Detailed description of the invention
This double acting give up hydraulic setting tool by central canal 1, top connection 2, piston 3, piston bush 11, elastic claw 4, set
Set 5, seal nipple 6, mandrel 7, gear 8, release ring 9, slips 10 and slips sheath 12 are constituted；The threaded one end peace of central canal 1
Equipped with top connection 2, top connection 2 is connected with central canal 1 by holding screw 32.The other end of central canal 1 is threaded have close
Sealing joint 6, the periphery of seal nipple 6 is spaced shape and is provided with seal assembly 34, be provided with spacer ring 35 between seal assembly 34.
The purpose arranging seal assembly 34 is: seal packer 39.
The threaded one end of seal nipple 6 is provided with lower contact 14.Central canal 1 is by by holding screw 32 and seal nipple
6 are connected, and seal nipple 6 is connected with lower contact 14 by holding screw 32.Bullet is passed through between seal nipple 6 and top connection 2
Property pawl 4 be movably installed with cam bit 15, during when the conveying of this setting tool, packer 39 goes into the well, cam bit 15 and packer 39
Conflict and connect, in order to prevent packer 39 premature setting under the effect of external force (seeing Figure of description 1).
Piston bush 11 is passed through equipped with piston 3 and shear sleeve 16 in elastic claw 4 side；Piston 3 is fitted and connected with shear sleeve 16.Cut
Cut and be connected by shear pin B33 between set 16 and central canal 1.Threaded between piston bush 11 with top connection 2, piston bush
11 are connected by holding screw 32 is fixing with top connection 2.By shear pin A17 equipped with setting sleeve 5 on shear sleeve 16.
Elastic claw 4 opposite side is by shear pin C18 equipped with mandrel 7, and the threaded one end of mandrel 7 is provided with baffle ring A19, gear
Being provided with lock ring 20 between ring A19 and mandrel 7, lock ring 20 is C-shaped ring, and the internal ring of lock ring 20 is provided with unidirectional ratchet, lock ring
20 are threadeded with central canal 1 by unidirectional ratchet.The purpose arranging lock ring 20 is: guarantees mandrel 7 single-way moving, prevents core
Axle 7 reversely moves back.
The other end of mandrel 7 is by compression spring 21 equipped with gear 8, and gear 8 side is by discharging ring 9 equipped with slips sheath
12, slips sheath 12 is connected with release ring 9 by shear pin F13.The window of slips sheath 12 is embedded with slips 10.Release
Put interval shape on the periphery of ring 9 and be provided with release annular groove.
It is connected by holding screw 32 between slips sheath 12 with seal nipple 6.During work, this setting tool is by card
Watts 10 threaded with packer 39.It is provided with flat spring 22, the slips sheath of slips 10 side between slips 10 and release ring 9
It is equipped with locating ring 24, the purpose arranging locating ring 24 by shear pin D23 on 12: packer 39 is carried out spacing.
Equipped with standby ball seat 25 inside one end of central canal 1；Pressurizing port A36, pressurizing port A36 it is provided with on standby ball seat 25
It is provided with pressurizing port B37 on the central canal 1 of side.By bypass set 26 screw threads, baffle ring B30, baffle ring are installed in lower contact 14
B30 is in order to carry out spacing to bypass set 26 and ball seat 28.By shear pin E27 equipped with ball seat 28, ball seat 28 in bypass set 26
It is respectively arranged with material ball 38 with in standby ball seat 25.Needs when, in ball seat 28 and standby ball seat 25, put into material
After ball 38, material ball 38 can be sealed against.It is provided with retaining ring 29 between ball seat 28 and bypass set 26.Retaining ring 29 is C-shaped ring,
It is provided with by-pass prot 31 on bypass set 26.
This double acting gives up hydraulic setting tool work when making packer 39 set, it is necessary first to pitching in central canal 1,
Make material ball 38 fall on ball seat 28, ball seat 28 is shut.And backward this setting tool is suppressed, after this setting tool pressurized, pressure
Power will press by giving piston 3 after pressurizing port A36 and pressurizing port B37.After piston 3 pressurized, promotion shear sleeve 16 is cut off shear pin
Moving down after nail B33, shear sleeve 16 is in folding process, and shear sleeve 16 can drive setting sleeve 5 squeeze packer 39.Packer
Can realize after 39 pressurizeds setting.Can stop mobile with back piston 3.In the above process, can be to extruding bullet when shear sleeve 16 moves
Property pawl 4, cam bit 15 can be driven to move down after elastic claw 4 pressurized, when piston 3 stops mobile, cam bit 15 can lose
Support also disengages (seeing Figure of description 5) with packer 39.
After packer 39 has set, when needing to give up, need to continue to suppress to this setting tool, meeting after piston 3 pressurized
Continuing through shear sleeve 16 and packer 39 is pressed by setting sleeve 5, under the counteracting force of packer 39, piston 3 can promote and cut
Cut set 16 to cut off shear pin A17 pusher dynamic elasticity pawl 4 and move down.Elastic claw 4 can be pushed away by baffle ring A19 in moving process
Moving mandrel 7 moves down, and moves down after promotion release ring 9 being cut off shear pin F13 in mandrel 7 moving process.Work as release
Stop mobile when ring 9 and seal nipple 6 are conflicted.Now slips 10 can misplace with release ring 9, and contacts, now with release annular groove
Slips 10 can lose the support of release ring 9.Slips 10 loses after support under the effect of flat spring 22, and slips 10 can shrink and envelope
Disengage every device 39, thus realize giving up.
In order to it taken out from shaft bottom smoothly after this hydraulic setting tool is given up, need to continue to suppress.Work as pressure
When power reaches certain size, material ball 38 can promote ball seat 28 to move downward after cutting off shear pin E27, when ball seat 28 moves
When contacting to conflicting with baffle ring B30, ball seat 28 stop motion, now retaining ring 29 can be conflicted with the end face of bypass set 26 and is connected.
When ball seat 28 moves to bottom, by-pass prot 31 and ft connection can be passed through in the inside of this setting tool, so that this hydraulic pressure is sat
The external and internal pressure of envelope instrument reaches balance, and then facilitates the recovery (seeing Figure of description 7) of setting tool.
This double acting hydraulic setting tool of giving up needs action to realize when promptly giving up, and only needs dextrorotation tubing string, at dextrorotation pipe
During post, tubing string can pass through top connection 2, central canal 1 and seal nipple 6 and drive slips sheath 12 to rotate.Slips sheath 12 is rotating
During slips 10 can be driven to rotate together, the most just slips 10 can be unclamped with packer 39, it is achieved promptly give up.
In practical work process, after packer 39 sets, if the setting force that is subject to of packer 39 is inadequate, can be to
Pitching again in central canal 1, makes material ball 38 fall on standby ball seat 25, and this setting tool backward is suppressed, and pressure can pass through
Again press to after pressurizing port A36 and pressurizing port B37 piston 3, thus increase setting force.
This double acting is given up hydraulic setting tool simple in construction, easy to use, and solve that existing setting tool has lacks
Weary function and the problem of difficulty of giving up of promptly giving up, meets the needs of enterprise's production and application.
