The drill bit for particle percussion drilling comprises a drill bit joint, a drill bit body and a cutting head, wherein a thread and a striking clamp are arranged on the drill bit joint, and the drill bit body is inlaid with gauge protection teeth and lateral incision teeth. The middle of the lower part of the cutting head is a conical and convex, and the outer edge of the lower part of the cutting head is provided with two sections of centrosymmetric annular lateral wings; the conical bulge at the middle of the lower part of the cutting head is provided with percussion teeth in an inlaying manner, and the two sections of annular lateral wings on the outer edge of the lower part of the cutting head are provided with cutting teeth in an inlaying manner; and nozzles are installed on the conical bulge at the middle of the lower part of the cutting head and the two sections of annular lateral wings on the outer edge of the lower part of the cutting head respectively. The drill bit for particle percussion drilling is suitable for the field of particle drilling, and capable of rapidly drilling in extra-hard stratums and soft-hard interacted stratums which are hard to drill by conventional drill bits, so that the drilling operation is more rapid and efficient.
Description
Technical field
The present invention relates to a kind of drill bit for particle impact drilling for the particle drilling well in the drilling bit field.
Background technology
The conventional drilling rock crushing tool mainly is drill bit at present, and the cutting way difference of various drill bits has determined that compliance is different, as: the PDC drill bit is to shear broken rock by the PDC tooth; The hard formation rock bit is by the cutter teeth rock fracture in dynamic indentation; Natural diamond is by the diamond scraping of high rigidity or the broken rock of grinding.The chief component of all these drill bits is bit adapter, drill body and bit, screw thread is arranged on the bit adapter and beat clamper, and drill body is inlaid with gauge teeth and side-cutting tooth.And all these drill bits need enough the pressure of the drill and moment of torsion to overcome the failure limit of rock in rock break-off process, be subject to the restriction of drilling rod and relevant downhole tool, the stress that drill bit cutting elements acts on rock is less, can not form efficient rock-breaking for burying the stratum dark, that the age is of a specified duration, compacting is heavy, intensity is high, drillability is poor, abrasiveness is strong.
Summary of the invention
Purpose of the present invention is exactly the problem that exists for prior art, and a kind of drill bit for particle impact drilling that is applicable to bad ground is provided.
The technical scheme of drill bit for particle impact drilling is: comprise bit adapter, drill body, bit, screw thread is arranged on the bit adapter and beat clamper, drill body is inlaid with gauge teeth and side-cutting tooth, after cutting radially has fan-shaped groove, the annular shoulder more than two sections that outer rim is centrosymmetric, the flank end studs with cutting teeth; Be the taper projection after the intermediate recess of bit bottom, taper projection outside studs with impact teeth.
Such scheme also comprises: be penetrated with nozzle in the annular shoulder of bit and taper projection.The sensing of nozzle and the axis of drill body are 10 ° to 45 ° angle.Drill body is inlayed the external diameter of gauge teeth part greater than the external diameter of inlaying the side-cutting tooth part.
The present invention is because the special construction of bit, after cooperating particle punching drilling technique, the extremely hard formation and the mutual stratum of soft or hard that make drill bit can the fast drilling conventional bit be difficult to creep into, rate of penetration increases substantially, reduced the rig activity duration, save drilling cost, drillng operation more rapidly and efficiently, overcome existing drill bit in rock break-off process, be subject to the restriction of drilling rod and relevant downhole tool, the stress that drill bit cutting elements acts on rock is less, and is dark for burying, age is of a specified duration, compacting is heavy, intensity is high, drillability is poor, the stratum that abrasiveness is strong can not form the difficult problem of efficient rock-breaking, can be widely used in oil, natural gas and mineral products production drilling well field.
Description of drawings
Fig. 1 is drill bit structure schematic diagram of the present invention
Fig. 2 be among Fig. 1 the bit cutting head part look up structural representation
Among the figure: 1. bit adapter, 2. drill body, 3. bit, 4. screw thread is 5. beaten clamper, 6. gauge teeth, 7. side-cutting tooth, 8. nozzle, 9. impact teeth, 10. cutting teeth.
The specific embodiment
The present invention is described further below in conjunction with the drawings and specific embodiments.
With reference to attached Fig. 1 and 2, drill bit for particle impact drilling comprises bit adapter 1, drill body 2, bit 3, screw thread 4 is arranged on the bit adapter 1 and beat clamper 5, and drill body 2 is inlaid with gauge teeth 6 and side-cutting tooth 7.Be taper projection, two sections annular shoulders that bit 3 bottom outer rims are centrosymmetric in the middle of bit 3 bottoms; The taper projection is installed with impact teeth 9 in the middle of bit 3 bottoms, after bit 3 radially has fan-shaped groove, is installed with cutting teeth 10 on two sections annular shoulders of bit 3 bottom outer rims; Be penetrated with nozzle 8 on taper projection and two sections annular shoulders of bit 3 bottom outer rims in the middle of bit 3 bottoms.Drill body 2 at the external diameter of inlaying the gauge teeth place greater than drill body 2 at the external diameter of inlaying the side-cutting tooth place.
Particle punching drilling is that circular steel body particle is added in the drilling fluid, and from a high speed ejection of bit nozzle 8, then fractured rock reclaims the stepout well process that steel grit recycles.In carrying out the particle punching drilling engineering, ground is provided with particle filling and the particle screening plant that utilizes particle punching drilling, the terminal drill bit for particle impact drilling that connects present embodiment of down-hole equipment.
