Description
Technical field
This utility model is related to petroleum gas PDC drill bit technical field, and in particular to a kind of ONYX360 ° of rotation PDC is bored
The inside and outside row's cutting tooth linkage of head.
Background technology
In oil and gas well drilling operation, grind formation rock by drill bit to be drilled to the interface channel of oil gas, the passage
It is referred to as well, the connection on ground and underground oil and gas resource is realized by well, so as to underground oil and gas resource is produced ground.Its
In, drill bit is the instrument that direct fractured rock forms well, and the performance of drill bit can directly affect bit speed.Drill bit is by structure point
For drag bit, rifler, four big class of diamond bit and core bit.Wherein, polycrystalline diamond compact bit
(Polycrystalline Diamond Compact Bits) is called PDC drill bit for short, is one kind of diamond bit, passes through
The cutting tooth that PDC drill bit surface is fixed carrys out fractured rock, and the main component of cutting tooth is composite polycrystal-diamond, special because of which
Constituent, fractured rock efficiency are higher, therefore, PDC drill bit has outstanding performance and advantage, and at present, PDC drill bit is in the world
Drill footage ratio in oil/gas drilling market oneself up to drilling well total footage 90% or so.
At present, with the reduction of petroleum resources, the environment of drilling well constantly deteriorates constantly to be deepened with drilling depth, with drilling well
The intensification of depth, the rock strength and abrasiveness of underground are consequently increased, in drilling process, the cutting odontotripsis journey of PDC drill bit
Degree is more serious, and the efficiency of fractured rock declines obvious, PDC drill bit use time reduction, so as to reduce rate of penetration, increases
Drilling cost.With the increase and the deterioration of drilling environment of drilling depth, higher requirement is proposed to drill bit, especially to making
The great PDC drill bit of consumption is put forward higher requirement.
Smith's drill bit company (Smith Bits) is the display drivers of Schlumberger of international oil gas service provider, closely
Phase develops the rotation PDC cutting tooths of ONYX 360, is one kind of PDC drill bit, is characterized in fix original PDC drill bit surface
Cutting tooth changes into rotatable cutting tooth, and this change improves the service life of drill bit.Because in drilling process, original
The cutting tooth of PDC drill bit is fixed, and an only cutting tooth part is contacted with formation rock, is worn and torn more serious.360 ° of rotations of ONYX
The characteristics of turning PDC drill bit is cutting tooth rotatable rotation while fractured rock on its surface, the change cause cutting tooth with
All surfaces around the part cutting tooth of formation rock contact, then greatly reduce the cutting tooth degree of wear.The drill bit
The cutting tooth of surface design has outer row's cutting tooth and interior row's cutting tooth, and the anticipation of design is, in drilling process, inside and outside row cuts
Cut when tooth is contacted with formation rock and all rotate with the rotation of drill bit, however, in drilling well actual application, outer row's cutting
Tooth can be rotated, and interior row's cutting tooth is not rotated because inside and outside cutting tooth all can be contacted with formation rock, outer row's cutting tooth away from
The distance of bit central is big, and linear velocity is larger, and outer row's cutting tooth can rotate, and interior row's cutting tooth is nearer away from bit central position,
Linear velocity is less, it is impossible to rotate so that interior row's cutter-wear rate is larger so that the service life of drill bit is reduced.It is same to drop
Low bit speed.
Analyze based on more than, this utility model devises row's cutting tooth linkage inside and outside ONYX360 ° of rotation PDC drill bit,
It is intended to original static interior row's cutting tooth is transformed into rotary state by resting state by the device, improves interior row's cutting tooth
Service life, reaches the effect for improving footage per bit and drilling life of bit, realizes improving bit speed and reduces drilling cost
Purpose.Wherein during bit cutting stratum, outer row's cutting tooth is revolved around power transmission shaft while revolving round the sun around drill bit
Turn, this device with the addition of 4 class travelling gears in inside and outside row cutting between cog, it is respectively outer row's travelling gear, outer row's idler gear, interior
Row's travelling gear, interior row's idler gear.Outer row's cutting tooth is connected with outer row's travelling gear by power transmission shaft, outer row's travelling gear Jing
Cross outer row's idler gear to be connected with interior row's travelling gear, interior row's travelling gear is connected simultaneously with interior row's cutting tooth and interior row's idler gear
Connect, interior row's idler gear be connected with row's travelling gear in another, interior row's travelling gear connect again with another in arrange cutting tooth
Connection, circulation internal ring one week, so that realize the gearing of inside and outside row's cutting tooth.
Utility model content
The purpose of this utility model is to provide a kind of linkage for arranging cutting tooth inside and outside ONYX360 ° of rotation PDC drill bit
With method, so that the realization during cutting stratum of interior row's cutting tooth is effectively rotated, the use longevity of cutting tooth in raising, is arranged
Life, reaches the effect for improving footage per bit and drilling life of bit, realizes improving bit speed and reduces drilling cost.
In order to achieve the above object, this utility model is adopted the following technical scheme that：
A kind of inside and outside row's cutting tooth linkage of ONYX360 ° of rotation PDC drill bit is mainly by outer row's cutting tooth, power transmission shaft, outer
Row's travelling gear, outer row's idler gear, interior row's travelling gear, interior row's idler gear, interior row's cutting tooth, groove composition；Outer row cuts
