Abstract
The utility model discloses a kind of quick diamond compact bits, it is characterized by comprising bit bodys and drilling rod, it is threaded connection between the bit body and drilling rod, the bit body is two layers of stepped construction, including upper level drill bit and lower level drill bit, the radius of the upper level drill bit is less than the radius of lower level drill bit, and annular is equipped with multiple tooth sockets on the bit body, cutting members are equipped at the top of the upper level drill bit, the cutting members are equipped with diamond compact.This practical Double-ladder formula structure for having the advantages that bit body and tooth socket design can increase drill bit wedging ability and cutting power, and whole penetration rate can be improved in the diamond compact in the cutting members at top, and more convenient pierce.
Description
Technical field
The utility model relates to bit technique field, in particular to a kind of quick diamond compact bits.
Background technique
Diamond compact is the composite material for having diamond layer and hard alloy substrate to synthesize under high-temperature and high-pressure conditions,
Have the characteristics that hardness is high, wearability is good, is now widely used on the drill bits such as oil and gas well drilling, geological prospecting.Tradition
Diamond compact be cylindrical shape, the radius circulars such as the radial section of cutting face and matrix is have the following deficiencies:
It will appear the problem of wedging stratum is difficult, rate of penetration reduces when drilling is compared with hard formation；When creeping into broken ground, composite sheet
Wedging will receive composite sheet side protrusion limitation, reduce the wedging of drill bit, limit the rate of penetration of drill bit；With Buddha's warrior attendant
Rock layers abrasion, causes the contact area on diamond layer and stratum to be gradually increased, and drill bit wedging depth of stratum is reduced, power auger prompt drop
It is low.
Utility model content
The technical problems to be solved in the utility model is to overcome the above technical problem, provides a kind of quick diamond compact
Drill bit.
In order to solve the above technical problems, technical solution provided by the utility model is a kind of quick diamond compact drilling
Head, it is characterised in that: including bit body and drilling rod, to be threadedly coupled between the bit body and drilling rod, the bit body is two
The radius of layer stepped construction, including upper level drill bit and lower level drill bit, the upper level drill bit is less than lower level drill bit
Radius, annular is equipped with multiple tooth sockets on the bit body, and cutting members are equipped at the top of the upper level drill bit, are set in the cutting members
There is diamond compact.
Preferably, the cutting members number is four, sets that there are two round diamond compacts in each cutting members.
Preferably, the radius of the lower level drill bit is greater than the outer diameter of drilling rod.
Preferably, the bit body and drilling rod are internal rounded hollow structure.
The utility model has the advantages that the Double-ladder formula structure of bit body and tooth socket design compared with prior art
Drill bit wedging ability and cutting power can be increased, whole brill can be improved in the diamond compact in the cutting members at top
Enter speed, more convenient pierce.
Detailed description of the invention
Fig. 1 is a kind of quick diamond compact bit structural schematic diagram of the utility model.
Fig. 2 is a kind of quick diamond compact bit top structure schematic diagram of the utility model.
It is as shown in the figure: 1, bit body, 2, drilling rod, 3, upper level drill bit, 4, lower level drill bit, 5, tooth socket, 6, cutting members, 7,
Diamond compact.
Specific embodiment
The following describes the utility model in further detail with reference to the accompanying drawings.
In conjunction with attached drawing, a kind of quick diamond compact bit, it is characterised in that: described including bit body 1 and drilling rod 2
To be threadedly coupled between bit body 1 and drilling rod 2, the bit body 1 is two layers of stepped construction, including upper level drill bit 3 is under
Level drill bit 4, the radius of the upper level drill bit 3 are less than the radius of lower level drill bit 4, and annular is equipped with more on the bit body 1
A tooth socket 5, cutting members 6 are equipped at the top of the upper level drill bit 3, and the cutting members 6 are equipped with diamond compact 7.
6 numbers of the cutting members are four, set that there are two round diamond compacts 7 in each cutting members 6.
The radius of the lower level drill bit 4 is greater than the outer diameter of drilling rod 2.
The bit body 1 and drilling rod 2 are internal rounded hollow structure.
The tooth socket design of the utility model bit body can increase drill bit wedging ability, Double-ladder formula structure, upper layer
Radius be less than lower layer radius, cutting power, the diamond compact in the cutting members at top, due to diamond can be improved
Composite sheet is very hard, it is possible to improve whole penetration rate, tooth socket is also used as lubricant, drilling rubble or broken
The access of bits realizes the effect of a structure multiple use, and more convenient pierce, and indirectly improves and pierces speed
Degree.
The utility model and embodiments thereof are described above, this description is no restricted, shown in attached drawing
Be also one of the embodiments of the present invention, actual structure is not limited to this.All in all if this field
Those of ordinary skill is enlightened by it, without deviating from the purpose of the present invention, not inventively design with
The similar frame mode of the technical solution and embodiment, all should belong to the protection range of the utility model.
