Specific embodiment
Embodiment 1:
A kind of hydraulic dauer effect formula flow controller unsealing tool is present embodiments provided, including the connector connected from top to bottom
1, balancing pole 2, the balancing pole 2 are arranged with fishing neck 3 outside, and 3 lower part of fishing neck is connected with pipe nipple 8,3 He of fishing neck
Pipe nipple 8 cuts off 20 connections by first, and 8 lower part of pipe nipple is connected with outer cylinder 13, is equipped with piston 6, institute below the balancing pole 2
It states and is connected with bailer grab 17 under outer cylinder 13；
The balancing pole 2 is equipped with channel 18, and the fishing neck 3 is equipped with air inlet 19, and the air inlet 19 is located at logical
18 lower right of road, the piston 6 is up big and down small, and 6 top of piston is set to 3 lower part of fishing neck, and 6 lower part of piston is set to short
In section 8,6 lower end of piston is connected with trip rod 9.
The course of work:
When going into the well, which can be connect in basic tool string lower part.It slowly goes into the well until on flow controller setting position
Portion.Downward jarring connector 1 first allows bailer grab 17 to catch flow controller top fishing neck, continues downward jarring connector 1, and connector 1 pushes
Balancing pole 2 moves down, and air inlet 19 and channel 18 communicate, and continues downward jarring, top fastening means string and the unsealing tool
It disengages, acts tool string.It drives a well and restores pressure.
Fluid enters 3 inner cavity of fishing neck by air inlet 19 and channel 18, pushes piston 6, until 9 lower part of trip rod is withstood on
In flow controller upper core shaft 12, under the continuous action of Fluid pressure, the lower part of trip rod 9 is persistently to 12 output of flow controller mandrel
Pressure, under the action of long-term, flow controller mandrel 12 gradually generates downward displacement, final to realize flow controller deblocking.
If rise, discovery flow controller is successfully unsealed, and upward jarring, fishing neck 3 is cut first connect with pipe nipple 8 and cut off
20.Balance the 3 inner cavity two-way pressure of fishing neck.Then unsealing tool is played out, unsealing tool and the flow controller being unsealed are together
It rises.
Embodiment 2:
On the basis of embodiment 1, a kind of hydraulic dauer effect formula 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 trip rod 9 and pipe nipple 8 and outer cylinder 13, the outer cylinder 13 and mandrel
14 connections are cut off by second between 12, the mandrel 12 is equipped with soket head cap screw 22, and the mandrel 12 is equipped with mandrel spiral shell
Cap 10 and main spring 11；
The bailer grab 17 is connect by sliding block 16 with outer cylinder 13, and secondary spring is equipped between the outer cylinder 13 and sliding block 16
15。
If rise, discovery flow controller unseal not successfully, can upward jarring, cut outer cylinder 13 connect with mandrel 12 second
14 are cut off, be axially moved mandrel 12 can with respect to outer cylinder 13, during hitting due under, main spring 11 is compressed, in main spring 11
Under the action of secondary spring 15, outer cylinder 13 drives bailer grab 17 to move upwards by sliding block 16, and the top for putting flow controller aside is beaten
Neck is fished out, so that bailer grab 17 is slipped out of the hand, the unsealing tool can be played out.
Embodiment 3:
