Abstract
The utility model relates to a novel slips for ultradeep well, including the slips body, the preceding terminal surface of the slips body is fixed from top to bottom to set up the dental lamina and this dental lamina is installed in the card slot that the slips body corresponds, and screw fixed mounting dental lamina retaining ring was passed through on the upper portion of terminal surface before this slips was personally experienced sth. Part of the body, and the middle carrier ring of screw fixed connection is passed through at the middle part of terminal surface before this slips body, simultaneously, screw fixed connection bottom carrier ring is passed through to the bottom of terminal surface before the slips body to subregion ring structure has been formed in dental lamina top, middle part, bottom. The utility model discloses beneficial effect does: through carrier ring in the middle of addding with bottom carrier ring and the two bears axial load respectively, make the bearing capacity that overall structure is reasonable, improved the slips, safe and reliable, convenient operation simultaneously, combine the dental lamina retaining ring on upper portion, make that the slips body is gone up in, protecting effect has all been realized separately at lower three position.
Description
Technical field
This utility model relates to a kind of petroleum gas power tool, particularly relates to a kind of novel ultradeep well card
Watt.
Background technology
At present, the instrument that drilling well is used is a lot, is broadly divided into rig tool and down-hole equipment.Rig tool
For playing the lower and upper instrument unloading drilling tool, such as tongs, elevator, slips etc., tongs is used for, unloads all kinds of going into the well
Thread of drilling tool, elevator is in order to hang, promote and to transfer drill string, and slips is used for blocking drill string and being suspended on rotating disk
On.
During oilfield drilling, completion practice, especially remove in single upright column or casing job,
It is required to fix drilling rod or sleeve position by slips, in order to carry out upper button, shackle operation, therefore, card
Watt ease for operation and safety become be particularly important.Currently for drill pipe slip fixing mainly with
Three-chip type manual slip is main, during manual operation, needs three people to lift simultaneously and draws, and when upper slips operates,
Need three people to coordinate to be directed at drilling rod by slips opening, after slips is blocked drilling rod, then joined with driller by three people
Close and slips is stuck on the certain altitude of drilling rod, in order to facilitate upper button and the shackle operation of hydraulic tongs；Unloading card
Watt operation time, it is still necessary to utilize and on drilling rod, carry inertia, slips is carried away simultaneously and is placed on shaft mouth side mend core.
This case is it is important to note that above comprised slip system and existing petroleum gas bore
The slips used in well operations, its dental lamina directly contacts with slips body dental lamina bottom land, and all load are by slips body
Bottom land bears, and all lacks the safeguard procedures of correspondence at position, three, slips body upper, middle and lower, due to size and
The restriction of structure, the bearing capacity of slips is on the low side, is not suitable for the job requirements of ultradeep well.
Therefore, for the above, need prior art is reasonably improved.
Utility model content
For disadvantages described above, this utility model offer one is rational in infrastructure, can significantly improve bearing capacity, safety
Reliably, easy to operate novel ultradeep well slips, to solve many deficiencies of prior art.
For achieving the above object, this utility model is by the following technical solutions:
A kind of novel ultradeep well slips, including slips body, described slips body front end face is fixing from top to bottom to be set
Putting dental lamina and this dental lamina is arranged in the board slot that slips body is corresponding, spiral shell is passed through on the top of this slips body front end face
Nail fixedly mounts dental lamina back-up ring, and carrier ring in the middle of connection is fixed by screw in the middle part of this slips body front end face,
Meanwhile, carrier ring bottom connection is fixed by screw in the bottom of described slips body front end face, thus on dental lamina top
Portion, middle part, bottom define subregion back-up ring structure.
Correspondingly, described dental lamina back-up ring is depressed in slips surface；Described bottom carrier ring is arranged under dental lamina
End.
Having the beneficial effect that by setting up middle carrier ring of novel ultradeep well slips described in the utility model
With bottom carrier ring and the two be respectively subjected to axial load, make reasonable integral structure, improve holding of slips
Loading capability, safe and reliable, easy to operate, meanwhile, in conjunction with the dental lamina back-up ring on top, make on slips body, in,
Lower three positions the most each achieve protection effect.

Detailed description of the invention
Embodiment 1
As shown in Figure 1-2, the novel ultradeep well slips described in this utility model embodiment, including slips body 3,
Described slips body 3 front end face be from top to bottom fixedly installed dental lamina 5 and this dental lamina 5 to be arranged on slips body 3 right
In the board slot answered, the top of this slips body 3 front end face fixedly mount dental lamina back-up ring 1 by screw 2 so that
Block dental lamina 5, the middle part of this slips body 3 front end face connect by screw 2 is fixing in the middle of carrier ring 4 so that
In blocking dental lamina 5 in the middle part of slips body 3, meanwhile, the bottom of described slips body 3 front end face is again by screw 2
Bottom fixing connection, carrier ring 6 is so that block dental lamina 5 bottom slips body 3, thus defines at dental lamina 5
Back-up ring is all set up in top, middle part, bottom, and the dental lamina 5 for different modes composition can improve bearing capacity.
Embodiment 2
As shown in Figure 1-2, the novel ultradeep well slips described in this utility model embodiment, including slips body 3,
Described slips body 3 front end face be from top to bottom fixedly installed dental lamina 5 and this dental lamina 5 to be arranged on slips body 3 right
In the board slot answered, the middle part of this slips body 3 front end face connect by screw 2 is fixing in the middle of carrier ring 4 so that
In blocking dental lamina 5 in the middle part of slips body 3, meanwhile, the bottom of described slips body 3 front end face is again by screw 2
Bottom fixing connection, carrier ring 6 is so that block dental lamina 5 bottom slips body 3.
The above-mentioned description to embodiment is for the ease of those skilled in the art it will be appreciated that and answer
Using this case technology, these examples obviously can be made various amendment by person skilled in the art easily, and
General Principle described herein is applied in other embodiments without through performing creative labour.Therefore,
This case is not limited to above example, and those skilled in the art, according to the announcement of this case, makes for this case
Improve and amendment all should be in the protection domain of this case.
