The lower end termination of described inner sleeve is convex, and inner sleeve lower end termination is provided circumferentially about screw key.
Described screw key quantity is 4, and screw key is set in the shape of a spiral on the circumference of interior its lower end termination.
Be provided with the inwall of described middle casing it is corresponding with screw key have a helicla flute, middle casing and inner sleeve it
Between be slidably connected by the cooperation of helicla flute and screw key.
Described guide shoe body multiple cutting tooths provided circumferentially about.
Described cutting tooth quantity is 6, wherein 3 cutting tooths are positive cutting tooth, another 3 cutting tooths are reversely cutting
Tooth.
Hydrophthalmia is provided with described lower house.
The beneficial effects of the present invention are：
During the full-bore casing guide tool work, drill string mode is put by above putting, realizes that guide shoe rotates, so as to pass through guide shoe
Body multiple cutting tooths provided circumferentially about remove well necking down and sand bridge；Expand compared to existing drillability hydro powered turbine or screw rod
Eye guide shoe, the full-bore casing guide tool construction is simple and is in full-bore state, without secondary brill removes again after the completion of well cementation
Turbine and screw portion, the cased efficiency of the complex structural wells such as high angle hole and horizontal well is improved, during so as to save
Between and cost.

Embodiment
The full-bore casing guide instrument is made up of upper shell 1, middle casing 2, lower house 3, inner sleeve 4 and guide shoe body 5,
The screw top of middle casing 2 is provided with upper shell 1, and the bottom of middle casing 2 is provided with lower house 3 by the screw thread of guide shoe body 5；
Hydrophthalmia 13 is provided with lower house 3.Inner sleeve 4 is movably installed with upper shell 1 and middle casing 2, the top of upper shell 1 is provided with
Casing joint 6, for connecting tubing string.Casing joint 6 is fixedly connected with inner sleeve 4.By close between upper shell 1 and inner sleeve 4
Seal 7 and ring washer 8 are provided with alignment bearing 9.Sealing ring 7, ring washer 8 and alignment bearing 9 are from top to bottom set gradually；
Wherein alignment bearing 9 plays centralizing function to inner sleeve 4, and sealing ring 7 seals while realizes the limit to alignment bearing 9
Position.
The lower end termination of inner sleeve 4 is convex, and the lower end termination of inner sleeve 4 is provided circumferentially about 4 screw keys 10.Spiral
Key 10 is set in the shape of a spiral on the lower end termination circumference of inner sleeve 4.It is provided with the inwall of middle casing 2 corresponding with screw key 10
Helicla flute 11, slided and be rotatably connected by the cooperation of helicla flute 11 and screw key 10 between middle casing 2 and inner sleeve 4.
5 provided circumferentially about 6 cutting tooths 12 of guide shoe body of the full-bore casing guide instrument.Wherein 3 cutting tooths 12 are
Positive cutting tooth, another 3 cutting tooths 12 are reverse cutting tooth, and during ensuring work, guide shoe body 5, which is rotated forward or inverted, all may be used
Effectively to be destroyed to barrier by cutting tooth 12（Referring to accompanying drawing 1）.
The full-bore casing guide tool work process is：
The screw key 10 of the bottom of inner sleeve 4 is located at the top of helicla flute 11 when initial, when encountering obstacle when decentralization, guide shoe body
5 stoppings that being hampered move downward, and are far longer than upper shell 1, middle casing 2, lower house 3 because inner sleeve 4 connects tubing string its gravity
The reason for guide shoe 5 overall gravity of body, inner sleeve 4 and casing joint 6 continue to prolong the slide downward of helicla flute 11, so as to drive upper casing
Body 1, middle casing 2, lower house 3 and the unitary rotation of guide shoe body 5, and larger a downward pressure and torsion are provided.
In this rotation, the positive can of cutting tooth 12 on guide shoe body 5 breaks the barriers such as sand bridge mud cake.
When being screwed into 11 bottom of helicla flute under screw key 10, the stop motion of inner sleeve 4, at this moment inner sleeve 4 is above carried,
Screw key 10 along helicla flute 1 move upwards while it is overall to upper shell 1, middle casing 2, lower house 3 and guide shoe body 5
Counter-rotational power is provided, so that upper shell 1, middle casing 2, lower house 3 and guide shoe body 5 are overall reverse
Rotate, cutting tooth 12 reverse on guide shoe body 5 can be destroyed again to barriers such as sand bridge mud cakes during rotation, so instead
It is multiple, until barrier is thoroughly destroyed, so that sleeve pipe continues smoothly decentralization.
The full-bore casing guide instrument uses all-pass gauge structure, internal unpowered structure, passes through above carrying to inner sleeve 4
The positive and negative rotation of guide shoe body 5 is realized with decentralization, meanwhile, lower house 3 can bore material using 3, after being easy to removing obstacles
Guide shoe bore remove work, avoid well cementation after the completion of again it is secondary bore remove turbine and screw portion, do not influence work of spudding in next time,
The part that brill may continue as sleeve pipe except back casing is continuing with, and improves the complex structural wells such as high angle hole and horizontal well
Lower tube efficiency, saves time and cost.
