Abstract
The utility model provides a thermal insulator at well openings, which belongs to a thermal insulator at oil extraction well openings of oil fields. The utility model is provided with a casing and the other casing which are hinged together, wherein the internal parts of the two casings are respectively provided with a thermal insulating material body and the middle parts of the two thermal insulating material bodies are surrounded into arranged holes of the well openings. The thermal insulator at well openings has the advantages of convenient installation and construction and good thermal insulating effects; thermal insulating property is apparently higher than the traditional thermal insulating form; the utility model can be repeatedly used, and the waste can be avoided. Simultaneously, the utility model can also prevent the well opening device from being subjected to corrosion because of thermal insulation.
Description
Technical field
The utility model provides a kind of attemperator, especially a kind of attemperator of oil well mouth.
Background technology
Oil well must be incubated wellhead assembly after entering production in winter.In the past adopt the rock wools wrapping more, stick with paste with mud, methods such as glass wool cloth are twined in the outside, and heat insulation effect is not ideal enough, construct loaded down with trivial details, labour intensity is high, spoilage is higher, insulation often needs repeatedly to repeat in season to construct, and causes waste.In addition, also cause the wellhead assembly corrosion easily.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of well head attemperator, to improve the convenience of heat insulation effect and installation.
The utility model is achieved in that the well head attemperator, and it has hinged shell and another shell, and the heat insulating material body is arranged respectively in two shells, and two heat insulating material bodies middle part surrounds the wellhead assembly hole.
Adopt the well head attemperator of said structure, installation is convenient, high insulating effect, and heat-insulating property is incubated form apparently higher than tradition, and can reuse, and has avoided waste.Simultaneously, prevented that also wellhead assembly from being corroded because of insulation.
Description of drawings
Fig. 1 is the front view of the utility model structure.
Fig. 2 is the top plan view of Fig. 1.
Among the figure, 1-shell, 2-hinge, 3-another shell, 4-heat insulating material body, 5-wellhead assembly hole, 6-set bolt.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing illustrates concrete structure of the present utility model and installation and application.
As shown in drawings, the well head attemperator of the utility model, it has by hinged shell (1) and another shell (3), and heat insulating material body (4) is arranged respectively in two shells, and two heat insulating material bodies middle part surrounds wellhead assembly hole (5).
Described shell (1) and another shell (3) are hinged by hinge (2).Hinge two blades are separately fixed on two shells, are installed together by hinge in the middle of two blades.Certainly, can also adopt other articulated manner.
Described shell (1), another shell (3) are that material is made with glass fiber reinforced plastic, and described heat insulating material body (4) is that material is made with the rock wool.
In two shells, be packed into heat insulating material such as rock wool respectively and constitute the heat insulating material body.The profile of wellhead assembly is generally tubular, so wellhead assembly hole (5) are generally circular hole.Obviously, the wellhead assembly hole also can be other suitable shapes.
This well head attemperator, elder generation carries out prefabricated according to the different model of well head, when needing insulation, two shells are opened along hinge, after being buckled in this attemperator on the wellhead assembly, can fix getting final product, also can adopt the bonding additive method that waits to fix by set bolt (6).Simple installation can be incubated season at the next one and reuse, and has avoided waste, has reduced cost.Because this attemperator adopts the dry type heat preserving mode, has avoided the well head corrosion.
Claims (3)
1, the well head attemperator is characterized in that, it has hinged shell (1) and another shell (3), and heat insulating material body (4) is arranged respectively in two shells, and two heat insulating material bodies middle part surrounds wellhead assembly hole (5).
2, well head attemperator as claimed in claim 1 is characterized in that, described shell (1) and another shell (3) are hinged by hinge (2).
3, well head attemperator as claimed in claim 1 or 2 is characterized in that, described shell (1), another shell (3) are that material is made with glass fiber reinforced plastic, and described heat insulating material body (4) is that material is made with the rock wool.
