The purpose of layer.Country's expandable casing patching technology, bad ground blocking technology reach its maturity at present.But it is applied in long well section expansion tube
In work, due to being typically to push expansion cone tube expansion from bottom to top by fluid power, construction well section is long, and intraluminal fluid column length can cause
Operation pressure is excessively high.If expansion is hampered simultaneously, tool and top rod can not play out well head, cause the accident.
Utility model content：
The technical problem to be solved by the present invention is to provide a kind of expansion tube section construction hydraulic oil cylinder device, which realizes
It can control the expansion cone repeatedly to move and carry out segmentation expansion, segmentation expansion operation pressure is low, reduces construction risk, ensures long well
The safety of section expansion pipe construction, while the tube expansion mode expanded from the top down is taken, well head can be played out at any time, eliminate safety
Hidden danger, securely and reliably, tube expansion length are unrestricted, simple in structure, easy to process, convenience simple to operation.Overcome existing long well
Section expands pipe construction tube expansion from bottom to top, and construction well section is long, causes operation pressure excessively high, while if expansion is hampered, tool
Well head can not be played out with top rod, easily causes the deficiency of accident.
Technical solution adopted in the utility model is：A kind of expansion tube section construction hydraulic oil cylinder device, including top connection；On
Upper locking piece is connected on connector, upper liquid cylinder sleeve seals on the outside of upper locking piece and between upper locking piece, and upper fluid cylinder upper end is with above connecing
Sealed between head, be provided with the upper through-hole of the upper hydraulic cavities between fluid cylinder and upper locking piece of connection in top connection, upper fluid cylinder upper surface with it is upper
Spring is installed, sliding block inner end is embedded in top connection unit with grooves in outer wall, and lower closing piece is stretched into sliding block outer end between connector outer wall step surface
It limits in lateral through aperture and by upper fluid cylinder, the lower fluid cylinder of connection on the outside of lower closing piece, top connection lower end connection center-pole, is opened on center-pole
There is the lower through-hole of hydraulic cavities between connection center-pole and lower fluid cylinder, lower fluid cylinder lower end connects expansion cone, and expansion cone lower end outside is set
There is expansion tube.
It is sealed by sealing ring between upper locking piece and upper fluid cylinder, is sealed between upper fluid cylinder and top connection by sealing ring.
It is sealed between center-pole and lower fluid cylinder by sealing ring.
The beneficial effects of the utility model are：The utility model realizes and expansion cone can be controlled repeatedly to move be segmented
Expansion, segmentation expansion operation pressure it is low, reduce construction risk, ensure long well section expansion pipe construction safety, while take from
On the tube expansion mode that expands downwards, well head can be played out at any time, eliminated safe hidden trouble, securely and reliably, tube expansion length is unrestricted,
It is simple in structure, easy to process, convenience simple to operation.
Description of the drawings：
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structure diagram of the utility model.
Specific embodiment：
As shown in Figure 1, a kind of expansion tube section construction hydraulic oil cylinder device, including top connection 1；Locking is connected in top connection 1
Block 5, upper fluid cylinder 4 are sleeved on 5 outside of upper locking piece and are sealed between upper locking piece 5, sealed between upper 4 upper end of fluid cylinder and top connection 1,
The upper through-hole 12 of the upper hydraulic cavities between fluid cylinder 4 and upper locking piece 5 of connection, upper 4 upper surface of fluid cylinder and top connection 1 are provided in top connection 1
Spring 2 is installed, 6 inner end of sliding block is embedded in 1 unit with grooves in outer wall of top connection, and lower closing piece 7 is stretched into 6 outer end of sliding block between outer wall step surface
It is limited in lateral through aperture and by upper fluid cylinder 4, the lower fluid cylinder 8 of lower 7 outside connection of closing piece, 1 lower end of top connection connection center-pole 9, center
The lower through-hole 13 of hydraulic cavities between connection center-pole 9 and lower fluid cylinder 8 is provided on bar 9, lower 8 lower end of fluid cylinder connects expansion cone 10, swollen
10 lower end outsides of swollen cone are equipped with expansion tube 11.
It is sealed between upper locking piece 5 and upper fluid cylinder 4 by sealing ring 3, it is close by sealing ring 3 between upper fluid cylinder 4 and top connection 1
Envelope.
It is sealed between center-pole 9 and lower fluid cylinder 8 by sealing ring 3.
During tube expansion, drilling fluid is pumped into top connection 1, drilling fluid is entered by upper through-hole 12 in upper fluid cylinder 4, due to upper
Closing piece 5 is threadedly secured in top connection 1, therefore fluid cylinder 4 moves upwards on hydraulic drive, compressed spring 2, is exposed and is slided
Block 6, sliding block 6 release the locking to lower closing piece 7；Meanwhile drilling fluid is entered by lower through-hole 13 in lower fluid cylinder 8, pushes lower liquid
Cylinder 8 moves downward, and lower fluid cylinder 8 drives lower closing piece 7 to move downward, and sliding block 6 leaves groove in top connection 1 and lower closing piece 7 together
It moves downward, expansion cone 10 is pushed to move downward, start tube expansion.After stroke, pressure release pushes center-pole 9, lower 8 phase of fluid cylinder
Center-pole 9 is moved up, is resetted, sliding block 6 is returned in 1 unit with grooves in outer wall of top connection, and upper fluid cylinder 4 moves down under the effect of 2 pressure of spring,
Shelter from sliding block 6.First segment stroke terminates at this time, suppresses repeat the above process again, until all pipe is swollen complete.
It is understood that above with respect to the specific descriptions of the utility model, it is merely to illustrate the utility model and is not
The described technical solution of the utility model embodiment is limited to, it will be understood by those of ordinary skill in the art that, it still can be with
It modifies to the utility model or equivalent replacement, to reach identical technique effect；As long as meet using needs, all in this reality
Within novel protection domain.
