In upper figure：Top connection 1, seal I 2, support sliding sleeve 3, piston 4, seal II 5, seal III 6, seal IV
7th, releasing pup joint 8, deblocking pipe nipple 9, set pipe nipple 10, anti-turn screw 11, retaining mechanism 12, steel ball 13, sliding sleeve 14, shear pin of giving up
15th, heart pipe 16, seal V 17.
Specific embodiment
With reference to accompanying drawing 1, the utility model will be further described：
The utility model include top connection 1, support sliding sleeve 3, piston 4, releasing pup joint 8, deblocking pipe nipple 9, set pipe nipple 10,
Anti-turn screw 11, retaining mechanism 12, steel ball 13, sliding sleeve 14 of giving up, shear pin 15, heart pipe 16, have been sequentially connected with the top connection 1
Support sliding sleeve 3 is installed inside releasing pup joint 8, top connection 1 and releasing pup joint 8, shear pin 15 is installed on the releasing pup joint 8,
The support sliding sleeve 3 is connected by the shear pin 15 with releasing pup joint 8, and the bottom of the releasing pup joint 8 is provided with steel ball 13, and
It is connected with sliding sleeve 14 of giving up by steel ball 13, anti-turn screw 11 is installed on the releasing pup joint 8, and anti-turn screw 11 is passed through
Sliding sleeve 14 of giving up is worn, and is higher by the external diameter of sliding sleeve 14 of giving up；The annular of the top connection 1 and the top of releasing pup joint 8 composition is empty
Between internal piston 4 is installed.
Wherein, the outside of releasing pup joint 8 is sequentially provided with sliding sleeve 14 of giving up, heart pipe 16, retaining mechanism 12, deblocking pipe nipple 9
With set pipe nipple 10, the sliding sleeve 14 of giving up is connected with heart pipe 16 by screw thread, and the top of heart pipe 16 is provided with deblocking pipe nipple 9,
The outside of pipe nipple 9 is unsealed to set pipe nipple 10, the downside and retaining mechanism 12 for setting pipe nipple 10 are connected.
In addition, being provided with seal I 2 between the top of support sliding sleeve 3 and top connection 1, bottom and the top connection of sliding sleeve 3 are supported
Seal V 17 is provided between 1, to be supported and be provided with seal IV 7 between the middle and upper part of sliding sleeve 3 and releasing pup joint 8.
The inner chamber of above-mentioned deblocking pipe nipple 9 is pyramidal structure.
Seal II 5 is provided between above-mentioned piston 4 and the inwall of top connection 1, is provided with close between piston 4 and releasing pup joint 8
Sealing III 6.
Refering to Fig. 1, the general step of specific implementation is as follows：When the downhole tool such as packer and bridging plug is constructed in complete design
Program, when needing to give up, can first select to rotate forward back-off and give up mode.When back-off is given up, the construction on the top of top connection 1 is connected to
Tubing string（It is not drawn into figure）The moment of torsion of rotation, passes to releasing pup joint 8, and the anti-turn screw 11 mounted thereto of releasing pup joint 8 is passed
Sliding sleeve 14 of giving up is passed, because giving up sliding sleeve 14 and heart pipe 16 is connected through a screw thread, heart pipe 16 is again and the underground such as packer, bridging plug
The latter half of instrument and oil well pipe are connected, it is impossible to rotate, and sliding sleeve 14 of giving up is made in the torque that anti-turn screw 11 is transmitted
Lower rotation is used, heart pipe 16 is not rotated, make to give up sliding sleeve 14 and heart pipe 16 is disengaged, so as to realize giving up.If when back-off is given up, because
It is by Oil/gas Well casing programme（Such as well bore is in level or High angle shape）Influence, or using packer, gravel pack tools
With tubular column structure, the complex technical process of downhole tool such as bridging plug etc., the torque transmitted when all back-off may be made to give up, it is impossible to have
Effect ground passes to releasing pup joint 8, is insufficient to allow sliding sleeve 14 of giving up to rotate, and cannot also realize giving up sliding sleeve 14 and heart pipe 16 takes off
Open.When back-off is given up to encounter difficulties, can be by way of blocking support sliding sleeve 3 top（It is not drawn into blocking mode figure）,
Suppressed from above, support sliding sleeve 3 is born hydraulic pressure, produce a downward thrust, this thrust on shear pin 15, when this
When thrust reaches the shear strength of shear pin 15, shear pin 15 is cut, and support sliding sleeve 3 glides, and makes to be arranged on the steel ball 13 of releasing pup joint 8
With the Joint failure of sliding sleeve 14 of giving up, i.e. releasing pup joint 8 and the disengaging of sliding sleeve 14 of giving up, so as to realize giving up.
The above, is only preferred embodiment of the present utility model, and any those of ordinary skill in the art may profit
Equivalent technical scheme is changed the utility model or is revised as with the technical scheme of above-mentioned elaboration.Therefore, foundation
Any simple modification or substitute equivalents that the technical solution of the utility model is carried out, belong to the greatest extent what the utility model was claimed
Scope.
