Embodiment
The utility model is described further below in conjunction with accompanying drawing：
The present embodiment includes top connection 1, lower contact 5, central tube 7, setting mechanism, solution sealing mechanism and packing element component, above connects
First 1 and lower contact 5 be separately positioned on the upper and lower ends of packer, central tube 7 is through the center of packer, packing element component suit
At the middle part of central tube 7, setting mechanism is arranged between packing element component and lower contact 5, solution sealing mechanism be arranged on packing element component with
It is provided between top connection 1, in setting mechanism and sets piston 6, is suppressed to promote into central tube 7 and set piston 6 to close to glue
The direction motion of cartridge module, then compresses packing element 4, swells the outer wall of packing element 4, realize setting for packer.Above to be existing
Conventional structure in technology, will not be repeated here.
Sealing mechanism is solved, including cylinder 2, Cut Block 13, lock sleeve 3 and lock body 10, the upper end of cylinder 2 are connected through a screw thread
In top connection 1, the lower end of cylinder 2 is connected by screw thread with the upper end of lock sleeve 3, and the side of the lower end of lock sleeve 3 is provided with
Spacer pin 9, lock body 10 is moved close to the direction of top connection 1 in the same direction in the presence of spacer pin 9 with lock sleeve 3 one, described
Lock claw 14 is distributed with the upper end edge even circumferential of lock body 10, and described Cut Block 13 is cut between cylinder 2 and central tube 7
Cut seat 13 to be threadedly attached on central tube 7, deblocking pin 12 is installed on cylinder 2, the end of deblocking pin 12, which is inserted in, cuts
Cut in the annular groove on seat 13.During deblocking, upper lifting pipe post, deblocking pin 12 is cut first, but is cut wink in deblocking pin 12
Between, packing element 4 does not unseal, the release glue but the lock claw 14 that moves up behind a section in lock body 10 of lock sleeve 3 just unlocks
Cylinder 4, therefore, when deblocking pin 12 is cut, above put forward deblocking power and act only on the deblocking pin 12 on single packer, without
Act on simultaneously on multiple-string packer.That is, each packer on tubing string from top to bottom gradually deblocking, is sealed in the absence of multistage
Every the deblocking pin 12 of device while the situation of stress, occur above proposing deblocking so as to avoid conventional packer because series is excessive
The problem of power is excessive.
