Because the length of oil pipe is typically in several kms, often occur in oil well operation because of the oil that is too fast and triggering that radiates
Product retrogradation caking phenomenon, cause oil pipe blocking, cracking is even broken, and causes very big potential safety hazard.At the same time, due to oil product
Highly corrosive and the wet environment of underground, oil pipe are easy to the damage that is corroded, and service life is extremely limited.
Oil pipe use high cost superior alloy steel material manufacture, it is impossible to discard easily, and in underground as deep as several kms
Oil pipe carry out Corrosion Repair or degrease and dredge blockage is nor an easy thing.An even if annual production 200
Ten thousand tons of small-sized oil field, the corrosion and blocking of oil pipe are avoided if do not adopted an effective measure, the annual oil for needing to repair or change
Pipe just up to 170,000.This also will be an astronomical figure in terms of 700 yuan of the maintenance cost of every.And use traditional insulation or
Water-proof and anti-corrosive material generally requires enough thickness competence exertion effects, and this is limited by oil well casing diameter.And
Traditional material needs complicated bonding or spraying coating process, is also restricted its application.Therefore traditional material can not be to oil pipe
Play effective insulation and antiseptic effect.
The content of the invention
Patent of the present invention is directed to above-mentioned the deficiencies in the prior art, there is provided a kind of high-performance insulation with corrosion-proof lining is adopted
Oil pipe, can effectively solve the problems, such as the insulation of oil pipe and corrosion.
Patent of the present invention is achieved through the following technical solutions, and patent of the present invention includes flow string, high-performance is incubated

Silicon glass-fiber-fabric, thin metal sealing protection sleeve pipe are wrapped on the outside wall surface of flow string, silica glass-fiber-fabric and high property successively
The equal length of energy insulation material, thin metal sealing protection sleeve pipe length are slightly larger than the length of high-performance insulation material, sealing-plug
The both ends of flow string are arranged in, corrosion-proof lining is arranged in the internal face of flow string, and high-performance insulation material is nanoporous aerogel hair
Felt.
Further, in patent of the present invention, corrosion-proof lining is sleeve structure, and the thickness of corrosion-proof lining includes but is not limited to
1mm, the material of corrosion-proof lining include but is not limited to 304,314,316,825 stainless steel materials.
Further, in patent of the present invention, between corrosion-proof lining and flow string by way of HTHP or cold pressing
Link together, the material of sealing-plug is high temperature resistant and organic solvent material anti-to a certain degree.
Further, in patent of the present invention, the thickness of high-performance insulation material include but is not limited to 0.01 meter and
0.005 meter；The thickness of silica glass-fiber-fabric includes but is not limited to 0.0001 meter, 0.0002 meter and 0.0003 meter；Thin metal is close
The material of envelope protection sleeve pipe includes but is not limited to stainless steel tube, stainless steel tube and other converted steel pipes, species include seamless pipe and
Seamed pipe；The thickness of thin metal sealing protection sleeve pipe includes but is not limited to 0.001 meter, 0.002 meter and 0.003 meter；The sealing
Plug includes but is not limited to teflon seal plug and thermostable fluorine elastomeric material sealing-plug, and the thickness of the sealing-plug is 0.01
Rice.
The beneficial effect of patent of the present invention is：Patent design of the present invention is reasonable, simple in construction, and oil pipe heat preservation technology uses more
Kind means, heat insulation effect is fabulous, while has anti-corrosion function again；Using corrosion-proof lining steel-tube construction, greatly improve steel pipe and adopting
Decay resistance in oil, oil transportation, oil refining and commercial processes, surface is smooth, and fluid resistance is small, remains steel pipe mechanical again
Intensity is high, improves the service life of steel pipe and improves safety production efficiency.
