Specific embodiment
The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the invention.
As shown in Figs. 1-5, a kind of chance card buries the drill bit that can give up, including the drill body 2 and outer cylinder 1 being vertically arranged, outer cylinder 1
It is set on drill body 2, lock nut 3 is equipped between the top of drill body 2 and the top of outer cylinder 1, the bottom surface of outer cylinder 1 is opened
Equipped with multiple torsion pass slots 13, the middle part of drill body 2 is equipped with multiple torsion pass blocks 10, and torsion pass block 10 and institute's torsion pass slot 13 correspond
It is cooperatively connected, the top of drill body 2 is equipped with external screw thread A11, and lock nut 3 is threadedly coupled with external screw thread A11 and presses outer cylinder 1
On tight drill body 2.
Specifically, torsion pass block 10 and torsion pass slot 13 are plugged on correspondingly in torsion pass slot 13 during drill string is sent into,
Since torsion pass block 10 and torsion pass slot 13 cooperate, the torque of outer cylinder 1 can deliver torque to drill body 2 by this connection type；
Locking screw is connect with lock nut 3, it is ensured that outer cylinder 1 and drill body 2 have certain preload in the axial direction, to prevent bit operation
It is loosened in the process because of axial vibration.
Preferably, torsion pass block 10 is substantially in cuboid, and multiple torsion pass blocks 10 are arranged circumferentially shape along drill body 2
At concave-convex structure, the shape of torsion pass slot 13 and torsion pass block 10, which is adapted, to be meshed together.
Drill body 2 includes pedestal 5, the support portion 6 of tubular and the fixation of tubular for the tubular being sequentially communicated from top to bottom
Portion 7, the diameter of pedestal 5 are greater than the diameter of support portion 6, and the diameter of support portion 6 is greater than the diameter of fixed part 7, multiple torsion pass blocks 10
Being arranged circumferentially and being fixedly connected with the end of pedestal 5 along support portion 6, the middle part of fixed part 7 offers annular groove 12,
External screw thread A11 is provided with the top of fixed part 7 and is located at the top of annular groove 12, and outer cylinder 1 is set in support portion 6 and fixed part
Outside 7.
Specifically, area of section is relatively minimal at annular groove 12 on drill body 2, under certain pulling force effect,
Position fracture may be implemented drill bit and give up.
Outer cylinder 1 includes the interconnecting piece 8 of tubular and the connector portions 9 with external screw thread B, and interconnecting piece 8 is set in outside support portion 6,
Connector portions 9 are set in outside fixed part 7, and torsion pass slot 13 is provided on the bottom surface of interconnecting piece 8, and lock nut 3 is arranged in connector portions 9
It is interior.The middle part of interconnecting piece 8 offers spanner slot 14.
Specifically, interconnecting piece 8 and connector portions 9 are integrally formed.Pedestal 5, support portion 6 and fixed part 7 are integrally formed.It is preferred that
, pedestal 5, support portion 6 and fixed part 7 are cylinder, and periphery wall is smooth surface, make to be easy landing using spanner, lead to
It crosses and opens up spanner slot 14, spanner can be stuck in spanner slot 14, is easy to use.
Fluid erosion prevention cap 4 is equipped in the top of fixed part 7, fluid erosion prevention cap 4 and the interference fit of fixed part 7 connect, fluid erosion prevention cap 4
Top surface on be fixed with outer six sides 16, interior hexagonal hole 15 is fixed on the top surface of lock nut 3, including outer six side 16 is cooperatively connected
In hexagonal hole 15.The inner wall on 4 top of fluid erosion prevention cap is covered with fluid erosion prevention layer.
Specifically, fluid erosion prevention layer uses anti-erosion material, it can be effectively prevented and fail under mud souring.Fluid erosion prevention
4 lower part of cap and 7 inner cavity of fixed part are interference fitted, and prevent fluid erosion prevention cap in drilling vibration processes from loosening.
It, can be directly by applying the pulling force to drill string, since drill string and fluid erosion prevention cap 4 closely connect after encountering tubing string and being buried by card
It connecing, fluid erosion prevention cap 4 is connect with lock nut 3, and lock nut 3 and fixed part 7 are threadedly coupled, pulling force is passed into fixed part 7, by
Cross section is relatively smaller elsewhere at the annular groove 12 of fixed part 7, is broken at first after applying certain pulling force, that is, passes through drawing
At abscission ring connected in star 12, it is broken drill body 2, abandons most drill body 2, salvages the device on drill bit top as revolved
Turn well system, reduces economic loss.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
