The auto Isolator Well Head of adjustable offset, righting oil pipe, control sealing, control blowing and adverse current.
The purpose of this utility model is in view of the deficienciess of the prior art, provide a kind of self-packer, including from capsule
Body and centering ring；The centering ring is arranged in self-styled housing.
Including jackscrew；Top wire hole is provided with the self-styled housing；The jackscrew is arranged in top wire hole.
Including self-sealing rubber core；Spill groove structure is provided with the self-styled housing；The self-sealing rubber core is arranged on spill
In annular groove.
Arc groove structure is provided with the self-styled housing；Protective case is provided with the outside of the arc groove；And it is described
Annular inflatable tire is then provided between arc groove and protective case.
Also include gas tube；The gas tube is connected with annular inflatable tire；Inflation tube chamber is provided with the self-styled housing；
The gas tube is arranged on gas tube intracavitary；The gas tube is also associated with aerating device；It is additionally provided with the self-styled housing
Bolt hole；Bolt is provided with bolt hole.
Preferably, the top wire hole, which exposes mouth, is set to tetragonal structure；Top wire hole is threadedly coupled jackscrew；Top wire hole with
Jackscrew one has four groups and is evenly distributed on self-styled housing.
Preferably, described protective case is set to rubber protecting jacket.
Preferably, the material of the annular inflatable tire is rubber.
Preferably, the bolt hole has six groups and is evenly distributed on self-styled housing with bolt one；And the bolt
Using KYS25/65 production tree flange bolts.
Preferably, being provided with boss on described self-styled housing, described boss thickness is 5cm, and self-styled housing is installed
Afterwards, the height that self-styled housing protrudes from ground is 15cm.
Beneficial effect：The utility model has the advantages that：The protrusion height of ground housing is low in the utility model,
It is easy to operating personnel to operate, works safer；Self-packer is simple in construction, lightweight, is readily transported and installs；Self-packer
There are erection device, adjustable offset, righting oil pipe, it is to avoid OIH pipe eccentric wear packing unit, cause the abrasion aggravation of glue core, lose sealing
Function；Self-packer can make self-sealing rubber core holding oil pipe realize sealing function by the inflation and deflation of annular inflatable tire, unclamp
Oil pipe can be made freely above to carry, transferred, control adverse current, easy to operate well, reliably.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
Fig. 2 is structure top view of the present utility model in Fig. 1.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the utility model is further elucidated, the present embodiment is with the utility model
It is lower premised on technical scheme to be implemented, it should be understood that these embodiments are merely to illustrate the utility model rather than limit this reality
With new scope.
As depicted in figs. 1 and 2, a kind of self-packer, including self-styled housing 1 and centering ring 2；The centering ring 2 is arranged on
In self-styled housing 1.
Including jackscrew 3；Top wire hole 4 is provided with the self-styled housing 1；The jackscrew 3 is arranged in top wire hole 4.
Including self-sealing rubber core 5；The structure of spill annular groove 6 is provided with the self-styled housing 1；The self-sealing rubber core 5 is arranged on
In spill annular groove 6.
The structure of arc groove 7 is provided with the self-styled housing 1；The outside of the arc groove 7 is provided with protective case 8；And
Annular inflatable tire 9 is then provided between the arc groove 7 and protective case 8.
Also include gas tube 10；The gas tube 10 is connected with annular inflatable tire 9；It is provided with and fills in the self-styled housing 1
Tracheae chamber 11；The gas tube 10 is arranged in inflation tube chamber 11；The gas tube 10 is also associated with aerating device 12；It is described from
