Description
Technical field
The present invention relates to oil equipment fields, more particularly to a kind of polycrystalline diamond compact bit.In addition, of the invention
Further relate to a kind of oil-well drilling equipment with the drill bit.
Background technique
Polycrystalline diamond compact bit (PDC drill bit) is using the composite polycrystal-diamond with extreme hardness as brill
The cutting tooth of head has very high efficiency of breaking rock and rate of penetration, is currently the drill bit that field of oil drilling is most widely used
Tool.PDC drill bit steel body connector and matrix crown two parts are made carcass using the powder sintered method of diamondite and are preced with
Portion, it is then whole to drill bit is welded into steel body connector.
Since steel body connector and matrix crown are split settings, need to solve the problems, such as connection and sealing, the prior art
Under, the mode of threaded connection is usually used, is then again by welding welded junction gap, guarantees steel body connector
Firm be tightly connected is formed between matrix crown.And there are an apparent defects, i.e. drill bit and screw drill for threaded connection
For tool in underground work, rotation mode is exactly to rotate in a circumferential direction, and the connection type of steel body connector and matrix crown is also circumferential spiral shell
Line connection type is easy for that matrix crown is caused to cause to loosen even because of small torsion under the adverse circumstances of high pressure HI high impact
The problem of falling well.Although there are also welding layers between steel body connector and matrix crown, since layer is shallow on gap surface layer
Real metallurgical bonding is not realized in shallow welding, along with underground working is extremely severe, serious wear, after being worn away
Connection effect is weak.
Meanwhile diamondite hardness is very high, carry out screw thread process be it is very difficult, manufactured by 3D printing technique
When matrix crown, although the shape of screw thread can be printed, 3D printing can not directly print the spiral shell for meeting required precision
Line needs that high precision screw could be obtained by machining.But due to the brittleness of carcass material itself, the screw thread is unbearable
Too big pulling force ultimately causes matrix crown thread failure.
Therefore, how a kind of stable delivery torque and pulling force are provided, the polycrystalline diamond of stability and mechanical performance is improved
Compact bit is a technical problem that technical personnel in the field need to solve at present.

It is more, it can save material in this way, reduce production cost, and the high intensity and steel body connector 1 for the matrix crown 2 that can get both simultaneously
High tenacity, promote the whole impact resistance and mechanical performance of bit body, extend drilling life of bit, improve drilling crew's drilling effect
Rate.Hot-forming matrix crown can also be used, be also possible to split type steel body bizet, can use above-mentioned connection type
Connection.
On the basis of the polycrystalline diamond compact bit that above-mentioned each specific embodiment provides, the end of locating piece 3
It is welded with the external port of outer location hole 12, molten metal sealant is provided between rear end face and front end face.Wherein, molten metal
Sealant can be brazing layer, i.e., be cooled into after being melted by the soldering item melted.
Specific processing method are as follows: use 3D printing increases material manufacturing technology, print matrix crown 2, six sides of link block 21
Shape outer wall plane and end face can suitably polishs using flat stone mill, and for interior location hole 22 without individually processing, when 3D printing is straight
It is connected into type.
Process the matrix of steel body connector 1 using mach mode, front end extend wing 13, link slot 11 interior six
Square inner wall plane and end face are suitably polished using grinding, and outer 12 size of location hole is consistent with interior 22 size of location hole.
The rear end face of matrix crown 2 is covered with welding rod, the soldering for subsequent matrix crown 2 and steel body connector 1 is prepared.
In the way of induction heating, at the top of steel body connector 1 is heated, because the thermal expansion coefficient of steel is good, after heating
Steel body connector 1 has certain expansion, and using the principle of hot insert, the matrix crown 2 for being covered with welding rod is pressed into steel body connector 1, and
It is inserted into pin, then welds the external port of the end of pin and outer location hole 12.
The steel body connector 1 connected and matrix crown 2 are brazed again, the welding rod between front end face and rear end face
Sufficiently after melting, brazing layer is formed, the gap between drill bit 2 and steel body connector 1 is finally made to realize that firm sealing connects
It connects.It can be brazed by the way of electromagnetic induction heating, principle of heating is the electromagnetic induction effect by coil, so that
Steel body part heating within the scope of the coil line of magnetic induction, other parts will not heat, and when facilitating control heating region and heating
Between, compared with other brazing modes, aforesaid way apply drill bit soldering field it is more convenient, the side of furnace brazing can also be used
Formula, as long as enabling to the welding rod of end face sufficiently to melt and realizing the metallurgical bonding of end face.Certainly it can also be used mechanical close
Envelope mode, figure suit sealing ring or sealing ring etc..
In addition to above-mentioned polycrystalline diamond compact bit, it includes above-mentioned brill that a specific embodiment of the invention, which also provides a kind of,
The oil-well drilling equipment of head, refer to the prior art for the structure of other each sections of the oil-well drilling equipment, and repeats no more herein.
