Abstract
The utility model has been announced the Mixed drilling bit of a kind of composite sheet and impregnated tooth, comprises joint pin and bit body, it is characterized in that: on described bit body, be symmetrically arranged with some wings, be respectively arranged with some composite sheet and some impregnated tooths on wing; On described bit body, between wing, be provided with some hole for water sprayings; Described bit body and wing are all made up of carcass.Bit body of the present utility model and wing are manufactured by carcass Integral design, and impregnated tooth and composite sheet are set respectively on adjacent wing, impregnated tooth has splendid grinding function, composite sheet has splendid cutting function, ensure the applied widely of drill bit, carcass has impact resistance and toughness, can ensure the application life of drill bit, is suitable for the staggered stratum of soft or hard.
Description
Technical field
The utility model belongs to oil bit field, specifically, relates to the Mixed drilling bit of a kind of composite sheet and impregnated tooth.
Background technology
In geological prospecting exploitation, in petroleum drilling and mining, the quality of the performance of drill bit has directly determined the year drilling depth quantity of drill footage at present.But it is the broken rock drill bit of simple function that current oil bit adopted more, encounters soft or hard crossbeding, simple function drill bit cannot adapt to, cause can drilling process in bit change more repeatedly, affect rate of penetration, cost rising, in addition, the drill bit of simple function, the stratum scope of adaptation is few.
Utility model content
For solving the problem in background technology, the utility model provide a kind of reasonable in design, be suitable for creeping into the staggered composite sheet on stratum of soft or hard and the Mixed drilling bit of impregnated tooth.
The technical solution of the utility model is:
A Mixed drilling bit for composite sheet and impregnated tooth, comprises joint pin and bit body, it is characterized in that: on described bit body, be symmetrically arranged with some wings, be respectively arranged with some composite sheet and some impregnated tooths on wing; On described bit body, between wing, be provided with some hole for water sprayings; Described bit body and wing are all made up of carcass.
As a kind of technical scheme of optimization, the number of described wing is even number, is separately installed with some composite sheet and some impregnated tooths on adjacent wing.
As a kind of technical scheme of optimization, described impregnated tooth comprises tooth post and crown, and described crown comprises that being arranged on tooth post upper end can be designed to circle, wedge shape, sharp-tooth shaped.
As a kind of technical scheme of optimization, the multiple that the number of described wing is 2, wherein composite sheet is distributed on corresponding wing with impregnated tooth.
Owing to having adopted technique scheme, compared with prior art, bit body of the present utility model and wing are manufactured by carcass Integral design, and impregnated tooth and composite sheet are set respectively on adjacent wing, and impregnated tooth has splendid grinding function, and composite sheet has splendid cutting function, ensure the applied widely of drill bit, the impact resistance that carcass has and toughness, can ensure application life of drill bit, is suitable for the staggered stratum of soft or hard.
Brief description of the drawings
Fig. 1 is the structural representation of overlooking of a kind of embodiment of the utility model.
Detailed description of the invention
Embodiment
As shown in Figure 1, the Mixed drilling bit of a kind of composite sheet and impregnated tooth, comprises joint pin and bit body 1, is symmetrically arranged with some wings 5 on described bit body 1, is respectively arranged with some composite sheet 2 or some impregnated tooths 3 on wing 5.On described bit body 1, between wing 5, be provided with some hole for water sprayings 4.Described bit body 1 and wing 5 are all made up of carcass.
In the present embodiment, the number of described wing 5 is even number, is separately installed with some composite sheet 2 and some impregnated tooths 3 on adjacent wing 5.
Described impregnated tooth 3 comprises tooth post and crown, and the shape of crown can have multiple setting, often can be designed to the shapes such as circular arc, spheroidal, wedge shape, pointed tooth.
Consider actual use, the multiple that the number of described wing 5 is 2, wherein impregnated tooth and composite sheet are arranged on corresponding wing.
Bit body of the present utility model and wing are by carcass Integral design, and impregnated tooth and composite sheet are set respectively on adjacent wing, impregnated tooth has splendid grinding function, composite sheet has splendid cutting function, ensure the applied widely of drill bit, carcass has impact resistance and toughness, can ensure the application life of drill bit, is suitable for the staggered stratum of soft or hard.
The utility model is not limited to above-mentioned preferred embodiment, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or akin technical scheme, all belong to protection domain of the present utility model.
