Description
The cross reference of related application
This application claims being filed in U.S. Provisional Patent Application No.61/992 on May 13rd, 2014,654 priority,
This temporary patent application is incorporated by reference in its entirety herein.
Technical field
The present invention relates to rotary drilling-head.More particularly, it relates to complete infiltration type rotary drilling-head.
Background technology
Rotary drilling-head is widely used in boring or the drilling well of subsurface boring.There are perhaps eurypalynous rig and related side
Method is used for this kind of probing.Common probing is using the rotary drilling-head being attached to drill string one end.Rotary drilling-head generally includes and is fixed on
Multiple cutting elements in drill main body surface region.Drill string includes managing and is connected to for will be located into the drill bit of foot of hole
The equipment section of other drilling equipments in earth's surface.The brill in drill string and boring can be rotated using rotation platform or top drive
Head.In addition, the shank of drill bit can be directly coupled in the drive shaft of downhole electrical motor, downhole electrical motor subsequently can be used for rotating boring
Head.
Rotary drilling-head, particularly on the cutting end being covered with cutting element, usually plate-like or substantially cylindrical.Often
The cutting surface that individual cutting element all has generally is made up of hard ultrawear-resistant material (such as polycrystalline diamond), the end face of element
It is usually the form of circular, such element is commonly known as " polycrystalline diamond composite material " (PDC) cutter.Have many
As species, drill bit form is available；However, cutting element is generally manufactured respectively with drill main body, it is then fitted into being formed at
In the groove of drill main body outer surface.Cutting element can be fixed by any suitable means, for example, by using the material that bonds
Material, including various binding agents, or more generally, various brazing alloys.Drill main body is fixed on American Petroleum Institute (API)
(API) in threaded hardening steel handle, for drill bit is attached to drill string.During use, cutting element and its cutting surface
Contact with stratum to be drilled.During bit, cutting element is gradually pruned the surface of underlying strata, thus forming boring.
The drill main body of rotary drilling-head can be formed by steel；However, this kind of drill main body can wear and tear, the speed meeting of abrasion
There is obvious difference according to the difference of drilling environment.Wear and tear to reduce and increase the service life, drill main body also uses
Particle matrix composite makes.
The drill main body of particle matrix composite is first made with the graphite jig with processing cavity.Can be by hand-held work
Tool, adds other fine-feature structures in the chamber of graphite jig.It is also possible to use and be made up of sand, clay or other materials
Insert or core are obtaining some preferable drill main body latent structures.(can be by if it is necessary, preform elements or replacing part
Any suitable material is made, including ceramic component, graphite member or the fine and close sand part with resin-coating) can be positioned on mould
Tool in and be used for limiting various features structure, including inner passage, cutting element groove, chip area and drill main body other outside
Portion's configuration or internal feature structure.The chamber of graphite jig is filled with carbide material (the such as tungsten carbide, carbonization of hard particles shape
Titanium, ramet etc.).Subsequently by preformation shaped blooms at an appropriate location with orientation positions in mould, this steel billet typically at least part
Sink in the particulate carbide material in mould.
Subsequently can swing die or by granule compress to improve the packed density of carbide powder and to form powder type.Will
Host material (such as acid bronze alloy) melts and is incorporated in carbide powder so that the host material of melting penetrates into powder shape
In formula.Mould and drill main body can be cooled down, so that host material solidifies and steel billet is connected to particle matrix composite
Upper formation bizet.Mould and all refill-units are removed from drill main body.Remove and during drill main body, typically require destruction graphite mo(u)ld
Tool.
Once drill main body removes from described mould, will be fixed on for a long time in steel handle.Can lead on the surface of steel billet
Over mechanical processing forms thread forms, threaded to provide between drill main body and steel handle.
Although steel billet can provide generally acceptable connection steel handle and the mode of drill main body, in mould during infiltration
Base can shift, lead to base cannot align with drill main body, thus resulting in drill main body cannot use, or needs to drill bit
Main body carries out extra processing or other are done over again.In addition, introduce base to need first it to be entered before infiltration as extra part
Row decontamination or cleaning, to guarantee the metallurgical binding between base and metal matrix.In addition, the material according to used by base, base and
Interaction between host material may result in the formation of both interface phases, and can thus lead to during using drill bit
The formation in crack and expansion.
Although the drill main body containing particle matrix composite compared to all steel drill main body wear-resistant and corrosion
Aspect has obvious advantage, but the low-intensity of such drill main body and soft limit their fortune in some application-specific
With.Improve hardness, intensity or other properties of these particle matrix composites, just can expand the application model of this kind of drill main body
Enclose.
