The utility model relates to a heating and heat preservation belt of an electric heating film, which comprises a heating part and a heat preservation part, wherein the heating part is formed by a high molecular electric heating film and insulation layers arranged at the two sides of the electric heating film. The heat preservation part is formed by tinfoil and heat insulating materials. Furthermore, conductive glues are coated on the inside of the heating and heat preservation belt of the electric heating film so that the heating and heat preservation belt of the electric heating film can be better contacted to an oil storage tank and the oil storage tank can be better conducted heat simultaneously. The heating and heat preservation belt of the electric heating film resolves the problem of heating and heat preservation of high viscosity crude oil of oil fields under the low temperature and is especially suitable for being applied to a thickened oil storage tank with a low ambient temperature and high contents
