Description
Technical field:
The present invention relates to enter technical field, especially under a kind of deep-well, extended reach well and labyrinth casing
Relate to entering auxiliary device under a kind of labyrinth casing.
Background technology:
Along with deep-well, ultradeep well, the extensive application of various complex structural well, require more to come to Casing running technology
The highest.Due to borehole condition, property of drilling fluid, down hole problem, often hinder, card phenomenon.Generally
In the case of, take short to carry, the measure effect such as reaming and allotment mud inconspicuous if, just need to carry sleeve pipe,
Drilling through down well, the most again transfer sleeve pipe, this process not only expends substantial amounts of human and material resources, and
Also greatly increases well construction period, therefore for avoiding the setting of casings such as Holes of Complicated Wells, deep-well, extended reach well during
There are complex situations, need to develop the auxiliary device entered under a kind of sleeve pipe, ensure to enter under sleeve pipe is smoothly.
Summary of the invention:
The technical problem to be solved in the present invention is to provide under a kind of labyrinth casing and enters auxiliary device, this dress
Put achieve during setting of casing can rotary cutting operation, reach to repair the borehole wall, abolish the function of sand bridge,
Ensure at the bottom of deep-well, ultradeep well, the various smooth lower going-into-well of complex structural well completion casing, shorten and bore completion period.
Overcome the deficiency entering the card that is easily hampered, meets under existing deep-well, ultradeep well, various labyrinth casing.
The technical solution used in the present invention is: enter auxiliary device under a kind of labyrinth casing, including on
Joint and body；Top connection lower end connects body, and top connection inwall connects support valve, the center of support valve
Groove connects screw rod by upper bearing (metal), has multiple duct, under screw rod outside the central recess of support valve
Hold by variable buckle joint connect bearing rod, bearing rod lower end connect three wings fish tail bit, bearing rod bottom with this
Lower bearing is installed between body, bearing rod upper portion side wall has passage, three wings fish tail bit has hydrophthalmia.
The invention has the beneficial effects as follows: present invention achieves during setting of casing can rotary cutting operation, reach
To the finishing borehole wall, abolish the function of sand bridge, ensure deep-well, ultradeep well, various complex structural well completion casing
Smoothly at the bottom of lower going-into-well, shorten and bore completion period.
Accompanying drawing illustrates:
The present invention will be further described in detail with detailed description of the invention below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the structural representation of support valve.
Fig. 3 is the right view of Fig. 2.
Fig. 4 is the structural representation of three wings fish tail bit.
Fig. 5 is the right view of Fig. 4.
Detailed description of the invention:
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, under a kind of labyrinth casing, enter auxiliary device,
Including top connection 1 and body 3；Top connection 1 lower end connects body 3, and top connection 1 inwall connects support valve
2, the central recess of support valve 2 connects screw rod 4, outside the central recess of support valve 2 by upper bearing (metal) 8
Having multiple duct, screw rod 4 lower end connects bearing rod 6 by variable buckle joint 5, and bearing rod 6 lower end connects
Three wings fish tail bit 7, installs lower bearing 9, bearing rod 6 upper portion side wall between bearing rod 6 bottom and body 3
On have passage, three wings fish tail bit 7 has hydrophthalmia.
During use, top connection 1 is connected to sleeve pipe and alters lower end, and support valve 2 is disk with holes around intermediate groove,
When drilling fluid flows into body 3 inside by support valve 2, linkage spiral bar 4 rotates, centered by screw rod 4
Design quality of rubber materials flight on round bar, when liquid flow impact flight drives center round bar to rotate, carry simultaneously
Dynamic bearing rod 6 rotates, and by bearing rod 6, rotational power is passed to three wings fish tail bit 7, and then realizes rotation
Turn the function of cutting.Drilling fluid passes through body 3, and the runner on bearing rod 6 enters three wings fish tail bit 7,
Realizing the connection of drilling fluid, three wings fish tail bit 7 is the critical piece that cutting rotates, by cutting tip and upper
Portion's connector connects, and devises horizontal and vertical hydrophthalmia on three wings fish tail bit 7, it is achieved nearly drill bit rock
Effective removing of bits.The present invention has certain traction function, and rolling wheel centralizer can be coordinated to use under raising
Set tube efficiency, it is achieved sleeve pipe is directed into well, can substitute for casing shoe and uses, reduce construction cost, under prevention
Sleeve pipe down-hole accident, can carry out pretreatment to well.
It is understood that above with respect to the specific descriptions of the present invention, be merely to illustrate the present invention and be not subject to
It is limited to the technical scheme described by the embodiment of the present invention, it will be understood by those within the art that, still
The present invention can be modified or equivalent, to reach identical technique effect；Need are used as long as meeting
Want, all within protection scope of the present invention.
