Thermal insulation heating blanket for wellhead oil extraction equipment

Abstract

The invention relates to a thermal insulation heating blanket for wellhead oil extraction equipment, is particularly applicable to a low-voltage thermal insulation heating device for well-control equipment, and belongs to the technical field of heat conduction. The thermal insulation heating blanket comprises an electric heating tape and a thermal insulation fireproof coverlet, wherein the electric heating tape is composed of an electric heating wire, a fiberglass layer and a silicone layer; the thermal insulation fireproof coverlet is composed of an outer aluminum foil layer, an inner fireproof cloth layer and a middle thermal insulation cotton layer; and the electric heating tape is disposed in the thermal insulation cotton layer in the middle of the thermal insulation fireproof coverlet. The electric heating tape disclosed by the invention is available for independent use under special circumstances. The silicone layer as the outer layer of the electric heating tape enhances insulativity of the electric heating wire and improves the flexibility and strength, and overcomes the defect that a traditional surface made of metal or ceramic is difficult to bend. Moreover, the thermal insulation performance of the electric heating tape is also improved. The thermal insulation heating blanket has the advantages of fireproof, electric leakage prevention, short circuit prevention, high heat efficiency and the like.

Description

technical field [0001] The invention relates to a thermal insulation heating blanket for wellhead oil production equipment, and is particularly suitable for a low-voltage thermal insulation heating device for well control equipment. It belongs to the technical field of heat conduction. Background technique [0002] At present, the well control equipment thermal insulation devices used in various drilling, sidetracking, and major workover construction sites all use electric heating cables with a voltage of 220V for thermal insulation. Low temperature and short service life. At the same time, the outer material of some electric heating belts is made of metal or ceramics, so it is not easy to bend, so it is not easy to wrap branch-shaped wellhead equipment. Above-mentioned these defectives have become a great potential safety hazard of underground operation construction in winter. For this reason, we specially developed a thermal insulation heating blanket for wellhead oil pr...
