Description
Technical field
The present invention relates to insulated tubing, specifically a kind of aerogel heat-proof oil pipe.
Background technology
Insulated tubing is the heat-insulated main tool of Field In The Steam Injection Wells, is the key factor for influenceing steam injection quality.It is domestic it is existing every
Deep fat pipe is that heat-insulated and insulation effect is reached as heat insulation loop cavity using aluminium foil, glass cross between inner and outer pipes, depending on
Thermal conductivity factor is less than 0.02W/ (m. DEG C).But as the generally development that steam drives technique is increasingly urgent with energy saving and efficiency increasing situation,
Requirement higher is proposed to instlated tubular performance, service life.
Aeroge is a kind of heat insulating material, with thermal conductivity factor low (0.013~0.025w/ (m DEG C)), it is lightweight,
Water resistance is good, long service life the features such as, in the industrial pipelines such as defence and military, aircraft, metallurgy, chemical industry and electric ice
Good application effect is achieved on the insulation of case etc., but it is simultaneously few in the application of petroleum industry, at present only on ground
Preferable application effect is achieved in the insulation of facial canal line, application is there is no in terms of steam injection thermally insulating the borehole.Therefore airsetting glue material
Material is applied in insulated tubing, and service life can be improved while heat-proof quality is ensured, expands the application field of instlated tubular,
Heavy crude heat extraction economic benefit and social benefit are improved, while the blank in this field can be filled up.
The content of the invention
It is an object of the invention to provide a kind of aerogel heat-proof oil pipe, it is by the use of aerogel composite as heat-insulated annular space
Chamber, and heat insulation loop cavity is carried out into application of vacuum or inert gas is recharged, improve its heat-proof quality.The insulated tubing has
Thermal insulation level is high, long service life the characteristics of.
In order to reach above-mentioned purpose, present invention employs following technical scheme, a kind of aerogel heat-proof oil pipe, including inner tube
And outer tube, the outer tube sleeve forms closed heat insulation loop cavity, the heat insulation loop outside inner tube and between inner and outer tubes
Filling with insulation material in cavity.
The heat-barrier material uses aeroge.
At least one centering ring is set in the heat insulation loop cavity.
Said inner tube two ends are in horn-like.
Said inner tube left end is welded on the left end inwall of outer tube, and then inner tube right-hand member is by welding after design expansion rate heating elongation
In the right-hand member of outer tube.
The heat insulation loop cavity inside vacuumizes or recharges inert gas.
Compared to prior art, the invention has the advantages that：
Outer wall of inner tube parcel of the invention is welded by the heat insulation loop cavity of aerogel composite after one end enlarging of inner tube
The inside of outer tube is connected on, the other end of inner tube is by the other end that outer tube is welded on after the swollen rate heating elongation of design；And it is right
The heat insulation loop cavity of insulated tubing carries out high temperature and vacuumizes or recharge inert gas.
The present invention is as a result of thermal conductivity factor is low, the aeroge insulation material of high temperature resistant and long service life, the gas of development
Gel heat-insulation pipe apparent heat conductivity≤0.01W/ (m. DEG C), heatproof reaches 400 DEG C；Low-carbon environment-friendly, long service life, with height
Vacuum heat insulation tube is compared, service life extension more than 50%；Steam injection quality is ensure that, the application timeliness of instlated tubular is improve,
Thermal recovery cost is reduced, the economic development benefit of viscous crude is improve.
Brief description of the drawings
Fig. 1 is a kind of structural representation of aerogel heat-proof oil pipe of the invention.
In figure：Box cupling 1, inner tube 2, centering ring 3, heat insulation loop cavity 4, outer tube 5.
Specific embodiment
Detailed description for the present invention and technology contents, coordinate brief description of the drawings as follows, but accompanying drawing only provides and refers to and say
It is bright to be used, not for being any limitation as to the present invention.
According to Fig. 1, a kind of aerogel heat-proof oil pipe, including inner tube 2 and outer tube 5, the outer tube sleeve outside inner tube simultaneously
And closed heat insulation loop cavity 4, filling with insulation material in the heat insulation loop cavity are formed between inner and outer tubes.The heat-insulated material
Material uses aeroge.At least one centering ring 3 is set in the heat insulation loop cavity.Said inner tube two ends are in horn-like.It is described
Inner tube left end is welded on the left end inwall of outer tube, and then inner tube right-hand member is welded on outer tube after being extended by design expansion rate heating
Right-hand member.
Insulated tubing body is connected by box cupling 1 and an other insulated tubing.Pier horn mouth is heated at the two ends of said inner tube 2,
One end is welded on the inside of outer tube 5, and inner tube 2 is interior by the other end that outer tube 5 is welded on after design expansion rate heating elongation
The annular chamber formed between pipe 2 and outer tube 5 is have centering ring 3 to carry out body in heat insulation loop cavity 4, heat insulation loop cavity 4 to consolidate
It is fixed.Heat insulation loop cavity 4 fills aerogel composite, then vacuumizes or recharge inert gas, extends making for insulated tubing
Use the life-span.Before inner tube 2 and outer tube 5 are welded, inner and outer pipe will carry out heating degasification, and suction hydrogen is added in pipe
Agent and getter, are finally vacuumized or are recharged Inert gas welding and blocked up.
Presently preferred embodiments of the present invention is the foregoing is only, is not used to limit the scope of the claims of the invention, other are with this hair
The equivalence changes of bright patent spirit, all should all belong to the scope of the claims of the invention.
