Specific embodiment
The present invention is described further below in conjunction with attached drawing:
The present embodiment includes lubricator 13, test plug 14 and guide wheel 15, and test plug 14 is threadedly attached in blowout prevention
The upper end of pipe 13, guide wheel 15 are mounted on the side of 13 upper end of lubricator by bracket.The above are common structure in the prior art,
Details are not described herein.
Main innovation point of the invention is to further include end matched with test plug 14.In order to salvage conveniently, instrument
The upper end of device is respectively connected with salvageable end, but is absolutely fixedly connected between existing cable head and test cable 9,
After impact test plug 14, only test cable 9 is pulled off a kind of as a result, and the breaking point of test cable 9 is uncertain.
And the present invention devises a kind of novel end, in 8 impact test plug 14 of instrument, suspension body 16 is first by Anti-slip cover 3
Spring detent B7 hook, achieve the purpose that prevent instrument 8 from falling, instrument 8 continue uplink after, the lower end of the mandril 4 and cone
The upper end of set 17 is hit, and tapered sleeve 17 overcomes stiction downlink, to release the clamping action to test cable 9, test cable 9
Deviate from out of tapered sleeve 17, to achieve the purpose that prevent test cable 9 disconnected de-.By preventing test cable 9 disconnected de-, that is, can avoid
The meaningless loss of test cable 9, and the non-cutting time of well logging has been saved, improve operating efficiency.
The structure of the test plug includes silk plug 1, mounting body 2, Anti-slip cover 3, mandril 4 and sliding sleeve 5, the peace
Dress main body 2 is threadedly attached in the bottom of silk plug 1, and the lower end of mounting body 2 is provided with spring detent A6, the mandril 4
Upper end is threadedly attached in mounting body 2, and the Anti-slip cover 3 is arranged in mounting body 2, and the upper end of Anti-slip cover 3 is inserted
In annular space between mounting body 2 and mandril 4, being provided between the upper end and mounting body 2 of Anti-slip cover 3 can make to prevent
Press-off the 3 spring A10 for keeping down movement tendency, and the lower end of Anti-slip cover 3 is provided with spring detent B7, is against on the outside of spring detent B7
The inside of spring detent A6 has been provided with the hook 12 of anti-lost effect on the outside of spring detent B7, and the upper end of the end is stuck in
On hook 12, thus realize anti-lost function, 5 sets of the sliding sleeve outsides in the mounting body 2, the lower end position of sliding sleeve 5
It is provided with and can make between the outside of spring detent A6 moving radially with limited spring pawl A6, the upper end and silk plug 1 of sliding sleeve 5
Sliding sleeve 5 keeps down the spring B 11 of movement tendency.
The structure of the end includes suspension body 16, tapered sleeve 17, spring C18 and pressure cap 19, and tapered sleeve 17 is inserted into outstanding
In hanging body 16, pressure cap 19 is threadedly attached in the bottom of suspension body 16, and spring C18 is arranged between pressure cap 19 and tapered sleeve 17,
To the movement tendency that makes tapered sleeve 17 keep up, the side setting of tapered sleeve 17 makes tapered sleeve 17 can be to there are four axial cut-outs 20
Center is gathered, to clamp test cable 9, the upper end of tapered sleeve 17 is higher than the upper end of suspension body 16.When it is implemented, in tapered sleeve 17
Setting slip-resistant texture to be on the upper face being bonded with test cable 9 to increase frictional force, is applied by spring C18 to tapered sleeve 17 certain
Pretightning force makes the inner surface of tapered sleeve 17 keep being bonded with test cable 9, and the frictional force between tapered sleeve 17 and test cable 9 is greater than
Frictional force between tapered sleeve and suspension body 16, therefore, when being pulled up test cable 9, tapered sleeve 17 is upward together with test cable
Movement, so that tractive force is bigger, tapered sleeve 17 is bigger to the clamping force of test cable 9, so that test cable 9 is securely attached at
On end.
Working principle of the present invention is as follows:
1, anti-lost: 14 moment of end impact test plug, the suspension body 16 on end withstand Anti-slip cover 3 upwards and make
Its uplink, with the uplink of Anti-slip cover 3, spring detent A6 releases the position-limiting action of spring detent B7, and spring detent A radially expands
, to enable the flange on suspension body to cross hook 12, into the inside of spring detent B7, at this point, if end is i.e. by bullet
Spring pawl B is hooked, and realizes anti-lost purpose.
2, fast de-: upward sliding sliding sleeve 5, the limit on the outside of spring detent A6 release, and then pull out end, spring detent B7 downwards
It expands outwardly spring detent A6 under the guidance on inclined-plane, then extracts Anti-slip cover 3 out of mounting body 2, finally by Anti-slip cover 3
Separating with end can quickly remove end.
3, test cable 9 is prevented to be pulled off: when the end and test plug 14 for being connected to 8 upper end of instrument are hit, cable
Head continues uplink after being hooked, the lower end of mandril 4 and the upper end of tapered sleeve 17 are hit, and tapered sleeve 17 overcomes stiction downlink, thus
The clamping action to test cable 9 is released, test cable 9 is deviate from out of tapered sleeve 17, in this case, test cable 9 and instrument 8
Between connecting part can be broken, and test cable 9 itself will not be broken, to achieve the purpose that prevent test cable 9 disconnected de-.
Difference in height between the upper end of the tapered sleeve 17 and the upper end of suspension body 16 is not less than 3mm, to guarantee tapered sleeve 20
It is sufficiently disengaged from test cable 9.
