Abstract
The utility model discloses a kind of thermal compensation petroleum pipeline deferent box cupling structure, including steel conduit, overcoat, pipe box cupling, it is characterized in that, steel conduit two ends respectively add a pipe box cupling, steel conduit inwall is provided with internal lining pipe, overcoat is socketed with the outside of pipe box cupling, pipe box cupling outer surface has with overcoat inner surface setting is connected with turbine meter on meltable solid or Electric radiant Heating Film, pipe box cupling.With simple in construction, production cost is low, the characteristics of service life is long.
Description
Technical field
The utility model belongs to petroleum pipeline technical field, more particularly to a kind of thermal compensation petroleum pipeline deferent box cupling knot
Structure.
Background technology
At present, surrounding city and part, which have, alters the oil well for putting earth's surface risk and needs to carry out capping operation, and oil field on oil gas
The old well in initial stage of development part is without layer sleeve pipe, seriously corroded in bad repair with age, and oil well casing is main in structure of oil well
Part, the sleeve structure of domestic and international oil well connects one for a two ends with externally threaded tube column and its one end
Screwed box cupling above and below inside, each sleeve pipe can be interconnected.After oil well completion, outside casing string by cement with
Stratum is fixed, and when oily well temperature is improved, sleeve pipe extends because of thermal expansion factor, due to well cementing of cement effect, sleeve pipe elongation
Part is nowhere stretched, therefore casing string can be caused to bend or deform, or even cement sheath in oil well is squeezed into bad, cause stratum to gang up,
Damage, particularly thermal production well, oil well casing deformed damaged rate is up to more than 80%.Although at present technically just like prestressing force skill
Art, thermal compensation expansion bend, using the method such as high-strength thick sleeve pipe and preheating well cementation, above mentioned problem still can not obtain fundamentally
To solution.
Utility model content
The utility model is intended to overcome the defect of prior art there is provided a kind of thermal compensation petroleum pipeline deferent box cupling structure, has
Have simple in construction, production cost is low, the characteristics of service life is long.
In order to solve the above-mentioned technical problem, the utility model provides following technical scheme：
A kind of thermal compensation petroleum pipeline deferent box cupling structure, including steel conduit 2, overcoat 3, pipe box cupling, it is characterised in that steel pipe
The two ends of road 2 respectively add a pipe box cupling 4, and the inwall of steel conduit 2 is provided with the outside of internal lining pipe 1, pipe box cupling and is socketed with overcoat 3, and pipe connects
Bind round 4 outer surfaces and the inner surface setting of overcoat 3 and have and be connected with turbine meter 6 on meltable solid 5 or Electric radiant Heating Film, pipe box cupling 4.
Further, the meltable solid is loop configuration, is solid state when environment temperature is less than certain value, works as ring
It is liquid condition that border temperature is melted when being higher than certain value.
Further, the overcoat is tubular-shaped structures, and overcoat is stainless steel insulated sheath.
Compared with prior art, the utility model has following beneficial effect：
The utility model is simple in construction, and production cost is low, and service life is long；By being socketed overcoat, pipe in pipe box cupling appearance
Meltable solid is installed between box cupling and overcoat or Electric radiant Heating Film strengthens the heat-insulating property of petroleum pipeline, pipe box cupling in use, pipe
Box cupling is connected with turbine meter and the flow in pipeline can be measured in real time.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model thermal compensation petroleum pipeline deferent box cupling structure.
Embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
As shown in figure 1, a kind of thermal compensation petroleum pipeline deferent box cupling structure, including steel conduit 2, overcoat 3, pipe box cupling, it is special
Levy and be, the two ends of steel conduit 2 respectively add a pipe box cupling 4, the inwall of steel conduit 2 is provided with the outside of internal lining pipe 1, pipe box cupling and is socketed with
Overcoat 3, the overcoat is tubular-shaped structures, and overcoat is stainless steel insulated sheath.Pipe box cupling includes a upper box cupling, a locking
Nut, multiple sealing rings and a lower box cupling being assembled together in order.The outer surface of pipe box cupling 4 has with the inner surface setting of overcoat 3
Turbine meter 6 is connected with meltable solid 5 or Electric radiant Heating Film, pipe box cupling 4.The meltable solid is loop configuration,
Environment temperature is solid state when being less than certain value, and it is liquid condition to melt when environment temperature is higher than certain value.Pipe box cupling bag
Include a upper box cupling, locking nut, multiple sealing rings and a lower box cupling being assembled together in order.
Explanation embodiment of the present utility model is the foregoing is only, the utility model is not limited to, for ability
It is all within spirit of the present utility model and principle for the technical staff in domain, any modification, equivalent substitution and improvements made
Deng should be included within protection domain of the present utility model.
