Abstract
The utility model discloses a button impregnated diamond bit which is provided with a cylinder like basal body which is provided with an inner screw thread connected with a drill stem, the superior part of the cylinder like basal body is welded with a plurality of moles which are alloy bumps, a plurality of buttons form on the top of each alloy bump, the buttons are internally enchased with diamond particles, the interior and exterior of each bump are impregnated with diamond polycrystalline strips for protecting diameter so that the wear resistance of the bumps are not high, thereby making the diamonds in the buttons exposed and advance in hard and compact red feldspar granite stratum. The utility model has a drilling speed of 1.52 to 1.80 m/h and a service life of 34.40 to 36.10m, thereby speeding up the drilling and preventing the phenomena of skidding and penetration absence.
Description
Technical field
The utility model relates to a kind of geological drilling drill bit, particularly a kind of ball tooth diamond-impregnated bit.
Background technology
At present, diamond probing technology is occupied main status in China core drilling field, and is special.Artificial pregnantly launched in each borehole engineering field by the application of diamond bit, it is good to have hole quality, the efficient height, wide accommodation, low cost and other advantages, and the structure of existing artificial diamond-impregnated bit is, it is a tubular drill bit, its underpart is the tubular matrix, this tubular matrix has the internal thread that is connected with drilling rod, the top welding of tubular matrix has mole, this mole is an alloy bump, and impregnated in the top of this alloy bump have a diamond, because, the top of this mole is plane, abrasivenesses a little less than some, creeping in the tight formation, exist the drill bit not phenomenon of drilling depth of " skidding ", is a needs problem demanding prompt solution.
Summary of the invention
The purpose of this utility model is in order to solve existing artificial pregnantly crept in weak abrasiveness, tight formation by diamond bit, and the drill slipping of existence is the problem of drilling depth not, and a kind of ball tooth diamond-impregnated bit that overcomes above-mentioned shortcoming is provided.
Structure of the present utility model is, has a tubular matrix, this tubular matrix has the internal thread that is connected with drilling rod, the top welding of this tubular matrix has several moles, this mole is an alloy bump, the top of each alloy bump is formed with several ball teeth, the interior impregnated diamond particles that has of this ball tooth, the impregnated footpath dimond synneusis bar that protects of the inside and outside wall of mole, because of the abrasion resistance of the alloy that forms this mole is not high, in the process that probing is used, can guarantee the diamond particles exposure in the ball tooth, improve rate of penetration, prevented the generation of skidding.
The utility model artificial is pregnantly compared by diamond bit with common, and advantage is as follows:
For example, creep in the red potassic feldspar granitic formation of hard and compact, common artificial diamond-impregnated bit rate of penetration is 0.2～0.3m/h only, presents skidding; And rate of penetration of the present utility model is 1.52～1.80m/h, and the life-span reaches 34.40～36.10m/, and the utility model has solved that common artificial diamond-impregnated bit exists when creeping into skids, drilling depth problem not, has improved rate of penetration and application life.
Description of drawings
Fig. 1 is the vertical view of the utility model embodiment.
Fig. 2 is that A-A among Fig. 1 is to sectional view.
The specific embodiment
See also Fig. 1, shown in Figure 2, structure of the present utility model is, has a tubular matrix 1, this tubular matrix 1 has the internal thread 2 that is connected with drilling rod, the top welding of this tubular matrix 1 has eight moles 3, this mole is an alloy bump, the top of each alloy bump is formed with five ball teeth 4, impregnated in this ball tooth 4 have diamond particles, and the inside and outside wall of mole is impregnated to protect the footpath with dimond synneusis bar 5, because of the abrasion resistance of the alloy that forms this mole 3 not high, in the process that probing is used, can guarantee the diamond particles exposure in the ball tooth 4, improve rate of penetration, prevent the generation of skidding.
Claims (1)
1, a kind of ball tooth diamond-impregnated bit, it has a tubular matrix, this tubular matrix has the internal thread that is connected with drilling rod, the top welding of this tubular matrix has several moles, this mole is an alloy bump, the dimond synneusis bar is used in the impregnated footpath of protecting of the inside and outside wall of mole, and it is characterized in that: the top of each alloy bump is formed with several ball teeth, the interior impregnated diamond particles that has of this ball tooth.
