Abstract
A thermal insulating arrangement for christmas tree relates to the thermal insulating arrangement for oilfield christmas tree, wherein the shell thermal insulating arrangement of a christmas tree consists of a hollow PVC plastic steel thermal insulating layer 2 and froth 3; the froth 3 is filled in the hollow PVC plastic steel thermal insulating layer 2. The thermal insulating arrangement can make oil well head pull-in pipelines remove muffle furnace heating, effectively saves natural gas energy, makes the back pressure of oil wells reduced, and improves crude oil recovery factor. The thermal insulating arrangement for christmas tree is high in sealing performance, little in heat loss, thermal insulating, flame retardant, high in anticorrosive performance, easy to be cleaned, environment protecting, energy saving, convenient to be installed and dismantled, low in cost and improved in work efficiency.
Description
The utility model relates to the attemperator of the attemperator of oil well mouth production tree, particularly a kind of production tree.
At present in field produces; the insulation of production wellhead production tree, the attemperator of anticorrosion process adopt glass wool directly to be incubated always; or the internal layer of insulation layer adopts felt, the necessary mopping of outer field glass wool cloth; but all effectively be incubated; perishable, inflammable; and the wiping in winter is incubated outer field greasy dirt suffering, wastes energy in field produces, can not well protect environment and increases work efficiency.
In order to overcome above-mentioned difficulty, the purpose of this utility model provides the attemperator of a kind of production tree, the attemperator of a kind of production tree can be incubated highly, be difficult for that burn into and good flame retardation effect, good seal performance, thermal loss are little, the greasy dirt poor adhesive force, to be easy to scouring, safety and environmental protection, installation simple, be convenient to the shaft mouth operation of producing well, increase work efficiency.
To achieve these goals, the main technical schemes of the attemperator of a kind of production tree of the utility model is, insulation layer in the outside of well head production tree adopts hollow PVC plastic-steel, add in hollow PVC plastic-steel the inside again and fill foaming, realized high heat insulation effect like this, make little that the loss of heat becomes, and improved antiseptic effect, fire-retardant, easy cleaning.
The attemperator of a kind of production tree of the utility model is that the shell production tree adds insulation layer, this insulation layer can make the well mouth of oil well pipeline that enters the station remove blind roaster heating, effectively save natural gas energy resource, Oil Well Back Pressure is reduced, improve oil recovery factor, this production tree attemperator sealing performance height, heat-insulating and fire-proof, the antiseptic property height, easily scouring, environmental protection and energy saving, easy installation and removal are increased work efficiency.
Fig. 1 is the front view of the attemperator of a kind of production tree.
Fig. 2 is the sectional view of the attemperator of a kind of production tree.
Describe an embodiment (as shown in Figure 1 and Figure 2) below in conjunction with accompanying drawing: the shell production tree adds attemperator 1, the insulation layer 2 of this attemperator 1 is the hollow PVC plastic-steel that adopts mould to make, add in hollow PVC the inside again and fill foaming 3, foamable 3 then, make the inner separation layer that forms of hollow PVC plastic-steel, increase insulation intensity; This attemperator can be decided according to the size of production tree, the high end, utilized the mould one-shot forming, realized high-seal; This insulation layer is to be fastened on the shell of production tree with screw, prevents to come off.
Claims (2)
1, the attemperator of a kind of production tree is made up of insulation layer (2) and foaming (3), and it is characterized in that: insulation layer (2) is hollow, is filled with foaming (3) in hollow insulation layer (2) the inside.
2, the attemperator of a kind of production tree according to claim 1 is characterized in that: hollow insulation layer (2) is to be made by hollow PVC plastic-steel.
