Description
Technical field
It is specifically a kind of using graphite as the compound of matrix the present invention relates to the machining manufacture of high-temperature sealing material
High-temperature sealing material machining manufacture.
Background technology
When exploiting deep-layer heavy crude, steam injecting temperature improves, and production temperature will also raise, generally 350 DEG C -400 DEG C, therefore
The heat resistance of downhole tool is required to improve.Downhole tool sealing material is generally using nitrile rubber, hydrogenated butyronitrile rubber at present
Glue, fluorubber etc., although this kind of rubber meets seal request, its heat resistance is poor, usually exists with good elasticity
Between 100 DEG C -240 DEG C.Conventional rubber materials heat resistance cannot meet the requirement of thick oil thermal extraction exploitation via steam injection.This
Outside, it is graphite to commonly use industrial heat-resisting material, it is mainly used for high-temperature pipe elbow junction, is resistant to more than 600 DEG C high temperature, but
The static seal of 2mm can only be no more than as seal clearance.Since its is frangible, elasticity it is small the characteristics of, though with good high temperature resistant
Performance, can not be used for the big annular space deformation of thick oil thermal extraction downhole tool.Therefore it is badly in need of invention one kind with graphite high temperature resistant material
Matter is the combined high temperature sealing material processing method of matrix, can process the high temperature sealing material of suitable thickened oil recovery.
In the prior art, graphite paper is high-carbon scale graphite is chemically treated that high-temperature expansion rolling forms.It is manufacture
The basic material of various graphite seals.Be widely used in the industries such as electric power, oil, chemical industry, instrument, machinery, diamond machine,
Pipe, pump, the dynamic sealing of valve and static seal, are the preferable novel seal materials for substituting the conventional seals such as rubber, fluoroplastics, asbestos
Material.
In the prior art, the material similar with graphite paper also has graphite rope, graphite line etc..
Fibrous material includes inorfil, and inorfil includes asbestos, glass fibre.It is commonly used to make the asbestos being electrically insulated
It is chrysotile, main chemical compositions are the positive britesorb (3MgO2SiO22H2O) containing the crystallization water.When temperature is up to 450
At~700 DEG C, chrysotile will lose water of constitution and become powder.Asbestos fibre in electrician has long fibre (by adding by hand
Work forms) and staple fiber (by machine select and obtain) divide, their common feature is that have very high heat resistance, but dielectric properties compared with
Difference, is typically used as heat safe low voltage motor, electrical apparatus insulation, sealing and gasket material.
The content of the invention
It is an object of the invention to provide a kind of combined high temperature sealing material machining manufacture using graphite as matrix, make
The resistance to elevated temperatures of sealing material greatly improves, and meets heavy oil wells steam injection and production requirement.
In order to achieve the above objectives, present invention employs following technical solution, a kind of combined high temperature using graphite as matrix
Sealing material machining manufacture, comprises the following steps：
Graphite bar, fibrous material, B alloy wire are got out first；
B alloy wire is added in graphite bar and fibrous material, addition manner there are two kinds, and one is wrapped in for 3-5 root B alloy wires
Graphite bar surface and fibrous material surface；Secondly B alloy wire 3-5 roots are wrapped in inside graphite bar and inside fibrous material；
The graphite bar of B alloy wire or graphite bar, the fibrous material of the single B alloy wire of parcel are wound, according to parts by weight 18：1
Proportioning, is knitted to form soft graphite sill, i.e. graphite line on braiding machine.
B alloy wire winds the step of graphite bar and is, B alloy wire and graphite bar by braiding packing machine through 8 ingots, 18 ingots, 24 ingots into
Row cross cap compiles the graphite-based material to form rope form, i.e. graphite rope；The graphite rope of formation is filled in columnar mould, in pressure
For under 60 tons, room temperature is suppressed to form molding cylindrical type, circular platform type flexible seals by 4-5 hour, its density is 1.4-
1.5, hardness HB80-90.
The sheet copper of 1.2mm-1.8mm thickness is coated at shaping circular platform type flexible seals both ends, it is remaining molding
Cylindrical type flexible seals use the netted cladding of flexible steel wire.
The sheet copper is handled by high tempering heat treatment process.Compared to the prior art, the present invention have with
Lower beneficial effect：
1st, the processing method greatly improves the resistance to elevated temperatures of sealing material, meets heavy oil wells steam injection and production requirement.
2nd, graphite-based with the addition of reinforcement steel wire, make the increase of its sealing intensity.
3rd, the sheet copper of cladding is due to certain ductility, can extruded anisotropic graphite be deformed, can set
In casing wall.
4th, the netted cladding of flexible steel wire avoids being squeezed the separation of powdered graphite, it is ensured that leakproofness.
