It is fixed；It is connected between slip sleeve 17 and lower contact 3 by interior hexagonal holding screw 9.
Shoulder is provided with the central tube 1 of the side of slips 6, ejector sleeve 20 is housed on the central tube 1 of shoulder side；Ejector sleeve
Spring housing 8 is equipped with by shear pin B21 on central tube 1 between 20 and cam bit 10, the threaded one end of spring housing 8 is provided with
Nut 22, the other end termination of spring housing 8 is provided with gear 23 by chuck, on the spring housing 8 between gear 23 and nut 22
Equipped with spring 24；
The outer surface of central tube 1 of shear pin B21 sides is provided with ratchet.
The hanger running tool that the linkage is given up can be divided into setting mechanism, anchor mechanism and releasing gadget three by its function
Individual part.
Setting mechanism is by top connection 2, piston 4, cylinder sleeve 5, piston extending sleeve 12, central tube 1, setting sleeve 7, the and of elastic claw 11
Cam bit 10 is formed.
Anchor mechanism is made up of central tube 1, ejector sleeve 20, slips 6, slip sleeve 17, lower contact 3 and oblique piece 18.
Releasing gadget is made up of nut 22, spring 24, spring housing 8, gear 23, slips 6 and oblique piece 18.
Slips 6 is mounted in slip sleeve 17 by the anchor mechanism for the hanger running tool that the linkage is given up first in assembling
On, then load oblique piece 18 from right-hand member；Oblique piece 18 of dovetail groove is engaged with slips 6, is reloaded into shear pin A19, and
Misplaced respectively with slips 6 45 ° of phases of 4 boss of ejector sleeve 20 are loaded.
Gear 23 is enclosed on spring housing 8 by gear 23 first in assembling, the interior flat position in four directions and the spring housing 8 of gear 23
The outer flat position in four directions coordinates, and the flat position in four directions coordinates with the outer flat position in four directions of central tube 1 in spring housing 8, makes gear 23, spring housing 8, center
Pipe 1 can only produce axial displacement each other.
The running tool is connected with packer first during work, then by drilling rod/tubing transmission, is lowered into precalculated position.
The running tool can connect ball seat in tubing string bottom and build the pressure, and the direct pitching of the ball seat on central tube 1 can also be used and build the pressure.
Slips 6 is connected to form main suspension with packer sealing cylinder when the running tool enters well, and cam bit 10 is sat with packer
Big envelope forms assisted suspension, because elastic claw 11 is pushed down by setting sleeve 7, is only cut by hydraulic action and sets the recoil of pin 13
Big envelope 7 can be just subjected to displacement, and setting sleeve 7, which can just be subjected to displacement rear elastic claw 11, just activity space, and packer can just start seat
Envelope, so as to prevent packer from causing its premature setting during well is entered.
The running tool enters well to behind precalculated position, from the ball of oil pipe input suitable dimension, adds after ball is taken a seat from oil pipe
Pressure.When the pressure reaches a predetermined value, piston 4 is moved down, and the shear pin on setting tool is cut, and piston extending sleeve 12 promotes
Elastic claw 11 moves down, and cam bit 10 falls after rise after running into the necking down of central tube 1, and now it is downward to push spring housing 8 for elastic claw 11
Mobile, compression spring 24, outer four square grooves of spring housing 8 depart from four directions in gear 23, moment of torsion release, and piston 4 produces downward machinery
Thrust, and then packer setting is promoted, it is achieved in setting.
After the completion of testing seal about packer, continue to be pumped to packer oil pipe, after reaching certain pressure value, piston extending sleeve 12
Cutting is given up pin 14, and stress moves down, and drives spring housing 8, ejector sleeve 20 to move down, the boss on ejector sleeve 20 pushes
Move down for oblique piece 18, the dovetail groove on oblique piece 18 falls after rise with the dovetail on slips 6, and 4 slips 6 just fall at oblique piece 18
In prescription groove, realized for oblique piece 18 and linked to reach function of giving up by dovetail groove with slips 6.
Because the latter half of central tube 1 is provided with the flat position in four directions, there are corresponding four respectively on ejector sleeve 20 and oblique piece 18
The flat position in side is matched, under hydraulic thrust effect, ejector sleeve 20, oblique piece 18 can be axially moveable, without footpath occurs
Be not in malfunction when making to give up to rotation, guarantee gives up action securely and reliably.
In emergency circumstances, it can be realized and given up by dextrorotation tubing string.Top connection 2 is threadedly coupled with central tube 1, central tube 1 with
Lower contact 3 is threadedly coupled, and lower contact 3 is threadedly coupled with slip sleeve 17, and slips 6 is attached separately in the window of slip sleeve 17, sets work
Has overall dextrorotation, the screw thread of slips 6 departs from packer sealing cylinder screw thread, successfully given up.
