Background technique
PDC drill bit and diamond bit in petroleum and geological drilling using more and more extensive, in soft formation or hard formation
The middle using effect and good economic benefit that can have been obtained, the extensive attention by petroleum circle and geology circle.Conventional PDC drill bit
Design with diamond bit is bored with corona shapes such as bipyramids as passive anti-oblique technology using deep, is answered using balanced design as principle
It uses among design, plays the role of certain certralizing ability and hold angle.Currently, PDC drill bit is mainly by bit body (carcass), PDC
The composition such as cutting tooth, apopore, gauge material and connector cuts stratum by PDC cutting tooth to realize drilling, the water outlet
Hole is drill bit inner cavity and external water passage, and apopore main function is bottom-hole cleaning, and clast is taken away shaft bottom, prevents drill bit
Mud drum reduces Repeated Cutting, improves efficiency of breaking rock, and in addition there are also hydraulic drillings to act under certain drilling parameter.It is high when work
The bit body of speed rotation drives PDC cutting tooth high-speed rotation, and PDC cutting tooth cuts soft formation or hard formation.
However, when PDC drill bit is when creeping into soft formation, the accumulation of cutting object easy to form, i.e. dope in PDC cutting tooth
PDC cutting tooth is wrapped, causes PDC cutting tooth that cannot smoothly creep into soft formation, to reduce the efficiency of drilling well.When PDC is bored
Head when creeping into hard formation, firm rock be drilled it is broken after, a large amount of graininess clast is generated, although clast will not wrap
PDC cutting tooth, but clast is largely deposited on shaft bottom, causes fluid to be difficult to for clast being discharged from hoistway, and chip removal efficiency is slow, into
One step reduces efficiency of breaking rock.

Specific embodiment
The present invention will be further described with reference to the accompanying drawing, and protection scope of the present invention is not limited to as described below:
As shown in Fig. 1 ~ 3, one kind being used for bad ground dual vector nozzle PDC drill bit, it includes bit body 1, the bit body 1
Inside offer fluid chamber 2, the bottom of bit body 1 is provided with bizet 3, on the bottom surface of the bizet 3 and along the circle of bit body 1
Circumferential direction is installed with multiple operator wings 4, and in the present embodiment, the operator wing 4 is uniformly distributed on bizet 3, operates on the wing 4 and edge
Its length direction is installed with multiple PDC cutting tooths 5, one is offered on the bottom surface of the bizet 3 irises out the mouth of a river 6 and one and iris out water
Hole 7, water outlet 6 are located at 7 outside of apopore, are provided with dual vector nozzle 8 at each water outlet 6.
The dual vector nozzle 8 includes motor 9, rack A10, rack B11, jet pipe 12, cable 18 and is fixedly arranged on out
The pipe fitting A13 of 6 bottom of the mouth of a river, rack A10 and rack B11 are welded on the bottom surface of bizet 3 and are located at the two of water outlet 6
Side, jet pipe 12 are welded with shaft 14, two shafts 14 between rack A10 and rack B11 on the outer wall of 12 two sides of jet pipe
Rotation is installed on rack A10 and rack B11 respectively, and motor 9 is set to rack A10 on and the output shaft of motor 9 and shaft 14
It is connected through shaft coupling, pipe fitting B15 is connected at the top of jet pipe 12, hose 16 is connected between pipe fitting B15 and pipe fitting A13,
One end of the cable 18 is through fluid chamber 2, water outlet 6, pipe fitting A13, hose 16, pipe fitting B15 and defeated with motor 9
Inbound port connection, the other end of cable 18 are connect with the output port of ground PLC controller.
The water discharging direction of the apopore 7 and the cutting direction of PDC cutting tooth 5 are on the contrary, when being passed through height into fluid chamber 2
After pressing fluid, high-pressure fluid is ejected from apopore 7, form torque, that is, it is certain that the fluid projected gives PDC drill bit
Motive force further improves efficiency of breaking rock to improve the drilling speed of PDC drill bit.Platform is installed on the rack A10
17, the motor 9 is fixedly installed on platform 17.
The course of work of the invention is as follows:
Before work, the internal screw thread of the conically-tapered threaded head of 1 upper end of bit body and drilling rod is connected, to install entire PDC drill bit；Work
When making, lowering drill pipes simultaneously make its high-speed rotation, drilling rod drive PDC drill bit high-speed rotation, in PDC drill bit wedging stratum, are creeping into
In the process, worker operates high-pressure pump on the ground, and high-pressure fluid, partial high pressure stream are pumped into fluid chamber 2 by high-pressure pump
Body successively through water outlet 6, pipe fitting A13, hose 16, pipe fitting B15, finally projected from jet pipe 12.
As shown in figure 4, being enclosed with dope in PDC cutting tooth 5 when PDC drill bit is when creeping into soft formation, PLC is controlled at this time
Device processed is passed through electric current into cable 18, and motor 9 drives shaft 14 around swing, further that jet pipe 12 is driven to rotate certain angle
Degree, in 12 rotation process of jet pipe, PDC cutting tooth 5 that the high-pressure fluid ejected from jet pipe 12 is inswept will be wrapped in PDC and cut
The dope cut on tooth 5 washes away, and ensures that the normal work of PDC drill bit, improves the efficiency of broken rock.
As shown in figure 5, broken clast bulk deposition passes through at this time in shaft bottom when PDC drill bit is when creeping into hard formation
PLC controller is passed through electric current into cable 18, stops galvanization immediately when jet pipe 12 is turned to perpendicular to shaft bottom, from jet pipe 12
The clast at the direct flushing manhole bottom of the high-pressure fluid ejected, so that drilling well clast is cleaned out quickly, and clast is along hoistway
Discharge, accelerates the discharge of clast, so that effectively preventing clast is largely deposited on shaft bottom, improves efficiency of breaking rock.
In addition, either creeping into still in soft formation drilling in hard formation, another part high-pressure fluid is also from apopore 7
In eject, due to the water discharging direction of apopore 7 and the cutting direction of PDC cutting tooth 5 on the contrary, foring torque, that is, project
Fluid gives the certain motive force of PDC drill bit and further improves efficiency of breaking rock to improve the drilling speed of PDC drill bit.
