Description
Technical field
The utility model high pressure sealing packing box belongs to oil recovery auxiliary equipment field.
Background technology
Packing is to be installed at oil-extractor polish-rod and wellhead packing box annular space, prevents polished rod when moving back and forth in well head
The excessive encapsulant of mixture such as oil, gas and water.
When oil producing operation is carried out, during oil well closing well high due to bottom pressure, easily there is well head packing leakage phenomena, make
Resulting mixture is excessive；When on the other hand being recovered the oil using steam driving exploitation technology, to reduce Viscosity of Heavy Crude Oil, by injecting during operation
Well to oil reservoir fill steam to improve viscous crude temperature, so stewing well stage underground high-voltage high temperature fluid also can to packing cause compared with
Big pressure, and then cause well head packing to be missed, detract tolerance, it is unfavorable for volume increase.
Utility model content
In order to solve the above problems, the utility model provides a kind of high pressure sealing packing box, and the instrument can be effectively right
Wellhead sealing, it is to avoid detraction tolerance.
What the purpose of this utility model was realized in：
High pressure sealing packing box, including high pressure sealing mould, two fixing bolts and airtight and watertight padding composition；
Described high pressure sealing mould includes cartridge type mould and is symmetricly set on two of cartridge type mold bottom along excircle
Connection otic placode, cartridge type mold bottom sets light rod through-hole；
Described fixing bolt includes the collar, screw rod and the nut supporting with screw rod, and screw rod can pass through connection otic placode
Earhole；
Described airtight and watertight padding is able to ensure that cartridge type mould and oil-extractor polish-rod under high temperature and high pressure environment to air seal.
Above-mentioned high pressure sealing packing box, airtight and watertight padding surface scribbles fluid sealant.
Beneficial effect：
The utility model high pressure sealing packing box, when using first by the packing in original packing box add it is good after, then by table
The airtight and watertight padding that face scribbles fluid sealant is added in the cartridge type mould of high pressure sealing mould, and it is upward that high pressure sealing mould is pressed into cylinder bottom
Mode is finally enclosed within original packing box above original packing box with the collar of two fixing bolts, and screw rod is passed through and connected
Fastened using nut after ear connecting plate, complete the secondary seal to well head.
The utility model high pressure sealing packing box, is aided in using high pressure sealing packing box is added on original packing box
The mode of sealing, adds in high pressure sealing packing box and scribbles sealant sealing filler, and carries out outside adding using fixing bolt
Gu, not only tightness is high, while avoid changing original equipment again, saves production cost；The other device volume is small, carries
It is convenient, alleviate the labour intensity of operating personnel.
Brief description of the drawings
Fig. 1 is the structure chart of the utility model high pressure sealing packing box.
Fig. 2 is the top view of the utility model high pressure sealing packing box high pressure sealing mould.
In figure, 1 high pressure sealing mould, 11 cartridge type moulds, 12 connection otic placodes, 2 two fixing bolts, 21 collars, 22 screw rods,
23 nuts, 3 airtight and watertight paddings.
Specific embodiment
The utility model specific embodiment is described in further detail below in conjunction with the accompanying drawings.
Specific embodiment one
The high pressure sealing packing box of the present embodiment, structural representation as shown in Figure 1 and Figure 2, including high pressure sealing mould 1, two
Individual fixing bolt 2 and airtight and watertight padding 3 are constituted；
Described high pressure sealing mould 1 includes cartridge type mould 11 and is symmetricly set on the bottom of cartridge type mould 11 along excircle
Two connection otic placodes 12, the bottom of cartridge type mould 11 sets light rod through-hole；
Described fixing bolt 2 includes the collar 21, screw rod 22 and the nut 23 supporting with screw rod 22, and screw rod can be through company
The earhole of ear connecting plate 12；
Described airtight and watertight padding 3 is able to ensure that cartridge type mould 11 is close to gas under high temperature and high pressure environment with oil-extractor polish-rod
Envelope.
The utility model high pressure sealing packing box, when using first by the packing in original packing box add it is good after, then by table
The airtight and watertight padding 3 that face scribbles fluid sealant is added in the cartridge type mould 11 of high pressure sealing mould 1, and high pressure sealing mould 1 is pressed into cylinder bottom
Upward mode is finally enclosed within original packing box, spiral shell above original packing box with two collars of fixing bolt 2 21
Bar 22 is fastened after passing through connection otic placode 12 using nut 23, completes the secondary seal to well head.
Specific embodiment two
The Theftproof bolt formula side clamp of the present embodiment, on the basis of specific embodiment one, further limits airtight and watertight padding 3
Surface scribbles fluid sealant.
The sealing of the utility model high pressure sealing packing box is further strengthened in the design.
