Abstract
The utility model discloses a multifunction diamond inserted tooth protection composite sheet drilling bit, which comprises a blade, a water hole and a water channel. The blade is provided with a polycrystalline diamond composite sheet, and also provided with a multifunction diamond inserted tooth. The multifunction diamond inserted tooth and the drill bit form an integrated structure. The multifunction diamond inserted tooth can be arranged at the top or backside of the polycrystalline diamond composite sheet on a radius retention part ranging from 20cm to 30cm. The multifunction diamond inserted tooth protection composite sheet drilling bit not only has full damping but also has wear resistance, and long service life.
Description
Technical field
The utility model relates to the rotary drilling drill bit that a kind of oil, geology are used, particularly a kind of multi-functional diamond cast tooth protection compact bit.
Background technology
At present, use is very extensive as cutting teeth with diamond PDC (polycrystalline diamond) in the rotary drilling in fields such as oil, geology, the polycrystalline diamond of welding-on will bear very complicated power on the drill bit in well, its vibration, impact and to bump wound very frequent, polycrystalline diamond itself belongs to fragile material in addition, is easy to be damaged, particularly at the top of wing or protect the position, footpath, polycrystalline diamond is easier to be impaired, has a strong impact on the efficient of drill bit.
The utility model content
At the shortcoming that above-mentioned prior art exists, the utility model provides a kind of multi-functional diamond cast tooth protection compact bit, and this drill bit vibration damping is abundant, wear-resistant, long service life.
The technical solution adopted in the utility model is: a kind of multi-functional diamond cast tooth protection compact bit; comprise wing, hydrophthalmia, water channel; wing is provided with composite polycrystal-diamond, also is provided with multi-functional impregnated tooth on wing, and this multi-functional impregnated tooth and drill bit are into a single integrated structure.
Described multi-functional impregnated tooth can be arranged on the top or protect the back of the composite polycrystal-diamond at place, footpath, can be arranged on 20-30mm place behind the composite polycrystal-diamond.
Described multi-functional impregnated tooth can be disposed according to a certain percentage to fire and form by diamond and corresponding metal powder.
Described impregnated tooth can be sphere, is fired by high-quality natural diamond and tungsten carbide powder to form; Described impregnated tooth can be plates, is fired by artificial single crystal's diamond and tungsten carbide powder to form; Described impregnated tooth can be for cylindrical, fired by needle-like polycrystalline diamond and tungsten carbide powder to form; Described impregnated tooth can be wedge shape, is mixed by triangle polycrystalline diamond and the preparation of tungsten carbide powder.
The utility model is because wing is provided with multi-functional impregnated tooth; multi-functional impregnated tooth is positioned at the back of polycrystalline diamond; because the hardness and the abrasion resistance performance of multi-functional impregnated tooth are all relatively good; on harder or irregular stratum; multi-functional impregnated tooth can play the effect of good vibration damping, protection to composite polycrystal-diamond, thereby prolongs the application life of drill bit.
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Description of drawings
Fig. 1 is a sectional schematic diagram of the present utility model;
Fig. 2 position partial schematic diagram of the present utility model.
The specific embodiment
As Fig. 1, shown in Figure 2, the wing 1 that includes of the present utility model, water channel 2, hydrophthalmia 3, wing 1 are provided with composite polycrystal-diamond 4, be provided with multi-functional impregnated tooth 5 in the back that is positioned at the top or protects the composite polycrystal-diamond at place, footpath, multi-functional impregnated tooth 5 is positioned at about 24-30mmc place behind the composite polycrystal-diamond.Multi-functional impregnated tooth 5 is into a single integrated structure with wing 1, can be when making one fire and form, also can be welded on the cutter Ji 1.
Described multi-functional impregnated tooth can be to be prepared according to a certain percentage by natural diamond, artificial single crystal's diamond and any polycrystalline diamond and corresponding carbide powder, perhaps polycrystalline diamond is arranged in the metal dust by certain way.
Described multi-functional impregnated tooth can be multiple shape, can be spheroidal, fire by high-quality natural diamond and tungsten carbide powder and to form, can be plates, form by artificial single crystal's diamond and tungsten carbide powder, can be for cylindrical, fire by needle-like polycrystalline diamond and tungsten carbide powder and to form, can be wedge shape, form, can also be shapes such as taper shape, rectangle by triangle polycrystalline diamond and tungsten carbide powder mixed sintering.
