Abstract
A kind of casing coupling with heat insulating function, including casing coupling, are equipped with internal thread on the madial wall at casing coupling two ends, offer cavity in described sleeve pipe box cupling madial wall, cavity shape in a ring, and heat-barrier material is filled with the cavity；Middle inside described sleeve pipe box cupling is provided with bushing pipe, and aluminium foil layer and gel carpet veneer are sequentially provided between bushing pipe and casing coupling madial wall, and the two ends of bushing pipe are fixed by check nut with the madial wall of casing coupling.The beneficial effects of the utility model are the thermal conductivity factors that heat-barrier material can reduce casing coupling, prevent thermal loss, can play effective thermal insulation function；Because aluminium foil layer and gel carpet veneer are arranged between bushing pipe and casing coupling, it is thus possible to effectively reduce thermal loss when the high conduction of heat, convection current and radiation.
Description
Technical field
The utility model is related to casing coupling technical field, and in particular to a kind of casing coupling with heat insulating function.
Background technology
The pipe that coupling of petroleum casing pipe material is used to manufacture box cupling is called coupling of petroleum casing pipe material.Every mouth well is according to different
Drilling depth and geological condition, will use several layers of sleeve pipes.Sleeve pipe will be using well cementing of cement after going into the well, and it is different from oil pipe, drilling rod,
Cannot reuse, belong to disposable consumable material.
In the prior art, the condition of oil exploitation is：Oil could flow in the case that oil needs certain heat, because
This heat for needing to ensure viscous crude in oil exploitation will not lose too fast so that viscous crude being capable of smooth flow, it is ensured that production is made
Industry is normally carried out.The heat-proof quality of current sleeve pipe is very perfect, and the heat-proof quality of casing coupling can not meet always
Demand, therefore, it is necessary to provide a kind of sleeve pipe with heat-proof quality to meet requirement.
Utility model content
The purpose of this utility model is to provide a kind of casing coupling with heat insulating function, to solve above-mentioned background technology
The problem of middle proposition.
To achieve the above object, the utility model provides following technical scheme：
A kind of casing coupling with heat insulating function, including casing coupling, are equipped with the madial wall at casing coupling two ends
Internal thread, offers cavity in described sleeve pipe box cupling madial wall, cavity shape in a ring, and heat-barrier material is filled with the cavity；
Middle inside described sleeve pipe box cupling is provided with bushing pipe, and aluminium foil layer and gel are sequentially provided between bushing pipe and casing coupling madial wall
Carpet veneer, the two ends of bushing pipe are fixed by check nut with the madial wall of casing coupling.
As further program of the utility model：The heat-barrier material is made up of glass fiber material.
As the utility model further scheme：The bushing pipe is made up of stainless steel material.
As the utility model further scheme：The thickness of the aluminium foil layer and gel carpet veneer is 1mm.
The beneficial effects of the utility model are the thermal conductivity factors that heat-barrier material can reduce casing coupling, prevent heat from damaging
Lose, effective thermal insulation function can be played；Because aluminium foil layer and gel carpet veneer are arranged between bushing pipe and casing coupling, because
And thermal loss when can effectively reduce the high conduction of heat, convection current and radiate.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1- casing couplings, 2- cavitys, 3- heat-barrier materials, 4- bushing pipes, 5- aluminium foil layers, 6- gels carpet veneer, 7- and tight spiral shell
Cap.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Fig. 1 is referred to, in the utility model embodiment, a kind of casing coupling with heat insulating function, including casing coupling
1, internal thread is equipped with the madial wall at the two ends of casing coupling 1, cavity 2, cavity 2 are offered in the madial wall of described sleeve pipe box cupling 1
Shape, is filled with heat-barrier material 3 in a ring in the cavity 2, and heat-barrier material 3 can reduce the thermal conductivity factor of casing coupling 1, prevent
Thermal loss, can play effective thermal insulation function；
Middle inside described sleeve pipe box cupling 1 is provided with bushing pipe 4, is sequentially provided between bushing pipe 4 and the madial wall of casing coupling 1
Aluminium foil layer 5 and gel carpet veneer 6, the two ends of bushing pipe 4 are fixed by check nut 7 with the madial wall of casing coupling 1, due to aluminium foil layer
5 and gel carpet veneer 6 be arranged between bushing pipe 4 and casing coupling 1, it is thus possible to effectively reduce the high conduction of heat, convection current and radiation
When thermal loss.
The heat-barrier material 3 is made up of glass fiber material.
The bushing pipe 4 is made up of stainless steel material.
The thickness of the aluminium foil layer 5 and gel carpet veneer 6 is 1mm.
Operation principle of the present utility model is：Heat-barrier material 3 can reduce the thermal conductivity factor of casing coupling 1, prevent heat
Loss, can play effective thermal insulation function；Because aluminium foil layer 5 and gel carpet veneer 6 are arranged on bushing pipe 4 and casing coupling 1
Between, it is thus possible to effectively reduce thermal loss when the high conduction of heat, convection current and radiation.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, can in other specific forms realize that this practicality is new
Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new
The scope of type limits by appended claims rather than described above, it is intended that the equivalency fallen in claim is contained
All changes in justice and scope are included in the utility model.Any reference in claim should not be considered as limitation
Involved claim.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each implementation method is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that for clarity, those skilled in the art should
Specification an as entirety, the technical scheme in each embodiment can also be formed into those skilled in the art through appropriately combined
May be appreciated other embodiment.
