Abstract
The invention discloses a composite nanometer aerogel anti-corrosion insulation oil tube, which aims to provide the composite nanometer aerogel anti-corrosion insulation oil tube with a four-layer composite system and solve the technical problems that wax precipitation occurs on the wall of a tube, crude oil hangs on the wall, the outlet oil temperature of the crude oil is increased, the inner part of the oil tube is corroded and the like in the process of crude oil extraction. The composite nanometer aerogel anti-corrosion insulation oil tube comprises an inner anti-corrosion coating, a second layer of oil tube metallic matrix, a third insulation layer and an outer protective layer, wherein a nanometer SiO2 aerogel blanket is adopted in the third insulation layer, and the outer protective layer is coated by crosslinking high density polyethylene (XHDPE). According to the composite nanometer aerogel anti-corrosion insulation oil tube, the strata heat is fully utilized to satisfy the process requirement of the crude oil extraction, the heat fluid circulation and an electric heating system of the prior art are replaced, and a large amount of fuel, electric energy and personal expenses are saved.
Description
Technical field
The present invention relates to a kind of oil pipe, relate in particular to a kind of composite Nano aerogel corrosion-resistant thermal insulation oil pipe.
Background technique
The kind of crude oil is a lot, crude oil in the process of exploitation, up along with Produced Liquid, its temperature can reduce gradually, tube inner wall wax deposition or viscous crude wall cling phenomenon can occur, causes the pumping swab to be transferred in oil pipe being hampered or carries and meet card.Domestic recovery method adopts hot fluid circulation heating technology and electric-heating technology usually at present, but the required energy consumption of this type of mode of production is high, and management difficulty is large.Present oil pipe does not have heat insulation effect.
Summary of the invention
The objective of the invention is for solving the problems such as the wall wax deposition that occurs in the oil extraction process, crude oil wall built-up, and a kind of energy-saving composite Nano aerogel corrosion-resistant thermal insulation oil pipe is provided.
The technological scheme that adopts is:
A kind of composite Nano aerogel corrosion-resistant thermal insulation oil pipe comprises the oil pipe metallic matrix, and the outside of oil pipe metallic matrix is coated with from inside to outside successively by nanometer SiO
2The thermal insulation layer that aerogel blanket is made and the external protection of being made by crosslinked high density polyethylene; thermal insulation layer is shorter than protective layer at oil pipe metallic matrix two ends; the two ends of protective layer are by the gluing direct and oil pipe metallic matrix bonding of jacket, and the inwall of oil pipe metallic matrix scribbles anticorrosive coat in two component hot settings.
Than the short 300mm of oil pipe, than the short 200mm of oil pipe, two ends are than the short 200mm of oil pipe metallic matrix at the oil pipe two ends for protective layer at the oil pipe two ends for above-mentioned thermal insulation layer.
The thickness of above-mentioned thermal insulation layer is 5-8mm, and the thickness of external protection is 2-3mm.The thickness of interior anticorrosive coat is 200 ± 20 microns.
Above-mentioned protective layer at oil pipe metallic matrix two ends respectively than the long 100mm in thermal insulation layer two ends.
The present invention takes full advantage of the technological requirement that the stratum heat satisfies oil extraction, has banned hot fluid circulation, electric heating system in the former technique, has saved a large amount of fuel, electric energy and personal expenditures.
