Abstract
The invention discloses injection well fuse delivery device and method, wherein device includes the center-pole that seal nipple, upper and lower penetration type installed in shaft mouth anti-blowout pipe upper end are enclosed in seal nipple, the lock claw for being connected to seal nipple lower end and being enclosed on simultaneously on the outside of center-pole hypomere, the center-pole lower end outside face is designed as corresponding trochoidal surface with lock claw lower end inside face, the axial movement that the center-pole passes through itself, its conical outside face hard squeeze lock claw conically-shaped inside surface, outwards struts lock claw and inside return.Present invention completely avoids the annular groove of flashboard existing for prior art to be expressed to the problem of tripping in that gate normally-open can not influence fuse is caused in fuse lower end.
Description
Technical field
The present invention relates to core during a kind of injection well fuse delivery device, specifically oil field injection well testing allotment
Sub- delivery device and method.
Background technology
Injection well, all can carry out operation with pressure in order to keep wellbore pressure to prevent stratum is returned from telling when testing allotment.Test
After the completion of need to change water nozzle by water distributing core again lower going-into-well according to test result, specific operation sequence is to close test
Gate, production gate is opened, remove the seal nipple of lubricator upper end, fuse is put into lubricator, then reinstalled
The seal nipple of lubricator upper end, finally opens test strobe, allows fuse to enter in tubing string.Following ask in operation be present
Topic：Because the flashboard two sides of shaft collar is respectively symmetrically welded with a lip ring, in lubricator after input fuse under fuse
Correct in the annular groove of the seal of flashboard, in gate opening, the annular groove of flashboard is expressed to fuse lower end and caused
Gate can not it is normally-open influence fuse tripping in, if firmly open easily fuse is deformed while is also easy to damage
Flashboard, reduce the sealing and service life of gate.
Through retrieval, similar techniques are not found also, so in view of this, in view of the above-mentioned problems, proposing a kind of reasonable in design
And solve the injection well fuse delivery device of above-mentioned missing, while draw the delivering method of the device.
The content of the invention
It is an object of the invention to provide injection well fuse delivery device, it is entirely avoided flashboard existing for prior art
Annular groove is expressed to the problem of tripping in that gate normally-open can not influence fuse is caused in fuse lower end.
In order to reach above-mentioned purpose, present invention employs following technical scheme, injection well fuse delivery device, including installation
Center-pole that seal nipple, upper and lower penetration type in shaft mouth anti-blowout pipe upper end are enclosed in seal nipple, it is connected under seal nipple
Hold and be enclosed on the lock claw on the outside of center-pole hypomere simultaneously, the center-pole lower end outside face is designed as phase with lock claw lower end inside face
Corresponding trochoidal surface, the center-pole pass through the axial movement of itself, its conical outside face hard squeeze lock claw circular cone
Shape medial surface, lock claw is outwards strutted and inside return.
The center-pole is threadedly coupled with seal nipple and can sealed in seal nipple internal rotation by pivot bar
Moved to axial in joint.
The lock claw opens up the more valve structures only connected in root of at least two flutings for longitudinal direction.
The lock claw lower end outside is opened up for strengthening the lock tooth to the dentation of fuse grip.
Position-limitting pin is additionally provided with the center-pole outer wall.
Sealing ring is provided between the center-pole and seal nipple.
In order to reach above-mentioned another object, present invention employs following technical scheme, utilizes injection well fuse delivery device
The method for carrying out delivering fuse, its step are, when delivering fuse, the seal nipple of lubricator upper end are removed first, by fuse set
On the outside of the lock claw of delivery device, axially opposing movement occurs in seal nipple for pivot bar, center-pole lower end outer wall with
Lock claw inwall contacts, and continues to rotate to strut lock claw to touch fuse inwall, fuse is fixed by support force, and delivery device is whole
The upper end that body is together installed to lubricator together with the fuse fixed tightens, and opens test strobe, reversely rotates center-pole and withdraws
Lock claw discharges fuse, allows fuse to be directly entered in tubing string, completes the distributing procedure of fuse.
Compared to prior art, the invention has the advantages that：
The delivery mode of fuse when the present invention changes test allotment, specific operation sequence are to close test strobe, are beaten
Production gate is opened, the seal nipple of lubricator upper end is removed, fuse is enclosed in the lock claw of dropping feeder, pivot bar struts lock
Pawl fixes fuse, and the upper end that dropping feeder is installed to lubricator tightens, and opens test strobe, reversely rotates center-pole and withdraws lock
Pawl discharges fuse, allows fuse to be directly entered in tubing string, and fuse is delivered smoothly, is also less likely to be damaged flashboard.
Brief description of the drawings
Fig. 1 is the structural representation of the injection well fuse delivery device of the present invention.
Embodiment
Detailed description for the present invention and technology contents, coordinate brief description of the drawings it is as follows, but accompanying drawing only provide reference with
Purposes of discussion, not it is used for being any limitation as the present invention.
Referring to the drawings 1, injection well fuse delivery device, including center-pole 1, seal nipple 2, position-limitting pin 3, lock claw 4, institute
State seal nipple 2 and be arranged on shaft mouth anti-blowout pipe upper end, center-pole 1 is threadedly coupled with seal nipple 2, seal nipple 2 and the spiral shell of lock claw 4
Line connects, and the center-pole lower end outside face is designed as corresponding trochoidal surface, the center with lock claw lower end inside face
Bar is by the axial movement of itself, its conical outside face hard squeeze lock claw conically-shaped inside surface, lock claw is outwards strutted and
Inside return.Fluting is machined with the longitudinal direction of lock claw 4 lock claw 4 is divided into the connected several valves in root, the lower end of lock claw 4 is machined with dentation
Tooth is locked, position-limitting pin 3 is arranged on center-pole 1.
The method for carrying out delivering fuse using injection well fuse delivery device, its step are when delivering fuse, to remove first
The seal nipple of lubricator upper end, fuse is enclosed in the lock claw 4 of dropping feeder, pivot bar 1 occurs relatively with seal nipple 2
Mobile, the lower end of center-pole 1 contacts with the inwall of lock claw 4, continues to rotate to strut lock claw 4 to fix fuse, dropping feeder is integrally connected
The upper end that lubricator is together installed to the fuse fixed tightens, and opens test strobe, reversely rotates center-pole 1 and withdraws lock claw
