Title: ELECTRIC-HEATING WAX REMOVAL AND PREVENTION DEVICE WITH NATURAL GAS POWER GENERATION BASED ON SKIN EFFECT AND APPLICATION THEREOF
Abstract:
Provided are an electric-heating wax removal and prevention device with natural gas power generation based on skin effect and an application thereof. The device comprises a natural gas collecting part, a natural gas power generation part, and an electric-heating wax removal and prevention device powered by the natural gas power generation part. The natural gas collecting part is used for collecting and separating natural gas discharged from a shaft (12); and the natural gas power generation part uses the natural gas for power generation. A power source required for electric heating of a steel-armoured cable is from the natural gas power generation part. A gas source required by the natural gas power generation part can be directly obtained from associated gas produced from an oil well. Thus, the associated gas can be used, and the dependence of electric-heating wax removal and prevention technology on a power grid is avoided.
