[0002] Oilfield wellhead electromagnetic heating is a technology that uses electromagnetic fields to heat fluids. It is mainly used in the production and maintenance of oil and gas wells to improve the fluidity of oil and gas, prevent pipeline blockage, and extend the life of the well. Wellhead electromagnetic heating devices are generally composed of power supplies, controllers, electromagnetic coils, and insulation layers. The power supply provides current to the electromagnetic coils, which generate electromagnetic fields. The electromagnetic fields heat the fluids, and the insulation layer maintains the temperature of the fluids.
