Abstract
The utility model provides a pregnant body diamond bit that inlays of column, wing are 5, including 3 operator wings. The conical point is equipped with 1 PDC tooth including the operator wing. Wing cutting edge department is equipped with 1 row of radial pregnant body of inlaying, and arrangement rule's the pregnant body of inlaying of axial is laid on the wing surface at cutting edge rear. Be equipped with 5 water holes between the wing, PDC tooth department is equipped with 2 water holes. Protecting footpath piece side cut department and being equipped with 1 row of PDC tooth, arrangement rule's guarantor footpath piece tooth is laid to the guarantor footpath piece at side cut rear. The utility model discloses a pregnant body of inlaying cylindric or the bulb form replaces whole pregnant the inlaying of drill bit, is favorable to improving the production efficiency of single crystal diamond, simultaneously, the water hole of pyramis setting between the wing and in the drill bit can provide good cooling effect for the pregnant body of inlaying to reduce the loss of single crystal diamond performance, further, according to drill bit operating characteristic, use PDC tooth is as the interior pyramis of drill bit and protect the cutting component that the footpath piece was located, is favorable to creeping into under the prerequisite of requirement in the assurance, reduces drill bit manufacturing cost.
Description
Technical field
This utility model relates to petroleum drilling well drilling tool technical field, especially a kind of column impregnated body diamond drill bit.
Background technology
Diamond has higher hardness and wearability, it is adaptable to make the cutting structure of oil drilling tools.Wherein, the mechanical performance of single-crystal diamond is the most excellent, improves its work efficiency, is conducive to promoting drill bit drilling speed and drilling depth ability.
Existing diamond-impregnated bit is evenly distributed in bit matrix sintering single-crystal diamond exactly and forms.But in sintering process, high temperature has certain destruction to the performance of diamond.During simultaneously as drill bit creeps into, single crystal diamond layer almost covers full shaft bottom, and the cooling effect of drilling fluid is poor, in the case of high-speed turbine drilling well, and easy premature harm single crystal diamond layer performance.
Utility model content
This utility model provides a kind of column impregnated body diamond drill bit, to solve the problems referred to above.Laid at the uniform of bit wing wing surface by cylindric or bulb shape impregnated body, replace drill bit entirety impregnated, be conducive to improving the production efficiency of single-crystal diamond；Meanwhile, the water hole that between wing and in drill bit, tapering is arranged, it is possible to provide good cooling effect for impregnated body, thus reduce the loss of single-crystal diamond performance；Further, according to bit operation characteristic, use PDC tooth as the cutting element at tapering in drill bit and gauge block, be conducive to, on the premise of ensureing to creep into requirement, reducing drill produced cost.
In order to realize the purpose of this utility model, plan employing techniques below:
A kind of column impregnated body diamond drill bit, including wing and gauge block, it is characterized in that, described wing is 5, and including 3 operator wings, the described operator wing is provided with 1 PDC tooth at interior conical point, 1 row radially impregnated body it is provided with at described wing blade, the described blade surface at blade rear is laid with the axial impregnated body of queueing discipline, is provided with 5 water holes, is provided with 2 described water holes at described PDC tooth between described wing；Being provided with PDC tooth described in 1 row at described gauge block trimming, the described gauge block at trimming rear is laid with the gauge block tooth of queueing discipline.
Further, the impregnated body of described radial direction is cylindric.
Further, described axial impregnated body is cylindric or bulb shape.
The beneficial effects of the utility model are:
1. laid at the uniform of bit wing wing surface by cylindric or bulb shape impregnated body, replace drill bit entirety impregnated, be conducive to improving the production efficiency of single-crystal diamond, thus improve drill bit drilling speed and drilling depth ability.
2. the water hole that between wing and in drill bit, tapering is arranged, it is possible to provide good cooling effect for impregnated body, thus reduce the loss of single-crystal diamond performance.
3. use PDC tooth as the cutting element at tapering in drill bit and gauge block, be conducive to, on the premise of ensureing to creep into requirement, reducing drill produced cost.
Accompanying drawing explanation
Fig. 1 shows structural representation of the present utility model.
Fig. 2 shows crown top view of the present utility model.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of column impregnated body diamond drill bit, including wing 1 and gauge block 2.
Described wing 1 is 5, including 3 operator wings 11.Asymmetric 5 wing structures are conducive to optimizing bottom-hole flow field, it is simple to Cutting movement.
The 1 row impregnated body of cylindric radial direction 4 it is provided with at described wing 1 blade.Be conducive to improving stock-removing efficiency.
Described wing 1 surface at blade rear is laid with the cylindric of queueing discipline or the axial impregnated body 5 of bulb shape.For more traditional overall impregnated bit, be conducive to avoiding single-crystal diamond concentrated wear, thus improve the production efficiency of single-crystal diamond.
It is provided with 5 water holes 6 between described wing 1, at described PDC tooth 3, is provided with 2 described water holes 6.Described water hole 6 is uniformly distributed in inner cone and the position easy to wear such as nose, shoulder of drill bit, beneficially provides good cooling effect for impregnated body, thus reduces the loss of single-crystal diamond performance.
The described operator wing 11 is provided with 1 PDC tooth 3 at interior conical point.Being provided with PDC tooth 3 described in 1 row at the trimming of described gauge block 2, the described gauge block 2 at trimming rear is laid with the gauge block tooth 7 of queueing discipline.Use described PDC tooth 3 as the cutting element at tapering in drill bit and described gauge block 2, be conducive to, on the premise of ensureing to creep into requirement, reducing drill produced cost.
In drill bit drilling process, described water hole 6, for being arranged at described PDC tooth at inner cone 3 and being arranged at the impregnated body of described radial direction 4 at described wing 1 and described axial impregnated body 5 provides drilling fluid, cools down.Described wing 1 and the impregnated body of described radial direction 4 complete main cutwork, to protect described axial impregnated body 5 to avoid quick-wearing；Described axial impregnated body 5 carries out assisted machining, thus improves the production efficiency of single-crystal diamond in drill bit.
