Abstract
The utility model relates to a diamond-impregnated bit. The diamond-impregnated bit comprises a body, wherein at least eight blades are evenly distributed on the end surface of the body along the circumference of the surface of the body, gauge protection blocks connected with the blades are distributed on the surface of the periphery of the body, the front end of every blade is provided with a nozzle, the center of the body is provided with a nozzle, every blade is provided with cutting teeth, first impregnated columns, second impregnated columns, third impregnated columns and artificial polycrystalline diamond blocks, the first impregnated columns and the second impregnated columns are alternatively distributed at an circular arc transition position of the blade center to the corresponding gauge protection block, and the third impregnated columns and the artificial polycrystalline diamond blocks are distributed on the gauge protection block. The diamond-impregnated bit is reasonable in design, replaces an original integrated impregnated cutting structure with a split type impregnated cutting structure, can further increase the density of tooth distribution of the structure due to the fact that impregnated columns of different structures are distributed alternatively, can improve cutting force and rock breaking efficiency, is good in abrasion resistance, and can prolong service life.
Description
Technical field
The utility model relates to a kind of diamond-impregnated bit, is specifically related to a kind of diamond-impregnated bit for geological prospecting that cuts great efforts, long service life, is mainly used in the exploration of shale, mud stone, limestone.
Background technology
Impregnated bit belongs to earth-boring bit, is used to creep into the lithostratigraphy relatively hard and/or abrasion resistance such as sandstone, has advantages of the stratum that can adapt to drillability extreme difference.Conventional impregnated bit is generally taked whole wing formula design, i.e. an as a whole impregnated cutting structure of wing, and the advantage of this structure is that the layout density of impregnated cutting structure is high, and extended the application life of drill bit.But whole impregnated step cutting structure bit is when boring chance medium ground, and the ability of formation drilling is poor, can not effectively improve rate of penetration.
Impregnated post mainly contains cylinder, cylindroid or triangular prism etc., its bizet is generally single-curved surface, and curve form is taper seat, hemisphere face or plane etc., during impregnated post formation drilling that bizet is plane and the contact area on stratum larger, therefore the effect of cutting is poor, but application life is longer; Bizet is the impregnated post of taper seat or sphere, although reduced the contact area with stratum, the vertex of a cone or ball top are easily worn down to plane and lost efficacy, and application life is shorter.
Therefore, adopt split type impregnated cutting structure to replace the impregnated cutting structure of original monolithic,, the impregnated post of different structure is set on wing meanwhile, can strengthen the cutting dynamics of impregnated bit, increase the service life.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of diamond-impregnated bit that cuts great efforts, long service life.
For addressing the above problem, the technical scheme that the utility model adopts is as follows:
A kind of diamond-impregnated bit, comprise body, on the end face of described body, even circumferential at least 8 wings that distribute surfacewise, circumferential surface at described body is distributed with the gauge piece being connected with described wing, at the front end of described wing 1 nozzle that respectively distributes, 1 nozzle of central distribution at described body, on described wing, cutting teeth is installed, the first impregnated post, the second impregnated post, the 3rd impregnated post and diamond glomerocryst are inserted, described the first impregnated post and described the second impregnated post are alternately distributed the arc transition position of mind-set gauge piece in wing, described the 3rd impregnated post and described diamond glomerocryst are inserted and are distributed on gauge piece.
Adopt split type impregnated cutting structure to replace the impregnated cutting structure of original monolithic, difform impregnated post is alternately embedded on wing, form the drill bit of split type impregnated cutting structure, can further reduce the cutter set density of structure, strengthen cutting dynamics, the efficiency of breaking rock that strengthens impregnated bit, increases the service life.In the utility model, adopt the first impregnated post, the second impregnated post, the 3rd impregnated post and diamond glomerocryst to insert and be alternately distributed the mode on wing, can play the effect of protection drill bit, enhancing cutting dynamics.
In order to improve the stability of drill bit, strengthen practicality, the utility model is on the body of drill bit, preferably, be 45 degree angles and be evenly distributed 8 wings, making like this has more a plurality of blades contacts shaft bottom on the cutting face of drill bit, can strengthen cutting dynamics, and described wing is on same horizontal plane, is not easy run-off the straight.
In order to improve the anti-wear performance of impregnated bit, the utility model is inlaid with diamond glomerocryst on wing, can keep keen edge, reaches the object that improves bit life.
For the landwaste in centre, shaft bottom is rinsed well, the utility model is at 1 nozzle of central distribution of described body, meanwhile, at the front end of described wing 1 nozzle that respectively distributes, the area rinsing increased, and dynamics is strengthened.
Preferably, the cutting teeth quantity of installing on described wing is 4, and the first impregnated post quantity is 26, and the second impregnated post quantity is 24, and the 3rd impregnated post quantity is 16.
As further technical scheme of the present utility model, described cutting teeth is distributed in the center of wing.
As further technical scheme of the present utility model, the structure of described the first impregnated post, the second impregnated post and the 3rd impregnated post is a kind of in cylindrical, oblate spheroid capitiform, track type, square or wedge shape.
As further technical scheme of the present utility model, described the first impregnated post is track type, and the second impregnated post is oblate spheroid capitiform, and the 3rd impregnated post is cylindrical.
Compared to existing technology, the beneficial effects of the utility model are: reasonable in design, adopt split type impregnated cutting structure to replace the impregnated cutting structure of original monolithic, the impregnated post of different structure is alternately distributed the cutter set density that can further increase structure, can strengthen the efficiency of breaking rock of cutting dynamics and diamond-impregnated bit, and anti-wear performance is good, not fragile, can extend application life of drill bit.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
