Description
Technical field
The utility model belongs to oil bit field, specifically, relates to the Mixed drilling bit of a kind of triangular polycrystalline diamond and impregnated tooth.
Background technology
In petroleum geology exploration exploitation, it is PDC and rock bit that drill bit adopted more, better for soft-medium ground at present, be used for firmly with overlying strata, use stratum wide, but working effect be poor, cause occurring that drilling cost raises, for producing and exploration brings many problems.
In addition, existing drill bit is the drill bit of simple function, and the geological conditions of adaptation is few, affects the scope of application of drill bit, and after running into the rock stratum that the hardness such as granite are high, can cause drill bit heavy wear, even scraps.
Utility model content
For solving the problem in background technology, the utility model provides the Mixed drilling bit of a kind of triangular polycrystalline diamond reasonable in design, applied widely and impregnated tooth.
The technical solution of the utility model is:
A Mixed drilling bit for triangular polycrystalline diamond 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 triangular polycrystalline diamond teeth 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 by carcass.
As a kind of technical scheme of optimization, the number of described wing is even number, is separately installed with some triangular polycrystalline diamond teeth 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 various shape.
As a kind of technical scheme of optimization, described triangular polycrystalline diamond tooth is the some plow crushing teeths that are embedded on wing, and triangular polycrystalline diamond tooth is made by diamond.
As a kind of technical scheme of optimization, the number of described wing is six, and wherein impregnated tooth and triangular polycrystalline diamond are set in respectively on corresponding wing.
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 triangular polycrystalline diamond tooth and impregnated tooth are set respectively on adjacent wing, impregnated tooth has splendid grinding function, triangular polycrystalline diamond tooth is to be made by diamond, there is splendid plow ability, guaranteed that drill bit is useful in firmly-competent bed, carcass has excellent impact resistance and toughness, can guarantee the application life of drill bit, be suitable for promoting the use of.
Accompanying drawing explanation
Fig. 1 is the structural representation of overlooking of a kind of embodiment of the utility model.
