Graphene heater for oil tank of oil field

A graphene heater for an oil tank of an oil field, comprising:

• a cylindrical housing, wherein one end of the housing is closed and is plugged into the oil tank, and an other end of the housing is provided with a flange plate and is fixed on a surface of the oil tank;
• an attachment structure attached to an inner wall of the housing, wherein the attachment structure comprises a first high-temperature-resistant insulating layer, an intermediate layer and a second high-temperature-resistant insulating layer which are attached and connected in sequence;
• the intermediate layer comprises a graphene layer and electrode layers located at two ends of the graphene layer;
• the electrode layers are connected with high-temperature-resistant wires;
• a high-temperature-resistant insulating sheet having a same cross-sectional shape as that of an inner cavity of the housing, wherein the high-temperature-resistant insulating sheet is clung to and covers an entire inner surface of the closed end of the housing;
• a perforated high-temperature-resistant insulating sheet having the same cross-sectional shape as that of the inner cavity of the housing;
• and
• a junction box connected with the flange plate;
• wherein the perforated high-temperature-resistant insulating sheet and the high-temperature-resistant insulating sheet are respectively clung to two end faces of the attachment structure;
• and the end faces are perpendicular to an axis of the housing.
