Description
Technical field
The present invention relates to drilling technique field, in particular to a kind of particle impacting drill bit.
Background technology
At present, along with the development of industrial technology, the demand of various countries to petroleum resources constantly increases.But, along with the continuous exhaustion of Shallow Oil-Gas resource, find under new petroleum resources concentrated on deep formation and complex geological condition, but due to traditional drilling technology limited, deep-well and ultradeep well hard formation drilling well ubiquity speed is slow, the cycle long, high in cost of production problem.
Summary of the invention
Technical problem to be solved by this invention is, provides the drill bit that a kind of drilling efficiency is higher.
Therefore, technical scheme of the present invention is as follows:
A kind of particle impacting drill bit, comprise main body, the lower end of described main body forms three spiral flanks, adjacent be between described spiral flank formed rotate chip area, for discharging landwaste and particle when described particle impacting bit operation, wherein two described spiral flanks are respectively arranged with a flank nozzle, in described main body lower end, also central nozzle is provided with between three described spiral flanks, the spacing of the axis of described central nozzle and described main body is less than the distance between described flank nozzle and the axis of described main body, the outlet diameter of two described flank nozzles is 3 ~ 4 times of the outlet diameter of described central nozzle.
In this technical scheme, provide a particle impacting drill bit, adopt three spiral flanks, formed between adjacent spiral flank and rotate chip area, chip removal better effects if, is conducive to the recovery of particle; The spacing of the axis of central nozzle and main body is less than the distance between flank nozzle and the axis of main body, and the outlet diameter of two flank nozzles is 3 ~ 4 times of the outlet diameter of central nozzle, can better to ensure that each several part breaks rock speed even.
In addition, the position triangularity of described central nozzle and two described flank nozzles is arranged, ensures that broken rock speed is even further; Sum up according to practical experience, the outlet diameter of described central nozzle is 5 ~ 8mm; The outlet diameter of described flank nozzle is 15 ~ 20mm, and the runner of described central nozzle becomes 8 ~ 12 ° of angles with the axis of described main body, and the runner of described flank nozzle becomes 20 ~ 25 ° of angles to be best with the axis of described main body.
Accompanying drawing explanation
Fig. 1 is the structural representation of the particle impacting drill bit according to the embodiment of the present invention;
Fig. 2 and Fig. 3 is the polycrystalline substance schematic diagram of particle impacting drill bit in Fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.It should be noted that, when not conflicting, the feature in the embodiment of the application and embodiment can combine mutually.
As shown in Figure 1, particle impacting drill bit according to an embodiment of the invention, comprise main body 2, the lower end of described main body 2 forms three spiral flanks 3, adjacent be between described spiral flank 3 formed rotate chip area 4, for discharging landwaste and particle when described particle impacting bit operation, wherein two described spiral flanks 3 are respectively arranged with a flank nozzle 31, in described main body 2 lower end, central nozzle 21 is also provided with between three described spiral flanks 3, the spacing of the axis of described central nozzle 21 and described main body 2 is less than the distance between described flank nozzle 31 and the axis of described main body 2, the outlet diameter of two described flank nozzles 31 is 3 ~ 4 times of the outlet diameter of described central nozzle 21.
Wherein, in figure, 1 is top connection, and 5 is cutting teeth, and 22 is runner.
In this technical scheme, provide a particle impacting drill bit, adopt three spiral flanks 3, formed between adjacent spiral flank 3 and rotate chip area 4, chip removal better effects if, is conducive to the recovery of particle; The spacing of the axis of central nozzle 21 and main body 2 is less than the distance between the axis of flank nozzle 31 and main body 2, the outlet diameter of two flank nozzles 31 is 3 ~ 4 times of the outlet diameter of central nozzle 21, can better to ensure that each several part breaks rock speed even.
In addition, described central nozzle 21 and two described flank nozzle 31 triangularities are arranged, ensure that broken rock speed is even further; Sum up according to practical experience, the outlet diameter of described central nozzle 21 is 5 ~ 8mm; The outlet diameter of described flank nozzle 31 is 15 ~ 20mm, and the runner of described central nozzle 21 becomes 8 ~ 12 ° of angles with the axis of described main body 2, and the runner of described flank nozzle 31 becomes 20 ~ 25 ° of angles to be best with the axis of described main body 2.
In order to provide the power accelerating jet to cleaner for high-pressure drilling fluid and converted steel particle, nozzle flow channel is ad hoc counts cone shape, in order to nozzle is easy for installation, at a bit of cylinder of the ad hoc meter in particle outlet place.Wherein nozzle length and diameter ratio are approximately 4, and nozzle length is 30mm ~ 50mm, and nozzle cylindrical section length and conical section length ratio are between 3:1 ~ 4:1.
Particle flux enters three nozzles branch flow passage separately from the total runner in drill bit top, is then sprayed with high speed by three high pressure nozzles, and the tensile stress produced due to its high-speed impact effect and shear stress are greater than the ultimate strength of rock, cause catalase.Simultaneously under the percussion of cleaner for high-pressure drilling fluid, landwaste is returned to ground through helical flute 4.
In sum, content of the present invention is not limited in the above-described embodiment, and those skilled in the art can propose other embodiment within technological guidance's thought of the present invention, but this embodiment all comprises within the scope of the present invention.
