Detailed description of the invention
The hanger running tool that this linkage is given up includes central canal 1, top connection 2, lower contact 3, piston 4, cylinder sleeve 5, slips 6, setting sleeve 7 and spring housing 8.The threaded one end of central canal 1 is provided with top connection 2, and the other end screw thread of central canal 1 is provided with lower contact 3;Fixed by interior hexagonal holding screw 9 respectively between central canal 1 and top connection 2 and lower contact 3.Equipped with crossing cam bit 10 on the central canal 1 of top connection 2 side, equipped with elastic claw 11 on cam bit 10.Being radially arranged installing hole on elastic claw 11, elastic claw 11 is arranged on cam bit 10 by installing hole.
By cylinder sleeve 5, piston 4 is installed on central canal 1 between elastic claw 11 and top connection 2, threadeds between cylinder sleeve 5 with top connection 2, fix between cylinder sleeve 5 and top connection 2 and by interior hexagonal holding screw 9.Piston 4 side is provided with between piston extending sleeve 12 piston extending sleeve 12 and central canal 1 and is connected fixing by setting pin 13.Equipped with setting sleeve 7 on piston extending sleeve 12, it is connected fixing between piston extending sleeve 12 with setting sleeve 7 by pin 14 of giving up.
Piston extending sleeve 12 one end is provided with draw-in groove 15, and the termination of elastic claw 11 is provided with protruding 16, and elastic claw 11 is slidably connected with piston extending sleeve 12 with coordinating of draw-in groove 15 by protruding 16.
By slip sleeve 17 equipped with slips 6 on the central canal 1 of lower contact 3 side, being provided with oblique piece 18 between slips 6 and central canal 1, oblique piece 18 is slidably connected with slips 6.It is connected fixing between oblique piece 18 with slip sleeve 17 by shear pin A19;It is connected fixing between slip sleeve 17 with lower contact 3 by interior hexagonal holding screw 9.
Shoulder it is provided with, equipped with ejector sleeve 20 on the central canal 1 of shoulder side on the central canal 1 of slips 6 side;By shear pin B21 equipped with spring housing 8 on central canal 1 between ejector sleeve 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, equipped with spring 24 on the spring housing 8 between gear 23 and nut 22;
Central canal 1 outer surface of shear pin B21 side is provided with ratchet.
The hanger running tool that this linkage is given up can be divided into setting mechanism, anchor mechanism and three parts of releasing gadget by its function.
Setting mechanism is made up of top connection 2, piston 4, cylinder sleeve 5, piston extending sleeve 12, central canal 1, setting sleeve 7, elastic claw 11 and cam bit 10.
Anchor mechanism is made up of central canal 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, when assembling, is first contained on slip sleeve 17, then loads oblique piece 18 from right-hand member by the anchor mechanism of the hanger running tool that this linkage is given up;The dovetail groove of oblique piece 18 matches with slips 6, reinstalls shear pin A19, and the 45 ° of phase places that misplaced with slips 6 respectively by 4 boss of ejector sleeve 20 load.
Gear 23 is when assembling, first gear 23 is enclosed within spring housing 8, cubic flat position outer with spring housing 8, the flat position, interior four directions of gear 23 coordinates, and in spring housing 8, cubic flat position outer with central canal 1, cubic flat position coordinates, and makes gear 23, spring housing 8, central canal 1 can only produce axial displacement each other.
During work, first this running tool is connected with packer, then by drilling rod/tubing transmission, is lowered into precalculated position.This running tool can connect ball seat bottom tubing string and build the pressure, it is possible to utilize the direct pitching of the ball seat on central canal 1 to build the pressure.
When this running tool enters well, slips 6 is connected the main suspension of formation with packer sealing cylinder, cam bit 10 forms assisted suspension with packer setting set, owing to elastic claw 11 is pushed down by setting sleeve 7, only cut off setting sleeve 7 after setting pin 13 just can be subjected to displacement by hydraulic action, setting sleeve 7 just can be subjected to displacement rear elastic claw 11 just activity space, packer just can start and sets, thus can prevent packer from causing its premature setting during entering well.
This running tool enters well to behind precalculated position, puts into the ball of suitable dimension from oil pipe, pressurizes from oil pipe after ball is taken a seat.When the pressure reaches a predetermined value, piston 4 moves down, and the shear pin on setting tool is cut off, and piston extending sleeve 12 promotes elastic claw 11 to move down, cam bit 10 falls after rise after running into the necking down of central canal 1, now elastic claw 11 pushes spring housing 8 and moves down, compression spring 24, and outer four square grooves of spring housing 8 depart from four directions in gears 23, moment of torsion discharges, piston 4 produces downward mechanical thrust, and then promotes packer setting, is achieved in setting.
After testing seal about packer completes, continue to be pumped to packer oil pipe, after reaching certain force value, piston extending sleeve 12 cuts off pin 14 of giving up, and stress moves down, and drives spring housing 8, ejector sleeve 20 to move down, boss on ejector sleeve 20 pushes oblique piece 18 and moves down, 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 square groove, and oblique piece 18 realizes linkage with slips 6 by dovetail groove and reach function of giving up.
Owing to central canal 1 the latter half is provided with cubic flat position, there is flat position, corresponding four directions matched respectively on ejector sleeve 20 and oblique piece 18, under hydraulic thrust effect, ejector sleeve 20, oblique piece 18 can be axially moveable, without there is radial rotary, misoperation is not had, it is ensured that action of giving up is safe and reliable when making to give up.
In emergency circumstances, can realize giving up by dextrorotation tubing string.Top connection 2 is threadeded with central canal 1, and central canal 1 is threadeded with lower contact 3, and lower contact 3 is threadeded with slip sleeve 17, slips 6 is attached separately in slip sleeve 17 window, setting tool entirety dextrorotation, slips 6 screw thread departs from packer sealing cylinder screw thread, successfully gives up.
