Description
Technical field
The present invention relates to it is a kind of suitable for oil and gas well drilling can detachable type PDC re-drill bits.
Background technology
As the secondary development of casing window sidetracking and old well is more and more, PDC re-drill bits are widely applied.By
It is big in the reaming hole body size of re-drill bit, limited by agglomerating plant, it is impossible to using pressureless impregnation sintering process, and use steel body
Direct processing and forming technology.
With the development of CNC technologies and the constantly improve of processing technology, it can be achieved that the steel body type re-drill bits of more specifications
Production, but there is steel body type re-drill bit generally use entirety Milling Process, wing is machined in one mostly with drill body,
The process-cycle length of drill bit, processing capacity are big.Therefore, can be produced in batches there is an urgent need to one kind in the prior art, quick assembling and dismantling, system
Cause this it is low can detachable type PDC re-drill bits.
The content of the invention
It is an object of the invention to provide it is a kind of can solve the above-mentioned problems in the prior art can detachable type PDC
Re-drill bit.
The technical scheme is that：It is described can detachable type PDC re-drill bits by drill body, soket head cap screw, knife
The wing, gauge teeth, cutting tooth and nozzle composition；The drill body and wing is steel body；Drill body front end circumferencial direction
Be uniformly distributed 6 grooves, inside each groove on cylindrical surface process a T-shaped boss, drill body rear end for taper thread with
Well dynamic instrument connects；Gauge teeth and cutting tooth are provided with outside the wing, inside sets T-shaped groove；During installation, knife
The wing is coordinated by T-slot and the T-shaped boss of drill body to be realized circumferentially positioned, and wing is fixed on brill using soket head cap screw
Axially position is realized on head body, nozzle is installed in the nozzle threads hole between two wing of drill body front end.The present invention's
Can detachable type PDC re-drill bits it is easy to process, the maintenance speed of drill bit is fast, and in shaft bottom, usual wing is easiest to bad, it is only necessary to
The wing of live more bit change, while cost-effective, improves the efficiency of drilling well.
Described in such scheme can detachable type PDC re-drill bits, it is characterised in that：The PDC re-drill bits are 6 knives
During the wing, drill body front end circumferencial direction is uniformly distributed 6 grooves, and it is convex that a T-shaped is processed inside each groove on cylindrical surface
Platform；For 5 wing PDC re-drill bits, 5 grooves can be uniformly distributed in drill body front end circumferencial direction.
Described in such scheme can detachable type PDC re-drill bits, the T of processing inside each groove of the drill body
Shape boss, is threaded hole T-shaped boss rear portion is oblique；Cambered surface center oblique processing of the wing in welding gauge teeth
One stepped hole, it is possible to achieve coordinated by soket head cap screw through stepped hole and threaded hole, wing is fixed on drill body
On；The gauge teeth and cutting tooth are installed on wing all by way of inlaying, welding.
Described in such scheme can detachable type PDC re-drill bits, the drill body and wing use separate machined
The mode reassembled produces.Since what is destroyed at first in the usual drill bit in shaft bottom is wing, so the wing is used than drill bit
The material of bulk strength higher, extend can detachable type PDC re-drill bits service life, while save the material of drill bit.
Described in such scheme can detachable type PDC re-drill bits, the wing can be processed into different model, can be with
In the case where ensureing that drill body is constant, the model of wing is replaced to change the work outside diameter of drill bit, so as to change reaming hole well
Size.
The beneficial effects of the invention are as follows：(1) drill body, wing can carry out batch system as the assembling standard component of drill bit
Make, the drill produced cycle is short, and manufacture cost is low；(2) wing can fast be mounted and dismounted with drill body, the wing of different size
Assembling with drill body is, it can be achieved that the reaming of different size wellbore；（3）Can detachable type PDC re-drill bits drill body and
Wing separate machined, selects different material, can save precious materials；（4）The present invention can be needed only more in situ of drilling well
The wing of bit change, saves the cost of purchase drill bit.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
Referring to attached drawing, it is described can detachable type PDC re-drill bits include drill body 1, soket head cap screw 2, wing 3, protect
Footpath tooth 4, cutting tooth 5 and nozzle 6；The drill body 1 and wing 3 is steel body；1 front end circumferencial direction of drill body is uniform
6 grooves are distributed, a T-shaped boss are processed inside each groove on cylindrical surface, 1 rear end of drill body is taper thread and underground
Power tool connects；Gauge teeth 4 and cutting tooth 5 are provided with outside the wing 3, inside sets T-shaped groove；During installation, knife
The wing 3 is coordinated by the T-shaped boss of T-slot and drill body 1 to be realized circumferentially positioned, and is fixed wing 3 using soket head cap screw 2
Axially position is realized on drill body 1, nozzle 6 is installed in the nozzle threads hole between 1 front end of drill body, two wing 3.
The present invention can detachable type PDC re-drill bits it is easy to process, the maintenance speed of drill bit is fast, and in shaft bottom, usual wing is easiest to damage
It is bad, it is only necessary to which that the wing 3 of more bit change at the scene, while cost-effective, improves the efficiency of drilling well.
When the PDC re-drill bits are 6 wing, 1 front end circumferencial direction of drill body is uniformly distributed 6 grooves, in circle
One T-shaped boss of processing inside each groove of cylinder；For 5 wing PDC re-drill bits, can justify in 1 front end of drill body
Circumferential direction is uniformly distributed 5 grooves；The T-shaped boss of processing inside 1 each groove of drill body, at T-shaped boss rear portion
It is oblique to be threaded hole 7；The wing 3, can be with one stepped hole 8 of the oblique processing in cambered surface center of welding gauge teeth 4
Realization is coordinated by soket head cap screw 2 through stepped hole 8 with threaded hole 7, and wing 3 is fixed on drill body 1.
The gauge teeth 4 and cutting tooth 5 are installed on wing 3 all by way of inlaying, welding；The drill bit sheet
Body 1 and wing 3 produce by the way of separate machined reassembles.Since what is destroyed at first in the usual drill bit in shaft bottom is wing, institute
With the wing 3 using the material than 1 intensity higher of drill body, extend can detachable type PDC re-drill bits service life,
The material of drill bit is saved at the same time.
The wing 3 can be processed into different model, can be in the case where ensureing that drill body 1 is constant, more tool changing
The model of the wing 3 changes the work outside diameter of drill bit, so as to change the size of reaming hole well.
