Abstract
The utility model discloses an insulating sleeve for a christmas tree of a gas well, which is applied to the heat insulation of the christmas tree of the gas well in an oil field. The insulating sleeve for the christmas tree of the gas well mainly consists of a main body, side arms, a cone and a bottom; the main body is a cylinder with a cross section in a circular ring shape, the upper end of the main body is connected with the cone with a cross section in a circular ring shape; the side arms in a cylinder shape are symmetrically and vertically connected on the main body, and the cross sections of the side arms are also respectively in the shape of a circular shape. The inner chambers of the main body, the side arms and the cone are interconnected. The bottom in a circular ring shape is connected with the lower end of the main body. A sealed chamber is formed between the main body, the side arms, the cone and the bottom. The utility model has the following effects that after the insulating sleeve is mounted on the christmas tree of the gas well, the heat transfer between the inside and the outside of the christmas tree is prevented due to the adoption of a material with a low heat conductivity, dusts are prevented from entering the space between the insulating sleeve and the christmas tree, and therefore, the service life of the christmas tree is prolonged.
Description
Technical field
The utility model relates to the oil field shaft mouth lagging facility, is a kind of muff that is applicable to the gas well christmas tree.
Background technology
The gas field gas well needs christmas tree is incubated, and to reduce the gas well thermal loss, guarantees the gas well safety in production.Two kinds of forms are adopted in existing gas well christmas tree insulation: the one, fill out the incompressible polyurethane elastomer blowing agent in porous crack in adopting, and add epoxy glass laminate protection box.The 2nd, adopt and twine heat-preservation cotton.There is subject matter in these two kinds of methods: 1, must remove during big, the christmas tree maintenance of volume, and need crane gear to cooperate; 2, inconvenience is installed, needs the professional to finish; 3, inflammable, explosion hazard gases delay is easily caused in the incubation chamber inner space, brings potential safety hazard.4, twine the heat-preservation cotton insulation, can not reuse, and harmful, labour intensity is big, safeguards the replacement cost height, and not rainproof.
The utility model content
The purpose of this utility model is: a kind of gas well christmas tree muff is provided, can reduces the gas well thermal loss for the insulation of gas well christmas tree, guarantee the gas well safety in production.Overcome heat-preservation cotton and incubation chamber dismounting inconvenience, need equipment to cooperate and the life cycle weak point, the deficiency that waste and old asbestos pollute environment.
The technical solution adopted in the utility model is: gas well christmas tree muff, mainly form by main body, side arm, cone and the end, and it is characterized in that: main body is a circle ring column shape, the cross section of main body is an annular; Be connected with a cone in the upper end of main body, the cross section of cone is an annular; Symmetry vertically is connected with side arm on main body, and side arm is a circle ring column shape, and the cross section of side arm is an annular; The inner chamber UNICOM of main body, side arm and cone.Be connected with the end in the main body lower end, the end is an annular.Main body, side arm, cone and at the end between an airtight cavity is arranged, the profile of airtight cavity and gas well christmas tree is approximate, and gas well christmas tree muff is fixed on the outside of gas well christmas tree, can play insulation effect.
Described main body, side arm, cone and the end, are divided into extexine, endosexine and intermediate filling layer.Extexine and endosexine adopt that plate is bonding to be become, and between extexine and the endosexine intermediate filling layer are arranged, and intermediate filling layer adopts the alumina silicate fibre needle punched blanket.The thickness at main body, side arm, cone and the end is between 50～200 millimeters.
Manufacturing process: after fleece done top layer skeleton (muff extexine and endosexine) typing, be coated with good with plasticity, that intensity is high is transparent, heat resistance, resin material that oil resistivity is high, after treating the resin material hardened forming, between extexine and endosexine, fill alumina silicate fibre needle punched blanket insulation layer, connection buckle fast is installed in the junction at last.
Installation steps: single christmas tree muff partly is made up of two of symmetry, installs on the christmas tree muff to connect buckle fast, will be incubated retaining ring during installation respectively and be anchored on the christmas tree, and locked then quick connection buckle is finished installation.Also adopting quick Connection Card to link between each monomer connects.
The beneficial effects of the utility model: the utility model gas well christmas tree muff, gas well christmas tree muff is installed on the christmas tree, owing to adopt the low material of coefficient of thermal conductivity, effectively stop the inside and outside heat of christmas tree to be transmitted, effectively stop sand and dust to enter between christmas tree and the muff, prolong christmas tree application life, kept the christmas tree cleaning.Product is for dividing body structure, and every weight is no more than 25kg simultaneously, does not need hanging device during dismounting, and piece adopts the quick buckle (or bolt) that is connected to connect with piece, can arbitrarily dismantle any heat insulating block, has made things convenient for the needs of on-the-spot checking maintenance dismounting.The innocuousness of its material and the once permanent use of input have been protected environment and have been avoided health effects has been reduced cost, reclaim conveniently.

The specific embodiment
Embodiment 1: with a gas well christmas tree muff is example, and the utility model is described in further detail.
Consult Fig. 1.The utility model gas well christmas tree muff mainly is made up of main body 1, side arm 2, cone 3 and the end 4.Main body 1 is a circle ring column shape, and the cross section of main body 1 is an annular, 260 millimeters of main body 1 internal diameters, 470 millimeters of external diameters, 1500 millimeters of height; Be connected with a cone 3 in the upper end of main body 1, the cross section of cone 3 is an annular; 250 millimeters of cone 3 height.Bilateral symmetry in main body 1 vertically is connected with a side arm 2 respectively, and side arm 2 is a circle ring column shape, and the cross section of side arm 2 is an annular, 70 millimeters of the internal diameters of side arm 2,200 millimeters of external diameters, 1100 millimeters of length.The inner chamber UNICOM of main body 1, side arm 2 and cone 3.At the bottom of main body 1 lower end is connected with one 4, the end 4 is an annular, 50 millimeters of the thickness at the end 4., there is centre bore at the end 4, and the diameter of centre bore is 150 millimeters.
