Huge change.If by the tooth of the 1980s, compared with current tooth, difference is sizable.Due to mixed
The change of technique and manufacturing process is closed, the capability and performance of current cutting tooth is far better, makes the Anti-erosion and anti-impact of drill bit
Ability is hit all to greatly improve.
Existing PDC drill bit has the characteristics that drilling speed is high, drilling depth is long, down-hole accident is few, excellent combination property, obtains extensively
Using.But easily generation bit balling, torque ripple are big in use, directional orientation tool face is unstable, have had a strong impact on PDC drill bit
Service efficiency, the speed of operation, and add drilling cost.
Utility model content
The shortcomings that the purpose of this utility model is to overcome prior art, there is provided one kind combination wing formula, anti-mud drum phenomenon,
The anti-mud drum orientation PDC drill bit of working stability.
The purpose of this utility model is achieved through the following technical solutions：A kind of anti-mud drum orientation PDC drill bit, it includes boring
Head main body, conventional structure wing and without gauge structure wing, described drill main body is that class is cylindric, the top ends of drill main body
Certain angular interval is fixed and offers conventional structure wing and without gauge structure wing, conventional structure wing and without gauge structure knife
The wing is around the spaced setting of bit center line, conventional structure wing and without being chip area between gauge structure wing, routinely
Structure wing and be free of gauge without the PDC cutting tooths that similar arrangement is provided with gauge structure wing, no gauge structure wing
Chip removal region is also formed at face, the bottom of no gauge structure wing, and chip area and chip removal region collectively form the chip removal of drill main body
Passage.
Further, the groove center portion of described chip area offers the nozzle for spraying coolant or cleaning fluid.
Further, the lower end of described drill main body is provided with the joint for being connected with drilling equipment.
Further, described conventional structure wing and without forming theoretical gauge line of demarcation between gauge structure wing, is managed
By being chip removal region between gauge line of demarcation and the bizet of drill main body.
The utility model has advantages below：
1st, a kind of anti-mud drum orientation PDC drill bit described in the utility model has combination wing formula, the property of anti-mud drum phenomenon
Energy feature, the wing of this PDC drill bit form by conventional structure wing and without gauge structure wing, wing wound drill bit pivot
Line 4 is distributed, and the region between adjacent blades is chip area, and chip removal region, chip area are also formed at the bottom of no gauge structure wing
The channel of chip removal of drill main body is collectively formed with chip removal region, improves the area of PDC drill bit chip removal, reduces PDC drill bit hair
The probability of raw mud drum.
2nd, a kind of anti-mud drum orientation PDC drill bit described in the utility model also has the characteristics of working stability, due to routine
Structure wing and the combination without gauge structure wing, the contact area of PDC drill bit and the borehole wall is reduced, be advantageous to reduce PDC brills
Frictional resistance between head and the borehole wall, reduce torque ripple during PDC drill bit drilling, so as to improve work when PDC drill bit orients
The stability in tool face.

Embodiment
The utility model is further described below in conjunction with the accompanying drawings, but the scope of protection of the utility model is not limited to
It is as described below.
As shown in Fig. 1 ~ Fig. 2, a kind of anti-mud drum orientation PDC drill bit, it includes drill main body 1, conventional structure wing 2 and nothing
Gauge structure wing 3, described drill main body 1 are that class is cylindric, and the top ends certain angular interval of drill main body 1, which is fixed, to be opened up
There is conventional structure wing 2 and without gauge structure wing 3, conventional structure wing 2 and without gauge structure wing 3 around bit center
4 spaced setting of line, conventional structure wing 2 and without being chip area 12 between gauge structure wing 3, the He of conventional structure wing 2
Without the PDC cutting tooths 6 that similar arrangement is provided with gauge structure wing 3, no gauge structure wing 3 is free of gage surface, no guarantor
Chip removal region 7 is also formed at the bottom of gauge structure wing 3, and the chip removal that chip area 12 and chip removal region 7 collectively form drill main body 1 is led to
Road.
Further, opened up as preferred embodiment of the present utility model, the groove center portion of described chip area 12
There is the nozzle 5 for spraying coolant or cleaning fluid；The lower end of described drill main body 1 is provided with for being connected with drilling equipment
Joint 8；Described conventional structure wing 2 and without forming theoretical gauge line of demarcation 10, theoretical gauge between gauge structure wing 3
It is chip removal region 7 between the bizet of line of demarcation 10 and drill main body 1.
Installation process of the present utility model and use process are as follows：By each parts of the present utility model according to Fig. 1 ~ figure
Annexation and position relationship shown in 2 are installed and processed, and can be begun to use after the utility model installation.This
