Detailed description of the invention
It should be noted that in the case of not conflicting, in embodiment in this utility model and embodiment
Feature can be mutually combined.
Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
The present embodiment relates to a kind of top packing extension hanger, and it includes hanger, is connected to hanger top
The packer in portion, and the running tool being connected with packer.Wherein, as it is shown in figure 1, hanger includes
Hanger body 13, the tapered sleeve 14 being located at hanger body 13 upper end and the slips 15 connected with tapered sleeve 14,
Hanger also includes the fluid cylinder 16 being located at hanger body 13 lower end, and is also provided with on hanger body 13
With centralizer 17.
As shown in Figures 2 and 3, packer then includes tie-back sleeve 1, and by packoff nipple 2 and tieback
The packer body 3 that cylinder 1 is connected, connects on packer body 3 and has setting sleeve 5, in setting sleeve 5 also
It is provided with anti-retrogression ratchet 6.Setting sleeve is positioned on packer body 3 via setting shear pin 4, and
Packer also further includes on packer body 3 that location is arranged sets packing element with setting sleeve 5 connects
8, and set the lining 9 that packing element 8 connects, and the deblocking overcoat 11 connected with lining 9.At deblocking overcoat
11, lining 9 and be also additionally provided with the deblocking inner sleeve 10 connected with setting sleeve 5 in setting packing element 8.
In the present embodiment, setting sleeve 5 and deblocking inner sleeve 10 also for being circumferentially located in packer originally via flat key 7
On body 3, between deblocking inner sleeve 10 and deblocking overcoat 11, then it is provided with axial position block, and at packer
It is provided with between body 3 and deblocking overcoat 11 and deblocking overcoat 11 can be carried out circumferentially positioned lock dog, in deblocking
The deblocking shear pin 12 that deblocking inner sleeve 10 is positioned it also is provided with between set 10 and packer body 3.
Also being provided with the axial arranged groove along tie-back sleeve 1 on the inwall of tie-back sleeve 1, groove can be used for and unseal
Tool transmission connects.
As shown in Figure 4 and Figure 5, it includes lifting pipe 18 structure of running tool, is connected to lift pipe 18
On have set block 21 set adapter 19, set block 21 via the upper retainer ring 20 being positioned at its two ends
Being positioned at lower retainer ring 22 sets on adapter 19, is setting block 21 and is setting between adapter 19 then
It is provided with spring.Lifting pipe 18 also connects via double female joints 23 and has back-off joint 27, connect at back-off
27 are provided with the support seat 25 and back-off nut 26 connected, and support seat 25 via back-off bearing 24 with
Double female joints 23 connect.Running tool also includes the central canal 28 being connected with back-off joint 27, at central canal
28 are provided with seal box 29, and then connecting in the end of central canal 28 has rubber plug joint 30.
This top packing extension hanger in use, transfer pitching after putting in place and build the pressure, thus can cut by hanger
Disconnected fluid cylinder shear pin and promote the up hanger that realizes of slips 15 to sit and hang.Hanger is sat after hanging into, passes through
Running tool rotating forward feeding drilling tool realizes machinery and gives up.
The block 21 that sets set on adapter 19 in running tool is in compressive state after assembling completes,
Carry running tool on after having given up, automatically open when setting after block 21 is suggested tie-back sleeve 1, more lower force feed
Entering drilling tool, the block 21 that sets set on adapter 19 is pressed in the top of tie-back sleeve 1, by under press setting sleeve
5 and can cut off and set shear pin 4.Because setting sleeve 5 uses flat key 7 circumferentially positioned with deblocking inner sleeve 10,
Being positioned by axial position block between deblocking inner sleeve 10 and deblocking overcoat 11, deblocking inner sleeve 10 is also by solution
Envelope shear pin 12 is positioned on packer body 3, and the lower surface of lining 9 is also by deblocking overcoat 11
Axially location.During setting, setting sleeve 5 moves axially along packer body 3, and setting sleeve 5 is descending
And packing element 8 can be set, to realize packer setting with lining 9 extruding.
In packer setting, because being provided with anti-retrogression ratchet 6 in setting sleeve 5, in the descending realization of setting sleeve 5
Carry running tool on after setting also will not unseal.And when needs unseal, under enter unsealing tool insert tie-back sleeve
At groove in 1, rotating forward drilling tool, unsealing tool can drive tie-back sleeve 1 and setting sleeve 5 to rotate, and pass through
Flat key 7 transmits moment of torsion and deblocking inner sleeve 10 can be driven to rotate.Due to deblocking overcoat 11 and packer body 3
Between circumferentially positioned by lock dog, thus unseal inner sleeve 10 and deblocking overcoat 11 between produce relative rotation, and solve
Envelope inner sleeve 10 also can cut off deblocking shear pin 12.After rotating forward 1/4th circles, deblocking inner sleeve 10 with
Axial position block between deblocking overcoat 11 disengages, and now deblocking overcoat 11 can be along packer body 3 axle
Deblocking is realized to descending movement.After removing seal for packer, the salvaging of hanger can be carried out.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model,
All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all
Within protection domain of the present utility model should be included in.
