Abstract
The invention relates to a guiding drill bit which comprises a bit body. An impactor casing is fixedly connected with the middle of the bit body, an axis of the impactor casing and an axis of the bit body form an angle alpha, a hydraulic oscillator is fixedly installed in the impactor casing, an impact drill bit is connected with the inside of the impactor casing in an upward and downward moving mode, and the front end of the impact drill bit penetrates out of the impactor casing. The hydraulic oscillator is fixedly installed in the impactor casing through an oscillator fixing seat which is fixedly connected with the rear end of the impactor casing. According to the guiding drill bit, the axis of the impactor casing and the axis of the bit body form the angle alpha, and the impact drill bit plays a role in guiding the bit body when the impact drill bit breaks rock along the direction of the angle. The impactor casing is fixed relative to a deflection position of the axis of the bit body and can be marked on a drill floor, when the position of a borehole is required to be adjusted, the position of the impactor casing can be adjusted through a method of rotating a drill column on the ground so as to achieve guiding drilling, and the using effects are good.
Description
Technical field
The present invention relates to a kind of guide drilling tool, relate in particular to a kind of steerable drilling drill bit.
Background technology
In the existing steerable drilling operation, add slidingtype NDS that power drilling tool forms and rotary steerable drilling system as main take bent sub, but result of use is bad.
Summary of the invention
The present invention is directed to deficiency, a kind of have guide effect, steerable drilling drill bit that result of use is good are provided.
The technical scheme that the present invention solves the problems of the technologies described above is as follows:
A kind of steerable drilling drill bit, comprise drill bit, it is characterized in that, be fixedly connected with the impactor shell in the middle of the drill bit, has angle α between the axis of impactor shell and the axis of drill bit, be installed with hydroscillator in the impactor shell, the up and down impact bore bit that is connected with in the impactor shell impacts the bore bit front end and passes from impacting the bore bit front end.
According to described a kind of steerable drilling drill bit, it is characterized in that, described hydroscillator is fixedly mounted in the described impactor shell by the oscillator holder, and the oscillator holder is fixedly connected on described impactor outer casing back.
In the present invention, because the axis of impactor shell and the axis of drill bit have certain angle α, impact bore bit and can play guide effect to drill bit along this direction fractured rock.The impactor shell is fixed with respect to the deflection orientation of drill axis, can give mark at rig floor, when needs are adjusted Borehole Azimuth, is the orientation of capable of regulating impactor shell by the method at the ground rotary drill column, leads with this and creeps into, and result of use is good.
Description of drawings
Fig. 1 is structural representation of the present invention.
In the accompanying drawing:
1, oscillator holder; 2, hydroscillator; 3, impactor shell; 4, impact bore bit; 5, drill bit.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present invention and feature are described, institute gives an actual example and only is used for explaining the present invention, is not be used to limiting scope of the present invention.
A kind of steerable drilling drill bit, as shown in Figure 1, comprise drill bit 5, be fixedly connected with impactor shell 3 in the middle of the drill bit 5, has angle α between the axis of the axis of impactor shell 3 and drill bit 5, be installed with hydroscillator 2 in the impactor shell 3, impactor shell 3 interior up and down being connected with are impacted bore bit 4, impact bore bit 4 front ends and pass from impacting bore bit 4 front ends.In the present embodiment, hydroscillator 2 is fixedly mounted in the impactor shell 3 by oscillator holder 1, and oscillator holder 1 is fixedly connected on impactor shell 3 rear ends.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
In the present invention, oscillator holder 1 is used for compressing hydroscillator 2, hydroscillator 2 designs according to Principles of Acoustics, there is not movable part, after drilling fluid enters hydroscillator 2, through self-oscillation process such as resonance, feedback, frequency-selecting and amplifications, form pulsing jet and act on impact bore bit 4, the pressure fluctuation of jet is converted into the periodic shock load of impact bore bit 4, thereby impacts, fractured rock.
