AI Technical Summary
Existing heating devices for heavy oil wellheads suffer from low heating efficiency, high energy consumption, and difficult management. They are particularly inadequate for meeting heating requirements when the well gas content is low, and the energy-saving and emission-reduction effects of electric heating furnaces are not ideal.
The heating method uses a combination of induction coil and outer cylinder. The induction coil is fitted on the outer wall of the outer cylinder. An alternating magnetic field is generated by alternating current to produce eddy currents on the outer cylinder, thereby rapidly heating the heavy oil. The induction coil and the outer cylinder form an induction heater.
It enables rapid heating of heavy oil, improves heating efficiency and heat exchange effect, and promotes the exploitation of heavy oil wells.

TECHNICAL FIELD
[0001] The utility model belongs to the auxiliary oil conveying equipment for the heavy oil well of oil field, it is the device for the heavy oil well to heat and reduce viscosity at the well head, specifically a kind of heavy oil well head oil outlet pipeline heating device. BACKGROUND
[0002] When heavy oil extracted from oil field is transported, the heavy oil in pipeline needs to be heated at well head, so that its viscosity is reduced to increase the flowability of crude oil, to ensure that it can be smoothly transported to oil storage station.Currently, the heavy oil in pipeline is heated at well head by installing heating furnace at well head, using natural gas separated from casing in well as heat source or directly using crude oil as fuel to burn in heating furnace to heat heavy oil.Some wells contain little gas, which cannot meet the heating requirement, so only crude oil can be used as fuel, which will cause environment, and artificial full-time period needs to be kept, management is difficult, and heating effect is poor.In order to solve the above problems, some use electric heating method to heat and reduce viscosity of heavy oil, but current electric heating furnace has low heating efficiency, high energy consumption, and unsatisfactory energy saving and emission reduction effect. SUMMARY
[0003] The utility model discloses a kind of heavy oil well head oil outlet pipeline heating devices, overcome the above-mentioned deficiency, improve heating efficiency.
