Specific embodiment
Embodiment 1:
Present embodiments provide a kind of mechanical reciprocating shocking type flow controller unsealing tool, including connector 1, fishing neck 2, pipe nipple
7, outer cylinder 16 and bailer grab 14, the fishing neck 2 and pipe nipple 7 are set in from top to bottom on connector 1,16 upper end of outer cylinder with it is short
7 connection of section, 16 lower end of outer cylinder are connect with bailer grab 14, and the connector 1 can lower movement vertically；
It is equipped with locking structure in the connector 1, is equipped with trip rod in the pipe nipple 7 and outer cylinder 16, the trip rod can edge
Axial to move up and down, the lower end of the locking structure is connect with trip rod, and the trip rod is by under trip rod top 8 and trip rod
Portion 15 forms, and 8 diameter of trip rod top is less than 15 diameter of trip rod lower part, and the trip rod top 8 is arranged with impact bullet
Spring 9.
The course of work: when going into the well, which is connect in basic tool string lower part.After transferring to flow controller setting position top,
Slowly decentralization.After bailer grab 14 catches flow controller top fishing neck 2, tool string is above mentioned, taut wire, connector 1 can be due to locking
The card resistance power of structure slowly moves up, and until being moved to 7 top of pipe nipple release vacancy, impact spring 9 is merged by compression at this time, when connecing
First 1 separates with trip rod top 8, and trip rod top 8 is divided drives trip rod lower part 15 to divide under 9 compression force of impact spring
It is hit under quickly, impact force is generated to flow controller mandrel 12.Then, tool string is slowly transferred, reenters locking structure to connector 1
Interior reset, above mentions again, continues to hit impact force under generating.Repeatedly for several times, it can be achieved that machinery be move in circles shock movement,
Until flow controller unseals.
Embodiment 2:
On the basis of embodiment 1, a kind of mechanical reciprocating shocking type flow controller unsealing tool is present embodiments provided, is also wrapped
Mandrel 12 is included, the mandrel 12 is set to the annular space between outer cylinder 16 and trip rod, and the outer cylinder 16 is with mandrel 12 by cutting
Pin 13 connect, the mandrel 12 from top to bottom be equipped with mandrel nut 10 and main spring 11, the bailer grab 14 by sliding block 18 with
Outer cylinder 16 connects, and is arranged with secondary spring 17 above the sliding block 18.
If for a long time can not still unseal flow controller, can quickly under hit, cut off 13, make mandrel 12 can be with respect to 16 axis of outer cylinder
To movement, during hitting due under, main spring 11 is compressed, and under the action of main spring 11 and secondary spring 17, outer cylinder 16 is logical
Crossing sliding block 18 drives bailer grab 14 to move upwards, and puts the top fishing neck of flow controller aside, acts tool string.
Embodiment 3:
On the basis of embodiment 2, a kind of mechanical reciprocating shocking type throttling as shown in Figure 1 and Figure 2 is present embodiments provided
Device unsealing tool, the locking structure include closing piece 3 and closing piece set 4.
4 lower section of closing piece set is equipped with spring base 6, is equipped with spring 5 between the closing piece set 4 and spring base 6.
The spring base 6 is connect with trip rod by straight pin 19.
The pipe nipple 7 is connected through a screw thread with outer cylinder 16.
As shown in Figure 1 and Figure 2, connector 1 is engaging in closing piece set 4 by closing piece 3, and spring 5 is pressed on spring base 6, uses straight pin
Spring base 6 is divided with trip rod top 8 and connect by 19, and outer cylinder 16 and fishing neck 2 are threadedly coupled rear enclosure on connector 1, impact spring 9
It covers to divide on trip rod top 8 and be compressed with trip rod lower part 15.Mandrel 12 passes through outer cylinder 16 and connect the main bullet of compression with mandrel nut 10
Spring 11, then it is fixed with soket head cap screw 20, it prevents from loosening.Finger catcher, which is covered, to be fixed on outer cylinder 16 with sliding block 18, and outer cylinder 16 uses spiral shell
Line and pipe nipple 7 connection compress secondary spring 17, outer cylinder 16 with cut off 13 and mandrel 12 connection.
Spring 5 is mounted under closing piece set 4, provides pretightning force for the reset of closing piece 3.Impact spring 9 is mounted on 7 lower part of pipe nipple,
And cover on trip rod top 8, it is the core of vibration deblocking strength.Trip rod lower part 15 connects in vibration bar top lower end,
The vibration rigid body of deblocking flow controller is hit in trip rod lower part 15 under being, directly hit with flow controller mandrel 12.
Fishing tool string: steel wire for logging+rope socket+weighted lever+mechanical reciprocating jar+bailer grab 14；
After fishing tool string transfers to flow controller setting position top, slowly transfer.Bailer grab 14 catches flow controller top
After fishing neck 2, tool string is above mentioned, taut wire, connector 1, which will be slow, to be moved up, until closing piece 3 is moved to 7 top of pipe nipple release sky
Behind position, connector 1 is separated with trip rod top 8, is hit under trip rod is quick under 5 compression force of spring, to flow controller mandrel 12
Generate impact force.Then, tool string is slowly transferred, is reentered in closing piece set 4 to connector 1, after closing piece 3 resets.Again it above mentions,
Continue to hit impact force under generating.Repeatedly for several times, it can be achieved that machinery is the shock movement that moves in circles, until flow controller unseals.
If can not still unseal flow controller for a long time, can quickly under hit, cut off 13, bailer grab 14 is given up flow controller top
Fishing neck acts tool string.
In conclusion the mechanical reciprocating shocking type flow controller unsealing tool, can achieve following effect:
1. shock deblocking power is hit under to be generated under the acceleration of impact spring 9, not by steel wire for logging elastic reaction
It influences, therefore can produce biggish impact force, effect, which is better than under routine, hits impact force；
2. hitting in knockout process under, bailer grab 14 will not actively give up, and may be implemented to hit under under multiple seized condition
Deblocking effect；
3. impact force is hit under the generation that can continue for being difficult to the flow controller unsealed, it, can in the case where shock is repeated several times
To realize the deblocking of flow controller.
Exemplified as above is only to the utility model for example, not constituting to the protection scope of the utility model
Limitation, within all designs the same or similar with the utility model all belong to the scope of protection of the present invention.
