Description
Technical field
It the utility model is related to a kind of mechanical-vibration type sliding sleeve switch instrument, category Oil/gas Well underground operation tool field.
Background technology
Exploit at home in unconventional straight well or small Wells multistage pressing crack construction at present, typically using open hole packer
The mode of fracturing sliding bush is coordinated to carry out staged fracturing, some payzones meeting water outlet after construction terminates oil recovery a period of time, now such as
Water layer is shut not in time, it will cause the serious consequence of waterflood.So it can typically use switchable pressure in construction
Sliding sleeve is split, the special switching tools of tripping in are turned off when needing to close.
Opening or closing these circulation slide sleeves or switchable fracturing sliding bush just needs to use the switch of dimension model
Instrument.Conventional hydraulic selector instrument typically by coiled tubing tripping in, come realize suppress, put-on and delegated operation carrys out switching sliding sleeve.
This switching tools are cumbersome, can not accurate judgement switching sliding sleeve whether succeed.Coiled tubing and corollary equipment cost are high, account for
Big with site area, resource allocation is difficult.
The content of the invention
The purpose of this utility model is：It is simple in construction, easy to operate to provide one kind, and duty cycle is short, it is existing to solve
Have that switching tools are cumbersome, can not the whether successful problem of accurate judgement switching sliding sleeve mechanical-vibration type sliding sleeve switch instrument.
The technical solution of the utility model is：
A kind of mechanical-vibration type sliding sleeve switch instrument, it is made up of mandrel, joint, elastic claw and switch semi-ring, its feature
It is：The threaded one end of mandrel is provided with joint, is fixed between joint and mandrel by holding screw, joint and mandrel radial direction
Between elastic claw is provided with by shear pin, switch semi-ring is provided with by upper baffle ring and lower baffle ring on the mandrel of joint side,
Spring is provided between switch semi-ring and mandrel.
Pilot hole is provided with described switch semi-ring.
One end of described spring is connected with elastic claw, and the other end of spring is extended in pilot hole.
The beneficial effects of the utility model are：
When the mechanical-vibration type sliding sleeve switch instrument works, by the specified location in steel wire rope lower going-into-well, make switch half
Ring is stuck in the groove of corresponding circulation slide sleeve or switchable fracturing sliding bush.Tripping in carries out jarring up or down afterwards in place,
In the presence of jarring force, the switching tools are moved upwardly or downwardly, so as to drive inner sliding sleeve displacement up or down to realize to cunning
Set is turned on and off.With the characteristics of simple in construction, easy to operate, duty cycle is short, solves existing switching tools operation
It is cumbersome, can not accurate judgement switching sliding sleeve it is whether successful the problem of, provided for the completion convenience and accuracy of Oil/gas Well
Power supports.

Embodiment
The mechanical-vibration type sliding sleeve switch instrument is made up of mandrel 1, joint 2, elastic claw 3 and switch semi-ring 4, mandrel 1
Threaded one end is provided with joint 2, is fixed between joint 2 and mandrel 1 by holding screw 5, leads between joint 2 and the radial direction of mandrel 1
Cross shear pin 6 and elastic claw 3 is installed, switch semi-ring is provided with by upper baffle ring 7 and lower baffle ring 8 on the mandrel 1 of the side of joint 2
4, switch and be provided with pilot hole 10 on semi-ring 4.Spring 9 is provided between switch semi-ring 4 and mandrel 1；One end of spring 9 and bullet
Property pawl 3 is connected, and the other end of spring 9 is extended in pilot hole 10.Switch semi-ring 4 is the burst zero of semicircular belt profile feature
Part, it can expand or be shunk in the presence of external force in the presence of spring 9（Referring to accompanying drawing 1）.
When the mechanical-vibration type sliding sleeve switch works, according to the circulation slide sleeve or switchable fracturing sliding bush for being preset at underground
Well depth data determines depth of setting, and after specified location is transferred to, ground is stuck in by instrument upward jarring, switch semi-ring 4
In the groove of circulation slide sleeve or switchable fracturing sliding bush.The shoulder now switched on semi-ring 4 drives inner sliding sleeve to transport up or down
It is dynamic, realize the displacement up or down to inner sliding sleeve.When inner sliding sleeve displacement shape journey reaches design load, inside sliding sleeve top connection
The inclined-plane of inclined-plane extruding switch semi-ring 4 upper end, retracts after making the compression spring 9 of switch semi-ring 4, smoothly acts switching tools（Referring to
Accompanying drawing 2-3）.
The mechanical-vibration type sliding sleeve switch instrument has the characteristics of simple in construction, easy to operate, duty cycle is short, solves
Existing switching tools are cumbersome, can not accurate judgement switching sliding sleeve it is whether successful the problem of, be Oil/gas Well completion convenience
Powerful support is provided with accuracy.
