Embodiment
The utility model is more fully illustrated below with embodiment.The utility model can be presented as it is a variety of not
Same form, it is not construed as being confined to the exemplary embodiment described here.
For ease of explanation, space relative terms such as " on ", " under " " left side " " right sides " can be used herein, for saying
The element or feature shown in bright figure is relative to another element or the relation of feature.It should be understood that except in figure
Outside the orientation shown, spatial terminology is intended to include the different azimuth of device in use or operation.If for example, in figure
Device is squeezed, be stated as positioned at other elements or feature " under " element will be located into other elements or feature " on ".Cause
This, exemplary term " under " both upper and lower orientation can be included.Device can be positioned otherwise（It is rotated by 90 ° or is located at
Other orientation）, can correspondingly be explained used herein of the relative explanation in space.
As shown in figure 1, the landing nipple in the present embodiment, includes the first joint 1 and the second joint 3 of tubulose, first connects
First 1 and second joint 3 be threadably secured connection, naturally it is also possible to clamping, or other modes are fixedly connected.
As shown in Fig. 2 the surface of instrument can set elastic card claw structure as positioning claw 4；Position the outer tube wall of claw 4
On be provided with locating flange, locating slot 4-1. locating slots 4-1 is provided with locating flange can be with the first accessory flange 1-1 or
Two accessory flange 3-1 are engaged.The both ends of locating flange are respectively arranged with the first guide surface 4-2 and the second guide surface 4-3.
The first accessory flange 1-1 is provided with the inwall of first joint 1, it is auxiliary to be provided with second on the inwall of the second joint 3
Help flange 3-1；Instruction claw accommodating cavity is provided between first accessory flange 1-1 and the second accessory flange 3-1, indicates claw 2
It can be moved back and forth in the axial direction in instruction claw accommodating cavity.Instruction claw 2 is elastic card claw structure.Indicate the outer wall of claw 2
It is provided with instruction flange 2-2.Manipulation flange 1-2 is provided with instruction claw accommodating cavity inwall.Manipulation flange 1-2 internal diameter is less than
Flange 2-2 external diameter is indicated, is meshed each other.Manipulation flange 1-2 can prevent to indicate that flange 2-2 continues to move；Indicate claw 2 with
When positioning the engagement of claw 4, resistance is conducted to instrument, prevents instrument from moving；Resistance increase can control the mechanisms such as valve element to produce
Life turns off or on action.As manipulation flange 1-2 and indicate that the pressure between flange continues to increase, indicate the tube wall stress of claw 2
Degree of crook increase in backward, instruction flange is set to be moved forward through manipulation flange 1-2.During design, unblock should ensure that
Pressure should be greater than controlling the mechanisms such as valve element to produce the pressure for turning off or on action.
Indicate claw 2 outer wall be provided with instruction flange 2-2, the first accessory flange 1-1, the second accessory flange 3-1 it is interior
Footpath is less than the external diameter of the locating flange of instrument.
Indicate that the inwall rear and front end of claw 2 is respectively arranged with inner side and does not have guide surface, outside sets the first of guide surface
Guiding flange 2-1 and the second guiding flange 2-3.It is smooth when positioning claw is inwardly moved, larger resistance is produced when moving out
Power, give ground installation clear and definite position feedback signal.
In order to reduce resistance and be easy to slip out of the hand, the first accessory flange 1-1 both ends are provided with guide surface；Second auxiliary
Flange both ends are also provided with guide surface.
During specific works, the landing nipple not only has positioning function, is also used as two-way switch instrument.Work as blocker
Tool, when above being carried such as reacting cycle ball-and-seat, locating flange elder generation and the second guiding flange 2- on the positioning claw 4 of reacting cycle ball-and-seat
3 contacts, are passed through, because the direction does not have guide surface, the first guiding flange 2-1 is stuck in locating slot 4- under the guiding of guide surface
In 1, realize that locating flange engages with the first guiding flange 2-1, the instruction pushing tow of claw 2 is moved upwards.
When the instruction flange 2-2 on the instruction outer wall of claw 2 contacts with the manipulation flange 1-2 on accommodating cavity wall, generation hinders
Mechanical resistance is stopped wellbore tool reacting cycle ball-and-seat and moved upwards；When wellbore tool reacting cycle ball-and-seat continues above to carry, it can produce bigger
Resistance, when resistance, which is more than reacting cycle ball-and-seat, closes required size, now reacting cycle ball-and-seat is forced to close.
When continuing above to carry, manipulation flange 1-2 extruding instruction flange 2-2, the pressure of increase makes instruction claw 2 start to become
Shape, caliber reduce, and continue through manipulation flange 1-2 up.
First guide surface 4-2 of positioning claw 4 contacts with the first accessory flange 1-1 of the first joint 1, passes through the first auxiliary
Flange 1-1 extrudes locating flange, reduces the caliber of positioning claw 4, and the first of the instruction claw 2 of locating flange and landing nipple draws
Pilot edge 2-1 engagements depart from, and now weight indicator can observe this huge power of slipping out of the hand on well, so as to judge the position of whole tubing string
Put, now continue above to carry, the locating flange of reacting cycle ball-and-seat can disengage at the big path of the first joint 1, anti-so as to realize
Circulation ball-and-seat is completely disengaged with lower landing nipple.
Action and display when when reacting cycle ball-and-seat is transferred, meeting inverted repeat above carries, it is to close counter follow only above to carry
Ring ball-and-seat, decentralization are to open reacting cycle ball-and-seat.
Two-way landing nipple in the present embodiment：
1st, it can be realized as two-way landing nipple and work as kit（Reacting cycle ball-and-seat）Above carry and being closed, decentralization is opened
Dual-use function.
2nd, it can guarantee that kit as two-way landing nipple（Reacting cycle ball-and-seat）Realize when transferring and above carrying and first close
Reacting cycle ball-and-seat is slipped out of the hand again.
3rd, can be to operate to be provided with well during reacting cycle ball-and-seat is opened and closed as two-way landing nipple
Power shows and referred to.
4th, two-way landing nipple realizes two-way switch function.
Above-mentioned example is only intended to illustrate the utility model, in addition, also a variety of different embodiments, and these
Embodiment be all those skilled in the art after comprehension the utility model thought it is also envisioned that therefore, no longer arrange one by one herein
Lift.
