Abstract
The utility model discloses one kind from protection type expanding wall prospecting bore bit, including upper end with the bit body that connector and lower end are cutting edge, it is arranged at articulated section circumferentially uniform on the upside of bit body, the auxiliary connecting rod being connected on each articulated section, it is arranged at the auxiliary drill bit of auxiliary connecting rod end, and the elastic shrinkage part between auxiliary connecting rod and bit body is connected to, wherein, the angle between the auxiliary connecting rod and bit body is between 100 ° and 150 °.The utility model is mainly drilled by bit body to subterranean strata, expanding wall is carried out to borehole wall using the auxiliary drill bit at rear portion during bit body continues probing, and when rock stratum is really up to the mark cause auxiliary drill bit can not normally drill when, the borehole wall can make auxiliary drill head be bounced back under the effect of elastic shrinkage part to pressure caused by auxiliary drill bit, self-protection is carried out, the service life of drill bit is improved on the basis of effective expanding wall.
Description
Technical field
A kind of prospecting bore bit is the utility model is related to, is to be related to one kind from protection type expanding wall prospecting bore bit specifically.
Background technology
Prospecting bore bit is the important tool of oil exploration drilling, be when exploring for oil for drilling through rock stratum oil, its
The quality of service behaviour will directly affect exploration quality, exploration efficiency and exploration cost.
In exploration process, drill bit is in contact with rock, so as to act on fractured rock by cutting, punching press etc..With brill
The development of spy technology, drill bit structure are also constantly upgrading, and as rock bit, diamond drill machine are first-class, are needed for different geological stratifications
Drilled using different drill bits, therefore the purposes of many drill bits is more single.Existing currently used diamond bit is main
It is that exploration drilling is carried out to solid rock using the high rigidity of diamond, but with the increase of bit depth, the well of upper end
Wall can not effectively extend, it is easy to influence the entrance and normal operation of follow-up mechanism, therefore also need to special expanding wall and bore
Head, thus caused whole drilling process complexity is cumbersome, and exploration efficiency is relatively low.
Utility model content
For above-mentioned the deficiencies in the prior art, the utility model offer one kind is simple in construction, ingenious in design, drilling resultses are good
From protection type expanding wall prospecting bore bit.
To achieve these goals, the technical solution adopted in the utility model is as follows：
It is a kind of to be set from protection type expanding wall prospecting bore bit, including upper end with the bit body that connector and lower end are cutting edge
Articulated section circumferentially uniform, the auxiliary connecting rod being connected on each articulated section on the upside of bit body, it is arranged at auxiliary and connects
The auxiliary drill bit of boom end, and the elastic shrinkage part being connected between auxiliary connecting rod and bit body, wherein, the auxiliary connecting rod
Angle between bit body is between 100 ° and 150 °.
Specifically, the elastic shrinkage part is made up of compression spring inner core and soft protection overcoat.
Compared with prior art, the utility model has the advantages that：
The utility model is mainly drilled by bit body to subterranean strata, the profit during bit body continues probing
Carry out expanding wall to borehole wall with the auxiliary drill bit at rear portion, and when rock stratum is really up to the mark cause auxiliary drill bit normally to drill when, the borehole wall
Auxiliary drill head can be made to be bounced back under the effect of elastic shrinkage part to pressure caused by auxiliary drill bit, self-protection is carried out, effective
The service life of drill bit is improved on the basis of expanding wall, and the utility model is novel, it is ingenious in design, it is simple in construction, it is easy to
Realize, be with a wide range of applications, be adapted to popularization and application.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples, and embodiment of the present utility model includes
But it is not limited to the following example.
Embodiment
As shown in figure 1, it is a kind of from protection type expanding wall prospecting bore bit, including upper end is cutting edge 3 with connector 2 and lower end
Bit body 1, it is arranged at articulated section 4 circumferentially uniform on the upside of bit body, the auxiliary connecting rod being connected on each articulated section
5, the auxiliary drill bit 6 of auxiliary connecting rod end is arranged at, and the elastic shrinkage part 7 being connected between auxiliary connecting rod and bit body,
Wherein, the angle between the auxiliary connecting rod and bit body is between 100 ° and 150 °.Specifically, the elastic shrinkage part by
Compression spring inner core and soft protection overcoat composition.
Above-described embodiment is only preferred embodiment of the present utility model, not to the limitation of scope of protection of the utility model,
In every case design principle of the present utility model, and the change for carrying out non-creativeness work on this basis and making are used, all should
Belong within the scope of protection of the utility model.
