Abstract
The utility model relates to the rotating drilling field, in particular relates to a drilling tool for cracking rock during drilling, namely a self-sharpening bit for rotating, which is mainly composed of a bit body (1), a lower bit body (2), a blade wing (3), cutting teeth (4) and a water passage (5) as well as a fixed brace (6). The tooth distributing structure of the bit has the character of self-sharpening and also adopts the self-sharpening tooth distributing mode; the cutting teeth and the blade wing are fixed by the fixed brace. By adopting the mode, the utility model prolongs the service life of the bit and substantially reduces the frequency of exchanging bit and lifting lower bit as well as the cost for frilling and largely enhances the drilling speed.
Description
Technical field
The utility model relates to field of oil drilling, particularly a kind of main tool that is used in fractured rock in the drilling process.
Background technology
In recent years, along with the requirement of drilling technology and the development of drilling technology, material and machine building industry, the design of drill bit, manufacturing and use have had very big development, and still among constantly developing, the kind and the scope of drill bit constantly enlarge, and the technology and the economic indicator of drill bit improve constantly.
At present, the drill bit that uses in rotary drilling is divided into rock bit, diamond drill bit and drag bit three major types, and all there is following problem in above-mentioned drill bit:
1. three class drill bits all have certain limitation in the use, and drag bit only is suitable for soft formation, and rock bit only is suitable for medium ground, and diamond bit is used for hard and hard formation.
2. above drill bit generally adopts the cloth tooth of individual layer face, thereby application life is short.
3. run into firm hard formation and layer of gravel, tooth is soon by blunt and smashing, thereby frequently puts brills, bit change, causes the drilling cost rising.
Summary of the invention
Footage per bit is few and the firm hard formation drill teeth is easy to wear in order to solve single of raising for the utility model, pass through the problem that the hard interbedded layer cutting teeth comes off easily and the scope of application is limited, having proposed a kind of rotation uses from sharp new drill, this drill bit structure is simple, from sharp cloth toothing, prolonged the application life of drill bit, and suitable and soft, in, reach various stratum such as hard firmly.Reduced bit change, the frequency that makes a trip, use simply, easy to operate, and pass through the layer of gravel performance and improve greatly.
The technical scheme that the utility model adopted is: this new drill by last bit body 1, down bit body 2, wing 3, cutting teeth 4, hydrophthalmia 5 and fixedly lacing wire 6 form.Last bit body 1 is positioned at drill bit top, and there is screw thread on top in order to connect drill string, and the side is surrounded by the groove of dress weldering wing 3; Following bit body 2 is welded on the bottom of bit body 1, and inside has hydrophthalmia 5 to be used to install nozzle; Wing 3 also claims wing, is inlaid with cutting teeth 4 on the wing 3, contacts with rock, is the critical piece of fractured rock.Cutting teeth 4 is stratiform and is embedded in wing 3 inside by arranging from sharp textural association, and fixedly lacing wire 6 is positioned at wing 3 back sides, is used for fixing cutting teeth 4.Fixedly lacing wire 6 is evenly to distribute, one at each single cutting teeth middle part, and cloth is one between per two teeth, and fixing lacing wire width unanimity.Two fixedly between the lacing wire 6 groove be circular-arc, and each recess width unanimity.
The beneficial effects of the utility model are: simple in structure, easy to use, and adopt fixedly lacing wire can reduce the risk that cutting teeth comes off, thereby prolonged drilling life of bit.
Description of drawings
Fig. 1 rotates and uses the self-sharpening bit structural representation;
Fig. 2 rotates and uses the self-sharpening bit vertical view.
The specific embodiment
Below in conjunction with drawings and the specific embodiments the utility model is further described, as shown in Figure 1, a kind of rotation self-sharpening bit mainly forms 5 by last bit body 1, following bit body 2, wing 3, cutting teeth 4, hydrophthalmia.Last bit body 1 is positioned at drill bit top, and following bit body 2 is welded on the bottom of bit body 1, is evenly distributed with hydrophthalmia 5 in following bit body inside, and the number of hydrophthalmia 5 is 3～6, can adjust the number of hydrophthalmia 5 according to the size of borehole size; Wing 3 be positioned at following bit body around, on wing 3 by be inlaid with cutting teeth 4 from sharp structure; Use fixedly lacing wire 6 to fix between with cutting teeth 4 and wing 3 at the back side of cutting teeth 4.Fixedly lacing wire 6 is evenly to distribute, one at each single cutting teeth middle part, and cloth is one between per two teeth, and fixing lacing wire width unanimity.Two fixedly between the lacing wire 6 groove be circular-arc, and each recess width unanimity.During the drill bit operate as normal, drill string drives the drill bit rotation by the screw thread on the last bit body 1, and the cutting teeth 4 on the wing 3 is broken and rock cutting along with the drill bit rotation.After the first floor cutting teeth 4 on wing 3 surfaces was by blunt, second layer cutting teeth 4 exposed out the broken and rock cutting of continuation, blunt one deck cutting teeth 4, and a toothrow of the new aspect of coming out guarantees that the tooth on cutting stratum has new tooth to occur all the time.
Claims (3)
1, a kind of rotary drilling self-sharpening bit mainly is made up of last bit body (1), following bit body (2), wing (3), cutting teeth (4), hydrophthalmia (5), and it is characterized in that: there is the fixedly fixedly lacing wire (6) of cutting teeth (4) at the back side of wing (3).
2, a kind of rotary drilling self-sharpening bit according to claim 1 is characterised in that: fixedly lacing wire (6) is for evenly distributing, one at each single cutting teeth middle part, and cloth is one between per two teeth, and fixing lacing wire width unanimity.
3, according to claim 1 or any described a kind of rotary drilling self-sharpening bit of claim 2, it is characterized in that: groove is circular-arc between two fixedly lacing wires (6), and each recess width unanimity.
