Description
Technical field
This utility model is related to a kind of downhole tool in oil field, more particularly, to a kind of blanking plug of oil pipe.
Background technology
In order to carry out various operations to oil well in the case of no killing well, need oil pipe is blocked, to seal oil pipe
Interior passage, intercepts the down-hole pressure in oil pipe, and this is accomplished by putting into blanking plug to down-hole, and makes blanking plug in shaft bottom using card
Watt seal with oil pipe tube wall clamping positioning and using packing element and tube inner wall swelling, that is, need to realize the seat in down-hole for the blanking plug
Block and set.The input of conventional blanking plug and realize down-hole sit card with set needs using continuous pipe, blanking plug is transported to
Down-hole, and provide higher operation pressure in well head, implement ground well head using continuous pipe and suppress to realize, or utilize from well head
Steel wire is putting into blanking plug, and puts into steel wire powered tools impact blanking plug to realize, and so, is necessary for joining on well
Standby, throw in blanking plug and steel wire instrument using steel wire winch or provide pressure using pump truck, its operation process is complicated, all
Phase length, high cost.
Utility model content
For the above-mentioned deficiency existing for prior art, technical problem to be solved in the utility model is to provide one kind to hit
Hit formula tubing plug, it special uphole equipment need not be thrown in and sat card and set, easy to use, efficiency high.
In order to solve above-mentioned technical problem, a kind of impacting type tubing plug of the present utility model, including from the top down according to
The slip spider of secondary connection, slips, cone, packing element and glue tube base, are connected with guide way in described glue tube base lower end, in described slips
Seat on be connected with connecting tube, described slips, cone, packing element and glue tube base set are inserted in connecting tube, described slip spider, connecting tube and
Guide way set is inserted on center-pole, and connecting tube lower end is provided with piston portion, described center-pole, guide way and connecting tube lower end
Piston portion constitutes the air chamber of sealing, leads to outside the gap between piston portion upper surface and glue tube base lower surface and guide way；
It is provided with shackle member between glue tube base and connecting tube, center-pole is arranged fluted, shackle member can fall on center-pole
In groove.
In said structure, due to being connected with guide way in described glue tube base lower end, the company of being connected with described slip spider
Adapter, described slips, cone, packing element and glue tube base set are inserted in connecting tube, and described slip spider, connecting tube and guide way set are inserted in
On center-pole, connecting tube lower end is provided with piston portion, the piston portion composition of described center-pole, guide way and connecting tube lower end is close
The air chamber of envelope, leads to outside the gap between piston portion upper surface and glue tube base lower surface and guide way, then piston portion upper end
Under down-hole pressure effect outside in guide way for the gap between face and glue tube base lower surface, corresponding axial action can be produced
Power, this axial force is made up of the air chamber of sealing, the company of making by compressing the piston portion of center-pole, guide way and connecting tube lower end
Axially opposing displacement is produced, such that it is able to driving slip spider and glue tube base opposite between the adapter piston portion of lower end and guide way
OK, so that slips is flared out in the presence of cone and block tube inner wall, and make packing element produce footpath under the extruding of glue tube base
Increase and seal the gap between blanking plug and oil pipe so that oil pipe obtains sealing blocking to deformation, diameter.Again due in packing element
It is provided with shackle member between seat and connecting tube, center-pole is arranged fluted, shackle member can fall in the groove on center-pole,
Then before blanking plug seat card sets, it is connected by shackle member kayser between glue tube base and connecting tube, even piston portion upper surface
It is also impossible between the two produce relative displacement under the down-hole pressure effect outside in guide way and glue tube base lower surface between,
Be impossible to automatically to sit card with the increase of down-hole pressure and set, so do not need any equipment control just can relievedly by
Blanking plug from well head directly throw, and can guarantee that oil pipe bottom smoothly rendered to by blanking plug, and after blanking plug completes to throw in,
Only need to act on center-pole by weight, make center-pole descending, such shackle member can fall in the groove on center-pole, piston
Just relative displacement can be produced under down-hole pressure effect outside in guide way between portion upper surface and glue tube base lower surface, thus
Realize the seat card of blanking plug and set, the input of weight is controlled by again without any equipment, easy to use, efficiency
High.
