摘要：Magnetic treatment is a widely physical technique used in oilfields. The effects of magnetic field on waxy crude oil emulsion have drawn much attention. This study aims to explore the relationship of the change of viscosity of emulsion and magnetic treatment conditions and viscosity reduction mechanism. The static permanent magnet device was constructed. The viscosity of crude oil and emulsion, oil–water interfacial tension and the distribution characters of emulsion droplets before and after magnetic field were experimentally studied. The results showed that when the magnetic treatment temperature was wax appearance temperature, the magnetic field intensity of 200 mT and magnetic treatment time of 10 min, the viscosity of emulsion decreased the most and reached 14.5%. Meanwhile, the viscosity of crude oil and oil–water interfacial tension decreased after magnetic treatment. The droplet distribution did not change obviously after applying different magnetic treatment conditions. The magnetic field reduced the viscosity of the emulsion by reducing the viscosity of crude oil and the oil–water interfacial tension. ? 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
