Abstract
The utility model discloses a kind of expansion pipe hanger, it comprise lower contact, ball seat, swollen plug cradle, swollen plug, left-hand thread are given up, adapter sleeve of giving up, C type anchor ring, cartridge, expansion tube, connecting rod, stop collar, shear pin, expansion tube adapter sleeve, torsion pass joint.Swollen wall is beyond the Great Wall expanding gradually from top to bottom, has evaded bit freezing risk while the effective swollen envelope expansion tube of this design.And design permission of the present utility model two kinds of modes of giving up, one is that conventional hydraulic is given up, and automatically puts aside after swollen envelope completes, and one is emergent giving up, and gives up once the rotatable machinery of card met by expand tube, can assurance function and safety.In addition, expansion tube sets the C type anchor ring devising the band anchor tooth extended out with type of structure innovation, strengthens anchoring ability.
Description
Technical field
The utility model relates to drilling liner cementing completion technique field, especially a kind of expansion pipe hanger.
Background technology
Expansion tube is mainly used in casing failure subsidy technology and sidetracked hole completion technique field.Inflatable sleeves Manifold technology really realizes the single hole diameter oil well shaft building from well head to target zone, significantly can reduce drilling cost, have again good environment protecting.In addition, in sidetracked hole, also have potential benefit through milling window expander mounting tube, reduce the cost heavily bored, make the internal diameter loss reduction of casing string, target zone well is larger.
Extension hanger is the core tool realizing drilling liner cementing, extension hanger and tail pipe are contacted and are connect, by running tool, extension hanger and tail pipe string are delivered to planned well section, hanger carries out well cementing operation, proposition running tool after completing after sitting in the sleeve pipe of upper strata and hanging.The extensive use but still there are some drawbacks of conventional hanger, usually can not rotate, generally do not possess sealing function, under enter the easy clashing and breaking of slips in process, comparatively outstanding at deep-well, high angle hole and net horizontal section, affect drilling liner cementing quality and success rate.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of expansion pipe hanger.
In order to solve the problems of the technologies described above, the utility model comprises the torsion pass joint be threaded successively from top to bottom, expansion tube adapter sleeve, expansion tube and lower contact, described lower contact inner thread is connected with a ball seat, be threaded above described ball seat swollen plug cradle from down to up successively, to give up adapter sleeve, left-hand thread is given up and connecting rod, described swollen plug cradle and giving up also to be provided with between adapter sleeve one can swollen envelope expansion tube swollen plug and this swollen plug sleeve is contained on swollen plug cradle outer wall, described swollen wall is beyond the Great Wall expanding gradually from top to bottom, described expansion tube adapter sleeve inwall lower end is connected with a stop collar by shear pin and this stop collar is sleeved on connecting rod, described shear pin is sheared that rear stop collar is up can be connected in expansion tube adapter sleeve, described left-hand thread is given up, and upper end and stop collar lower end are also corresponding up and down to be arranged, described expansion tube outer wall is also provided with multiple spaced C type anchor ring and cartridge.
Described left-hand thread gives up outer wall last week to being formed with the flange of a circle for adapter sleeve location and installation of giving up.
The beneficial effects of the utility model are:
1, the utility model expansion pipe hanger exposed parts is few, area of passage large, have the features such as packing function, avoids phenomenons such as sitting extension and part injury in advance, touch off occurs.Bunch tube can be driven in cementing, displacement process to rotate, annular space displacement efficiency, cementing quality can be significantly improved.
2, bit freezing risk has been evaded while the effective swollen envelope expansion tube of the design of swollen plug.
3, design permission of the present utility model two kinds of modes of giving up, one is that conventional hydraulic is given up, and automatically puts aside after swollen envelope completes, and one is emergent giving up, and gives up once the rotatable machinery of card met by expand tube, can assurance function and safety.
4, expansion tube sets the C type anchor ring devising the band anchor tooth extended out with type of structure innovation, strengthens anchoring ability.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model expansion pipe hanger.
Detailed description of the invention
See Fig. 1, expansion pipe hanger of the present utility model comprises the torsion pass joint 14 be threaded successively from top to bottom, expansion tube adapter sleeve 13, expansion tube 9 and lower contact 1, described lower contact 1 inner thread is connected with a ball seat 2, be threaded above described ball seat 2 swollen plug cradle 3 from down to up successively, to give up adapter sleeve 6, left-hand thread is given up 5 and connecting rod 10, described swollen plug cradle 3 and giving up also to be provided with between adapter sleeve 6 one can swollen envelope expansion tube 9 swollen plug 4 and this swollen plug 4 is sleeved on swollen plug cradle 3 outer wall, described swollen plug 4 outer wall is expanding gradually from top to bottom, described expansion tube adapter sleeve 13 inwall lower end is connected with a stop collar 11 by shear pin 12 and this stop collar 11 is sleeved on connecting rod 10, described shear pin 12 is sheared that rear stop collar 11 is up can be connected in expansion tube adapter sleeve 13, described left-hand thread is given up, and 5 upper ends and stop collar 11 lower end are also corresponding up and down to be arranged, described expansion tube 9 outer wall is also provided with multiple spaced C type anchor ring 7 and cartridge 8.Described left-hand thread gave up for 5 outer wall last weeks to being formed with the flange of a circle for adapter sleeve 6 location and installation of giving up.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
The utility model expansion pipe hanger comprises lower contact 1, ball seat 2, swollen plug cradle 3, swollen plug 4, left-hand thread are given up 5, adapter sleeve 6 of giving up, C type anchor ring 7, cartridge 8, expansion tube 9, connecting rod 10, stop collar 11, shear pin 12, expansion tube adapter sleeve 13, torsion pass joint 14.
There is screw buckle corresponding to drilling rod torsion pass joint 14 upper end, torsion pass joint 14 lower end outer wall is threaded expansion tube adapter sleeve 13, expansion tube adapter sleeve 13 lower end is threaded with expansion tube 9, and expansion tube 9 outer wall is designed with multiple cartridge 8 and C type anchor ring 7, C type anchor ring 7 is with anchor tooth can extend out with type.Expansion tube 9 lower end is threaded lower contact 1, the joint screw thread button that the design of lower contact 1 lower end is corresponding with lower tool, lower contact 1 upper end inner thread connection ball seat 2.Torsion pass joint 14 lower end inner wall is threaded with connecting rod 10, connecting rod 10 outer wall cover limited location cover 11, shear pin 12 is designed with between stop collar 11 and expansion tube adapter sleeve 13, connecting rod 10 bottom and left-hand thread are given up and 5 to be threaded, left-hand thread 5 lower ends of giving up are designed with adapter sleeve 6 of giving up, give up adapter sleeve 6 upper end and left-hand thread is given up and 5 to be connected by left hand thread, and adapter sleeve 6 lower end of giving up is connected with swollen plug 4 cradle 3, and swollen plug 4 is fixed on swollen plug 4 cradle 3 outer wall by both.Swollen plug 4 outer wall is expanding gradually from top to bottom, has evaded bit freezing risk while the effective swollen envelope expansion tube 9 of this design.
