Abstract
The utility model provides an aerogel heat insulation oil pipe, including inner tube and outer tube, thermal insulation material packs and form inclosed heat insulating ring cavity between inner tube and the outer tube in outside of tubes portion including the outer pipe box in this heat insulating ring cavity. Thermal insulation material adopts the aerogel. It rights the ring to set up at least one in the heat insulating ring cavity. The inner tube both ends are the loudspeaker form. The inner tube left end welds the left end inner wall at the outer tube, then the inner tube right -hand member is according to the design expansion rate with the right -hand member of welding after the thermal stretching at the outer tube. The inside evacuation of heat insulating ring cavity or return and fill inert gas. The utility model discloses utilize aerogel combined material as the heat insulating ring cavity to carry out the heat insulating ring cavity vacuum treatment or return and fill inert gas, improve its heat -proof quality. This heat insulation oil pipe has thermal -insulated grade height, long service life's characteristics.
Description
Technical field
The utility model relates to insulated tubing, especially a kind of aerogel heat-proof oil pipe.
Background technology
Insulated tubing is the heat insulation main tool of Field In The Steam Injection Wells, is the key factor that affects steam injection quality. Domestic existing everyDeep fat pipe is between inner and outer pipes, to use aluminium foil, glass cross to reach effect heat insulation and insulation as heat insulation loop cavity, depending onThermal conductivity factor is less than 0.02W/ (m. DEG C). But along with steam flooding technique generally carry out day by day urgent with energy saving and efficiency increasing situation,To having higher requirement in instlated tubular performance, service life.
Aeroge is a kind of heat insulating material, have thermal conductivity factor low (0.013～0.025w/ (m DEG C)), lightweight,The features such as water resistance is good, long service life, at industrial pipeline and electric ice such as defence and military, aircraft, metallurgy, chemical industryOn the insulation of case etc., obtain good effect, but also few in the application of petroleum industry, at present only on groundIn the insulation of facial canal line, obtain good effect, aspect steam injection thermally insulating the borehole, there is no application. Therefore aeroge materialMaterial is applied in insulated tubing, in guaranteeing heat-proof quality, can improve service life, expands the application of instlated tubular,Improve heavy crude heat extraction economic benefit and social benefit, can fill up the blank in this field simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of aerogel heat-proof oil pipe, and it utilizes aerogel composite as heat insulation loopCavity, and heat insulation loop cavity is carried out to application of vacuum or recharges inert gas, its heat-proof quality improved. This insulated tubing toolHave that thermal insulation level is high, the feature of long service life.
The purpose of this utility model can adopt following technical measures to realize:
This aerogel heat-proof oil pipe comprises inner and outer tubes, and described outer tube sleeve is shape between inner tube outside and inner and outer tubesBecome airtight heat insulation loop cavity, filling with insulation material in this heat insulation loop cavity.
The purpose of this utility model also can adopt following technical measures to realize:
Described heat-barrier material adopts aeroge.
In described heat insulation loop cavity, at least one centering ring is set.
Described inner tube two ends are horn-like.
Described inner tube left end is welded on the left end inwall of outer tube, and then inner tube right-hand member welds after adding thermal stretching by design expansion rateAt the right-hand member of outer tube.
Described heat insulation loop cavity inside vacuumizes or recharges inert gas.
The utility model compared with prior art has following beneficial effect:
Outer wall of inner tube of the present utility model wraps up the heat insulation loop cavity being formed by aerogel composite, one end enlarging of inner tubeAfter be welded on the inside of outer tube, the other end of inner tube adds the other end that is welded on outer tube inside after thermal stretching by the swollen rate of design;And the heat insulation loop cavity of insulated tubing is carried out to high temperature vacuumize or recharge inert gas.
The utility model is owing to having adopted the aeroge insulation material of low, the high temperature resistant and long service life of thermal conductivity factor, developmentAerogel heat-proof pipe apparent heat conductivity≤0.01W/ (m. DEG C), heatproof reaches 400 DEG C; Low-carbon environment-friendly, long service life,Compared with high vacuum insulation pipe, extend service life more than 50%; Guarantee steam injection quality, while having improved the application of instlated tubularEffect, has reduced thermal recovery cost, has improved the economic development benefit of viscous crude.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
In figure: 1-box cupling, 2-inner tube, 3-centering ring, 4-heat insulation loop cavity, 5-outer tube.
Detailed description of the invention
Relevant detailed description of the present utility model and technology contents, coordinate brief description of the drawings as follows, but accompanying drawing only provides referenceWith the use of explanation, be not used for the utility model to be limited.
According to Fig. 1, a kind of aerogel heat-proof oil pipe, comprises inner tube 2 and outer tube 5, and described outer tube sleeve in inner tube outside alsoAnd between inner and outer tubes, form airtight heat insulation loop cavity 4, filling with insulation material in this heat insulation loop cavity. Described heat insulation materialMaterial adopts aeroge. At least one centering ring 3 is set in described heat insulation loop cavity. Described inner tube two ends are horn-like. DescribedInner tube left end is welded on the left end inwall of outer tube, and then inner tube right-hand member adds and is welded on outer tube after thermal stretching by design expansion rateRight-hand member.
Insulated tubing body is connected with an other insulated tubing by box cupling 1. Described inner tube 2 two ends heating pier horn mouths,One end is welded on the inside of outer tube 5, and inner tube 2 adds by design expansion rate the other end that is welded on outer tube 5 after thermal stretching, inThe annular chamber forming between pipe 2 and outer tube 5 is heat insulation loop cavity 4, has centering ring 3 to carry out body admittedly in heat insulation loop cavity 4Fixed. Heat insulation loop cavity 4 is filled aerogel composite, then vacuumizes or recharge inert gas, the making of prolong insulation oil pipeUse the life-span. Before inner tube 2 and outer tube 5 are welded, inner and outer pipe will carry out bake out, and in pipe, adds suction hydrogenAgent and getter, finally vacuumize or recharge Inert gas welding stifled.
The foregoing is only preferred embodiment of the present utility model, non-in order to limit the scope of the claims of the present utility model, otherUse the equivalence of patent spirit of the present utility model to change, all should all belong to the scope of the claims of the present utility model.
