AI Technical Summary
Existing wellhead heating equipment for oil production is inefficient, energy-intensive, lacks explosion-proof performance, and has poor environmental adaptability, posing safety hazards from open flames and having a short equipment lifespan.
It adopts an electromagnetic heater and electromagnetic coil heating method in an explosion-proof enclosure, combined with an insulation layer and a temperature sensor. It heats crude oil medium through electromagnetic induction eddy currents, and uses the electromagnetic heater to realize PID automatic temperature regulation. It is equipped with a control module and explosion-proof structure to ensure safety.
It achieves efficient, safe, and reliable heating with precise temperature control, energy savings of 30-50%, longer service life, avoids safety hazards caused by open flames, and is adaptable to extreme wellhead environments.
