Abstract
Provided is a graphene heating thermal preservation sleeve for a wellhead of an oil-gas well in an oil field, the sleeve comprises a high-temperature-resistant thermal preservation layer (), a graphene layer (), an electrode layer (), a high-temperature-resistant ceramic layer (), a waterproof anti-static thermal preservation layer () and a housing () tightly attached together in sequence. Two parts of the heating thermal preservation sleeve are buckled together to enclose an oil-gas well wellhead apparatus () needing to be heated. When the electrode layers () at the two ends of the graphene layer () are electrified, under the action of an electric field, heat energy generated by violent friction and impact between carbon atoms of graphene is radiated out by means of far infrared rays with a wavelength in a range of 5-14 micrometers, for heating and thermal preservation of the oil-gas well wellhead apparatus () in an oil field.
