume of the oil displacement system. As an effective working medium composed of carbon nanomate- rials and solvent (e.g water), carbon nanofluid could cause the wettability reversal of oil storage pore throat, reduce oil-water interfacial tension, form separation pressure, and decrease crude oil viscosity, showing great potential for application in enhanced oil recovery. In recent years, considerable progress has been made in this area. As a result, carbon nanofluid has emerged as a research hotspot in oil extraction and is planned to get quick advancement in the future. Herein, the oil displacement mechanism of carbon nanofluids is described, and the applications of carbon nanofluids are constructed from carbon quantum dots, carbon nanotubes, graphene, and graphene oxide in enhanced oil recovery are summarized. Finally, the challenges for the future development of carbon nanofluids are also briefly proposed.
