Detailed description of the invention
In order to more clearly explain technical characteristic of the present utility model, purpose effect, now comparison Figure of description enters
One step illustrates detailed description of the invention of the present utility model.
Referring to the drawings 1, this utility model provides a kind of salvaging type expandable casing patching and exempts to bore plug device, and this device includes opening
Dynamic device 1, multi-functional splined shaft 4, sliding sleeve 5, key block 6, guide shoe 7.Before expansion, package unit outer layer is trigger 1, in trigger 1
Portion is built-in with expansion cone 3, and expansion cone 3 inclined-plane closely cooperates with trigger 1 inner chamfer, and the middle upper position of trigger 1 has three
The individual rectangular channel (alternatively 4, depending on the expansion tube size with concrete application) being uniformly distributed along the circumference；It is machined with in the middle of expansion cone 3
Endoporus, endoporus is connected with expansion cone torr 2, and bottom tail end is machined with multi-functional splined shaft 4, and centre is through hole.3 Hes referring to the drawings
4, multi-functional splined shaft 4 outer surface upper end is cylindrical structural, and cylindrical structural top is an inclined-plane, and cylindrical structural bottom adds
Work has seal groove 42, is machined with splined shaft 43 below seal groove 42, and multi-functional splined shaft 4 bottom is a thinner column type one section
44, then lower section be a thinner column type two-stage nitration 46, bottom is male thread 47.It is through hole in the middle of multi-functional splined shaft 4, through hole
It is topmost spline 41, is box thread below spline 41；Box thread is downwards an elongated reducing venturi, has one in the middle of venturi
Inclined-plane 45, place.The splined shaft 43 sections of multi-functional splined shaft 4 outer surface is arranged with a sliding sleeve 5, and sliding sleeve 5 upper and lower side has ramp structure.
Referring to the drawings 5 and 6, it is through hole that sliding sleeve 5 body has in the middle of three rectangular channels being uniformly distributed along the circumference 52, sliding sleeve, and the through hole first half is
Spline 51.1 three rectangular channels of three rectangular channels 52 and trigger of sliding sleeve 5 overlap, and include three key blocks 6.7 Hes referring to the drawings
8, key block top is provided with inclined-plane 61, and bottom is arc structure.Referring to the drawings 9 and 10, multi-functional splined shaft 4 bottom connects guide shoe
7, guide shoe 7 is through-hole structure, and through hole upper end is a box thread 71, and guide shoe 7 bottom is hemisphere structure, uniform processing on hemisphere
Article four, rib structure 72.
Referring to the drawings 1, salvaging type expandable casing patching of the present utility model exempts to bore plug device when being embodied as, and arrives under tubing string
Well head high-pressure pump equipment is connected after in well.First pass through and accompany tubing string and this through hole exempting from boring device is circulated well-flushing, remove
Plug or metal ball, plug or metal ball outside dimension is sent into after foreign material less than at multi-functional splined shaft inner chamber slope 45 in pit shaft
Minimum diameter.Sealing function, multi-functional splined shaft 4 appearance is i.e. formed with slope 45 after plug or metal ball arrive slope 45
The sealing ring of face seal groove 42 seals the pressure between itself and trigger 1, is now formed between expansion cone 3 and seal groove 42 and seals
Space.By the further rising of pressure, after reaching the desirable pressure that expansion tube expands, well head lifting means keeps accompanying tubing string
Former suspending weight at the uniform velocity on carry, up distending expansion tube body under expansion cone 3 action of hydraulic force, the spline in expansion cone torr 2 is from many merits
Can start at splined shaft 4 through hole upper end spline 41 to depart from up, until having expanded whole expansion body.
Salvaging type expandable casing patching of the present utility model is exempted to bore plug device and is expanded after operation completing, upper proposition expansion cone 3,
Enter down interlocking connector 8, when interlocking connector 8 exempts to bore in plug device after multi-functional splined shaft 4 down to the contact of trigger 1 position,
Rotate tubing string, make the male thread 81 of interlocking connector 8 lower end be connected with the box thread of multi-functional splined shaft 4 inner chamber, above carry drilling tool,
The multi-functional relative sliding sleeve 5 of splined shaft 4 and key block 6 run up, i.e. one section 44 of splined shaft lower cylindrical type and sliding sleeve 5 and key block 6
Bottom arc structure 62 occur relatively to slide, now guide shoe 7 is upwards transported male thread 47 is synchronize with under the effect of box thread 71
Dynamic.When column type passes fully through sliding sleeve 5 and key block 6 for one section 44, key block 6 is laterally corresponding to the post two of multi-functional splined shaft 4 circle
Section 46.Carrying drilling tool in continuation, expansion tube has expanded complete, and trigger 1 position will not change, right along meeting on three rectangular channels
Inclined-plane 61 on key block 6 produces the stress being perpendicular to inclined-plane 61 obliquely.Under this stress effect, 3 key blocks fall into sliding sleeve 5 He
In the cavity produced between column type two-stage nitration 46, due to the restriction of size, key block 6 still embeds in the rectangular channel 52 in sliding sleeve 5.?
During carrying drilling tool on afterwards, the ramp structure that sliding sleeve 5 upper and lower side has can reduce on carry the resistance of process, apparatus above will
It is suggested well head with this state, completes expandable casing patching and exempt to bore the salvaging of plug device.
In this utility model salvaging type expandable casing patching exempts from the operation process of brill plug device, enter two set drilling tools under needing altogether and enter
OK: (1), referring to the drawings 1, first drilling tool completes the subsidy operation of expansion tube, proposes expansion cone 3 and above mechanism；(2) reference
Accompanying drawing 2, under enter interlocking connector 8, complete the connection of multi-functional splined shaft 4 inner chamber box thread and interlocking connector male thread, now key
Block lock-out state in sliding sleeve 5 and trigger 1 rectangular channel, above carries drilling tool, makes key block be in sliding sleeve 5 and column type two-stage nitration 46
Between produce cavity in, now key block no longer play the whole series exempt from bore plug device position-limiting action, continue to trip out interior tubing string.The party
Formula can be used for the construction of big section expandable casing patching, is not subject to down expansion tube length limitation, it is not necessary to operator provides well power-equipment, carries
High efficiency of construction, has saved construction cost.
The foregoing is only the schematic detailed description of the invention of this utility model, non-for limiting model of the present utility model
Enclose.Any those skilled in the art, equivalent done on the premise of without departing from design of the present utility model and principle becomes
Change and amendment, the scope of this utility model protection all should be belonged to.
