Description
Technical field:
This utility model relates to horizontal well heavy repair task technical field, can move back can drag for particularly to a kind of horizontal well
Formula internal cutting device.
Background technology:
Bigger than straight well in the task difficulty of horizontal well overhaul replacing screen casing, sleeve pipe, a lot of straight well heavy repair tasks make
Instrument be easy to break down when using in horizontal well.More casing replacing, screen casing are usually taken and first descend work
Tool tubing string cutting, then carry out the operation of tubing string fishing.Owing to horizontal well is typically all barefoot completion, as
Horizontal well oil-producing formation is sandstone reservoirs, it is easy to shake out, and changes in screen casing, casing operation in overhaul and puts
Put tubing string and be susceptible to sand card；At net horizontal section, after the instrument cutting work of working string bottom completes,
Due to gravity, strata pressure affect the screen casing that cuts down, sleeve pipe carry on tubing string after the most in the wellbore with
Original sleeve pipe, screen casing produce dislocation, and then affect next step fishing.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of horizontal well can move back salvagable internal cutting device,
The arrangement achieves and have only to remove one-trip string and can complete down-hole casing, the cutting of screen casing, salvaging,
And also can exit when meeting card, decrease working procedure, reduce operating expenses, it is to avoid after having cut
There is the hidden danger of dislocation in sleeve pipe that upper lifting pipe post causes, screen casing, improves the success rate of when repairing horizontal well operation.
Overcome existing level casing, the cutting of screen casing, salvage need under twice tubing string complete, after having cut
Upper lifting pipe post easily causes sleeve pipe, the deficiency of screen casing generation inconsistent phenomenon.
Technical solution adopted in the utility model is: a kind of horizontal well can move back salvagable internal cutting device, bag
Include top connection, outer tube body and centralizer body；Top connection, outer tube body and centralizer body are sequentially connected with, centralizer body bottom
Being provided with guide cone, outer tube body outer wall axially has chute, sliding sleeve is sleeved on outer tube body and can be along outer tube
Chute on body moves up and down, and sliding sleeve lower end connects grappling slips, outer tube body is set with conical surface set and holds up
Just overlapping, conical surface set lower end connects supporting positive cover, and inclined-plane, grappling slips lower end is against on the conical surface of conical surface set, spring
Upper end withstands on supporting positive cover lower end surface, and lower spring end withstands on the end face of centralizer body upper end, on centralizer body sidewall
Having installation passage, blade is connected to install on channel side wall by bearing pin, and outer tube body is provided with core inside lower end
Axle, outer tube body inwall is provided with convex key, and this convex key stretches in the outer wall chute of mandrel, and mandrel lower end pin connects cutter
Sheet push rod, blade push rod other end pin is connected in the installation passage on centralizer body sidewall, and mandrel moves up
Band cutting blade push rod can be released the installation passage of centralizer body by blade, mandrel bottom is provided with limit spring, limit
Position lower spring end withstands on centralizer body inwall step.
The beneficial effects of the utility model are: this utility model achieve have only to remove one-trip string can be complete
Down-hole casing, the cutting of screen casing, salvaging in pairs, and also can exit when meeting card, decrease working procedure,
Reduce operating expenses, it is to avoid cut sleeve pipe that rear upper lifting pipe post causes, screen casing occurs the hidden of dislocation
Suffer from, improve the success rate of when repairing horizontal well operation.
Accompanying drawing illustrates:
The utility model is described in more detail with detailed description of the invention below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
As it is shown in figure 1, a kind of horizontal well can move back salvagable internal cutting device, including top connection 1, outer tube body 2
With centralizer body 9；Top connection 1, outer tube body 2 and centralizer body 9 are sequentially connected with, and centralizer body 9 bottom is provided with guiding
Cone 13, outer tube body 2 outer wall axially has chute, and sliding sleeve 3 is sleeved on outer tube body 2 and can be along outer tube
Chute on body 2 moves up and down, and sliding sleeve 3 lower end connects grappling slips 4, and outer tube body 2 is set with the conical surface
Set 5 and supporting positive cover 6, the conical surface overlaps 5 lower ends and connects supporting positive cover 6, and inclined-plane, grappling slips 4 lower end is against conical surface set
On the conical surface of 5, spring 7 upper end withstands on supporting positive cover 6 lower end surface, and spring 7 lower end withstands on centralizer body 9
On end end face, centralizer body 9 sidewall having installation passage, blade 10 is connected to install channel side by bearing pin
On wall, being provided with mandrel 8 inside outer tube body 2 lower end, outer tube body 2 inwall is provided with convex key, and this convex key stretches into mandrel
In the outer wall chute of 8, mandrel 8 lower end pin connects blade push rod 11, and blade push rod 11 other end pin is connected to
In installation passage on centralizer body 9 sidewall, mandrel 8 move up can band cutting blade push rod 11 by blade 10
