Abstract

A kind of oriented diamond drill bit, comprise drill body, it is characterized in that the bizet of described drill body is provided with the first, second, third, fourth, the 5th wing of radial also circular array, each wing end face is equipped with brill toothholder, wherein the first, the 3 two relative wing is near the center of circle, on these two relative wings, bore the equal concentric circles of toothholder near first, second, third of one end, the drill body center of circle and arrange.The utility model has the features such as structure is simple, positioning stablity, anti-stop ring mill.Beneficial effect in the utility model: two concentric circles gaps Tooth arrangement design, the rock in drilling process in concentric circles cloth backlash can not be cut, and effectively utilizes rock stratum jut to assign to reach locking track, the object in stabilizing tool face.Locking projected path, can carry out according to planned course in directed drilling process, and in whole directional drilling process, tool-face is steady, and fixed not de-pressure, do not run orientation, avoid slipping drilling, directed rate of penetration is much improved.

Description

A kind of oriented diamond drill bit
Technical field
The utility model belongs to oil drilling tools field, particularly relates to a kind of oriented diamond drill bit.
Background technology
Diamond is commonly called as " spark ".The namely former body of our the normal diamond said, it is a kind of mineral be made up of carbon, is the allotrope of carbon.Diamond is occurring in nature the hardest naturally occurring material.Widely, be wherein used as oil drilling widely, be the main material of drill bit to adamantine purposes.
Diamond bit belongs to one-piece drill bit, and whole drill bit does not have movable component, and relatively simple for structure, having high strength, high abrasion and shock proof ability, is one of large new technology of world well three eighties in 20th century.As shown in Figure 4, existing general diamond bit mostly number is not suitable for directional drilling, and existing oriented diamond drill bit, exists tool-face instability in directed drilling, tool-face controls difficulty, de-pressure, drill bit can not effective wedging stratum, causes the problems such as slipping drilling, can not carry out according to planned course well, affect directed velocity, add the directed drilling time, drilling cost is increased.
Summary of the invention
The utility model provides the oriented diamond drill bit that a kind of structure is simple, reliability is high, can locate, with solve existing cost high, easy to wear, be not suitable with the technical problems such as directed drilling.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of oriented diamond drill bit, comprise drill body, it is characterized in that the bizet of described drill body is provided with the first, second, third, fourth, the 5th wing of radial also circular array, each wing end face is equipped with brill toothholder, wherein the first, the 3 two relative wing is near the center of circle, on these two relative wings, bores the equal concentric circles of toothholder arrange near first, second, third of one end, the drill body center of circle.
As preferably, in described first, second, third, fourth, the 5th wing, except on the first, the 3rd wing three to except concentric round bur toothholder, other all brill toothholder non-concentric is arranged.
As preferably, described brill toothholder is provided with diamond compact.
As preferably, the end of described wing is connected with gauge body, and gauge side portion is provided with diamond compact.
As preferably, the drill body between described wing is also arranged hole, multiple water route.
The utility model has the features such as structure is simple, positioning stablity.Its three concentric circles gap Tooth arrangement design, the rock in drilling process in concentric circles cloth backlash can not be cut, and effectively utilizes rock stratum jut to assign to reach locking track, the object in stabilizing tool face.
Tool-face is stable also can arbitrarily be controlled, and locking projected path, can carry out according to planned course in directed drilling process, and in whole directional drilling process, the stable de-pressure of tool-face, do not run orientation, avoid slipping drilling, directed rate of penetration is much improved.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is upward view of the present utility model;
Fig. 3 is running schematic diagram of the present utility model;
Fig. 4 is the running figure of existing drill bit;
Fig. 5 is the enlarged drawing at A place in Fig. 1;
Fig. 6 is that schematic diagram cuts open in the office of the utility model drilling well.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in further detail.
Composition graphs 1, 2, 3, shown in 5, this oriented diamond drill bit is by drill body 9, brill toothholder 6 on wing 10 and wing 10 end face, the bizet of drill body 9 is provided with radial and display ringwise first, second, 3rd, 4th, 5th wing 1, 2, 3, 4, 5, each wing end face is equipped with and bores toothholder 6, wherein first, 3 two relative wing 1, 3 near the center of circle, on these two relative wings, near first of one end, the drill body center of circle, second, 3rd bores toothholder 6 all concentric circles settings, first, second, 3rd, 4th, 5th wing 1, 2, 3, 4, in 5, except first, 3rd wing 1, on 3, three to outside concentric round bur toothholder 6, other all brill toothholder 6 non-concentric is arranged.Rock in drilling process in concentric circles cloth backlash can not be cut, and effectively utilizes rock stratum jut to assign to reach locking track, stabilizing tool face; Face stabilizer in drill bit creeps into, not de-pressure, does not run orientation, avoids slipping drilling, can improve directional drilling speed, reduce directed drilling cost.
The end of wing is connected with gauge body 12, and gauge body 12 sidepiece is provided with diamond compact 31, and gauge body 12 protects drill body 9, and the diamond compact 31 on gauge body 12 cuts drill body rock all round, ensures that drill body 9 creeps into.Drill body between wing is also arranged hole, multiple water route 8, hydrodynamic lubrication drill bit in hole, water route 8, liquid rinse is pasted onto the particle on drill bit, improves rate of penetration.
Shown in composition graphs 6, the utility model in drilling well with earth hookup, bore toothholder 6 drilling well in earth 10, boring soldering on toothholder 6 has diamond compact 31 rock cutting, reduces directional drilling resistance, creeping into of protection drill body 9.
Finally it should be pointed out that above detailed description of the invention is only the more representational example of the utility model.Obviously, the utility model is not limited to above-mentioned detailed description of the invention, can also have many distortion.Every above detailed description of the invention is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all should think and belong to protection domain of the present utility model.
