Abstract
The invention discloses a kind of reversible bridging plug, include a body, one end of body is provided with a pipe sleeve, is connected between pipe sleeve and body by an elastic, and the end of pipe sleeve is provided with primary antibody pressure cap, resistance to compression cap and pipe sleeve are integrally formed, the other end of body is socketed a block rubber, and the side of block rubber is provided with a fixing threaded hole, multiple pores are provided near fixing threaded hole, the end of block rubber is provided with a spring support, and spring support is provided with a shank.The reversible bridging plug of the present invention is provided with a sleeve pipe for carrying antivibration cap in one end of bridging plug body, and antivibration cap is elastic protection device, body can be protected to be stressed directly when bridging plug end is by impact.The block rubber that the other end of bridging plug body is set mainly shields to the side of bridging plug, and such bridging plug side power that is hit will not rupture, so as to effectively extend the service life of bridging plug.
Description
Technical field
The present invention relates to a kind of bridging plug, more precisely, being a kind of reversible bridging plug.
Background technology
The effect of bridging plug is Oil/gas Well sealing, has the characteristics of working procedure is few, the cycle is short, card envelope position is accurate, is divided into
Two kinds of permanent type bridging plug and reversible bridging plug.Reversible bridging plug is one kind of bridging plug, the reversible bridging plug being commonly used
Resistance to shock is weaker, easy fragmentation when body is by larger external impacts, influences the service life of bridging plug.
The content of the invention
The present invention mainly solves the technical problem present in prior art, so as to provide a kind of reversible bridging plug.
The above-mentioned technical problem of the present invention is mainly what is be addressed by following technical proposals：
A kind of reversible bridging plug, comprising a body, one end of body is provided with a pipe sleeve, is connected between pipe sleeve and body by an elastic
Connect, the end of pipe sleeve is provided with primary antibody pressure cap, and resistance to compression cap and pipe sleeve are integrally formed, and the other end of body is socketed a block rubber, rubber
The side of block is provided with a fixing threaded hole, and multiple pores are provided near fixing threaded hole, and the end of block rubber is provided with a spring support, bullet
Property seat is provided with a shank.
As preferred embodiments of the present invention, described shank and spring support are integrally formed.
As preferred embodiments of the present invention, the quantity of described pore is no less than 2.
The reversible bridging plug of the present invention is provided with a sleeve pipe for carrying antivibration cap in one end of bridging plug body, and antivibration cap is
Elastic protection device, body can be protected to be stressed directly when bridging plug end is by impact.The other end of bridging plug body is set
The block rubber put mainly shields to the side of bridging plug, and such bridging plug side power that is hit will not rupture, so as to effectively prolong
The service life of bridging plug is grown.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the required accompanying drawing used in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the dimensional structure diagram of the reversible bridging plug of the present invention.
Embodiment
The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
As shown in figure 1, a kind of reversible bridging plug 1, comprising a body 10, one end of body 10 is provided with a pipe sleeve 20, pipe sleeve
Connected between 20 and body 10 by an elastic 22, the end of pipe sleeve 20 is provided with primary antibody pressure cap 21, resistance to compression cap 21 and pipe sleeve 20 1
Body formed, the other end of body 10 is socketed a block rubber 30, and the side of block rubber 30 is provided with a fixing threaded hole 31, fixing threaded hole 31
Near be provided with multiple pores 32, the end of block rubber 30 is provided with a spring support 41, and spring support 41 is provided with a shank 40.
It is integrally formed as to further improvement of the present invention, described shank 40 and spring support 41.
2 are no less than as the quantity to further improvement of the present invention, described pore 32.
The reversible bridging plug of the invention is provided with a sleeve pipe for carrying antivibration cap in one end of bridging plug body, and antivibration cap is
Elastic protection device, body can be protected to be stressed directly when bridging plug end is by impact.The other end of bridging plug body is set
The block rubber put mainly shields to the side of bridging plug, and such bridging plug side power that is hit will not rupture, so as to effectively prolong
The service life of bridging plug is grown.
Only illustrate the mentality of designing of the present invention in one embodiment above, in the case where system allows, the present invention can
To expand to while external more functional modules, so as to extend its function to greatest extent.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
The change or replacement expected without creative work, it should all be included within the scope of the present invention.Therefore, it is of the invention
Protection domain should be determined by the scope of protection defined in the claims.
