Operation principle:
1st, it is setting:Top connection 1 is connected by this blanking plug input underground by the steel wire rope of winch wire on well, packing is reached
Steel wire rope is above carried during suitable position in device, first, each cam 30 of Cam set assembly 26, which is downwardly turned over, opens and dragged for head 33
Block will not resilience, cam 30, which is stuck in packer, makes main body up, drive slip spider 10, lower joint sleeve 8, adapter sleeve 7,
Upper joint sleeve 6 can not be up.Top connection 1 is up by sliding sleeve 3, steel ball 13, the drive of adjustment cap 4 intermediate sleeve 5, and intermediate sleeve 5 passes through
Screw 29 drives tapered sleeve overcoat sheath 96 up, up by the drive packing element inner sheath 93 of sliding pin 20, and tapered sleeve sheath 95 is opened, glue
92 compressed expansion blockages of cylinder live packer endoporus.Packing element inner sheath 93 is up to drive the up limitation to each slips 11 of push rod 24
Effect is released, and each slips 11 is opened along the upward sliding of slip spider 10 under the compression of stage clip 3 25 and is stuck in packer endoporus
Interior, slips 11 withstands packing element inner sheath 93 by push rod 25 makes packing element 92 not bounce back.Lock tube 19 during intermediate sleeve 5 is up
On unidirectional teeth be mutually engaged with the unidirectional teeth on the outer wall of intermediate sleeve 5, the lower end that the lower end of lock tube 19 is connected set 7 is pinned and made
Intermediate sleeve 5 will not bounce back, and packing process terminates.It is engaged when sliding sleeve 3 rises to steel ball 13 with dragging for the section of the upper undergauge on bar 2 21
When, steel ball 13 is released to the axial direction connection between sliding sleeve 3 and adjustment cap 4, and sliding sleeve 3 is disengaged from adjustment cap 4, top connection 1 and cunning
Set 3 can be mentioned on well by steel wire rope.
Deblocking:Special fishing tool is put into underground by winch wire from well and pushes overcoat 27 and bearing pin sheath
15th, compression press spring 1 and bar 2 is dragged for.When overcoat 27 slip down to pin shaft hole thereon it is relative with each position of bearing pin 14 when, respectively
Bearing pin 14 is skidded off from overcoat 27 to be come off, and the effect that axially confines that intermediate sleeve 5 drags for undergauge section 22 in bar 2 by each 14 pairs of bearing pin is solved
Remove, it is possible to upper bailing bar 2, lower undergauge section 23 thereon and the cunning between intermediate sleeve 5 and packing element assembly 9 are up to when dragging for bar 2
When the position of pin 20 is relative, sliding pin 20 is inside contracted, and axially confine effect of the intermediate sleeve 5 to packing element assembly 9 is released, and packing element 92 bounces back simultaneously
Each slips 11 is pushed by push rod 24 to glide on slip spider 10, each slips 11 releases the restriction effect of blanking plug.Drag on bar 2
While row, the position-limiting action for dragging for each cam 30 of 33 pairs of head for dragging for the bottom of bar 2 is released, and each cam 30 is in cam torsion spring 32
Downwardly turned under effect, the locking action of cam 30 is released, bailing bar 2 in continuation, drag for dragging for head 33 and can just blocking for the lower end of bar 2
Firmly the lower surface of slip spider 10, so as to which whole blanking plug is proposed from underground, completes deblocking process.
