Abstract
The utility model discloses a novel pressure is bumped in auto -lock device, glue the bowl including auto -lock seal receptacle, auto -lock core, the plug of giving up the throne, plug core and plug, wherein auto -lock core, the plug of giving up the throne, plug core and plug are glued the bowl and are installed in the inner chamber of auto -lock seal receptacle, the setting of auto -lock core in the front, the plug core is connected with the auto -lock core through the plug of giving up the throne, the plug is glued the bowl and is overlapped and establishes on the plug core. It is equipped with the locking steel ball on the plug to give up the throne. Be equipped with the sealing washer on the plug core. Beneficial effect: reliable, the easy processing of simple structure has improved efficiency and security, adopts unique ball formula locking structure, and messenger's locking steel ball matches with the plug of giving up the throne, and in tightening the plug of giving up the throne for thick liquid in -process locking steel ball, after bumping the pressure, the locking steel ball pops out inslot, sealed auto -lock and prevent the cement the well grout backward flow of card at the auto -lock seal receptacle to stop to stay the emergence of cement stopper phenomenon, improve the grout and replace efficiency and cementing quality.
Description
Technical field
The utility model relates to a kind of bruising device, particularly a kind of Novel self-lock bruising device.
Background technology
At present, self-locking bruising device is that Oil/gas Well is solid, a kind of instrument conventional in completion practice, safety in float collar float plug well cementation can be increased, be mainly used in replacing liquid in well, and realize self-locking, the Self-locking rubber cork of conventional self-locking bruising device is all generally carry out self-locking with opening pawl ring, when Self-locking rubber cork enters lock, opening pawl is easily out of shape, Self-locking rubber cork and lock are misaligned, thus likely cause seal failure between Self-locking rubber cork and lock, often there are some seepages, the problem such as poorly sealed, thus reduction cementing quality, add well cementation risk and later stage homework burden.
Summary of the invention
The purpose of this utility model is to solve the seepage that existing self-locking bruising device in use often occurs, poorly sealed problem and a kind of Novel self-lock bruising device provided.
The Novel self-lock bruising device that the utility model provides includes self-locking seal seat, self-locking fuse, plug of giving up the throne, plug fuse and plug glue bowl, wherein self-locking fuse, plug of giving up the throne, plug fuse and plug glue bowl are installed in the inner chamber of self-locking seal seat, before self-locking fuse is arranged on, plug fuse is connected with self-locking fuse by plug of giving up the throne, and plug glue bowl is set on plug fuse.
Plug of giving up the throne is provided with locking steel ball.
Plug fuse is provided with sealing ring.
Operating principle of the present utility model:
Self-locking seal seat is placed in pipe string lower to design choke position, tighten giving up the throne in plug in well cementation for locking steel ball in slurry process, pressing down Self-locking rubber cork with displacement fluid makes it descending, after self-locking fuse and self-locking seal seated connection are touched and are pressed, the card release of locking bomb with steel balls is in the groove of self-locking seal seat, realize self-locking, thus play the effect of unidirectional choked flow.
The beneficial effects of the utility model:
Simple and reliable for structure, easily process, improve efficiency and safety, adopt unique ball locking mechanism, locking steel ball being matched with plug of giving up the throne, tightening giving up the throne in plug, when after bruising for locking steel ball in slurry process, the card release of locking bomb with steel balls is in the groove of self-locking seal seat, sealing self-locking also prevents cementing slurry from refluxing, thus stops the generation staying cement plug phenomenon, improves displacement efficiency of cement slurry and cementing quality.

1, self-locking seal seat 2, self-locking fuse 3, plug 4 of giving up the throne, plug fuse
5, plug glue bowl 6, inner chamber 7, locking steel ball 8, sealing ring.
Detailed description of the invention
Refer to shown in Fig. 1 and Fig. 2:
The Novel self-lock bruising device that the utility model provides includes self-locking seal seat 1, self-locking fuse 2, plug 3 of giving up the throne, plug fuse 4 and plug glue bowl 5, wherein self-locking fuse 2, plug 3 of giving up the throne, plug fuse 4 and plug glue bowl 5 are installed in the inner chamber 6 of self-locking seal seat 1, before self-locking fuse 2 is arranged on, plug fuse 4 is connected with self-locking fuse 2 by plug 3 of giving up the throne, and plug glue bowl 5 is set on plug fuse 4.
Plug 3 of giving up the throne is provided with locking steel ball 7.
Plug fuse 4 is provided with sealing ring 8.
Operating principle of the present utility model:
Self-locking seal seat 1 is placed in pipe string lower to design choke position, tighten giving up the throne in plug 3 in well cementation for locking steel ball 7 in slurry process, pressing down Self-locking rubber cork with displacement fluid makes it descending, after self-locking fuse 2 contacts bruising with self-locking seal seat 1, locking steel ball 7 ejecting card is in the groove of self-locking seal seat 1, realize self-locking, thus play the effect of unidirectional choked flow.
