Description
Technical field
The utility model relates to drill bit design technical field, relates in particular to a kind of petroleum geology exploration drill bit.
Background technology
At present, along with the development of oil exploration technology, drill bit also, constantly upgrading, has rock bit at present, and diamond compact bit etc. are of a great variety, in order to adapt to the needs of different soil layer oil drillings, adopt different.Drill bit oil exploration rig is the critical machine of oil exploration and the probing of geology mining site, and drill bit is wherein broken formation, forms the instrument of well head, and its parameters quality is directly connected to the height of rig efficiency and the overall performance of rig.For the general use of oil mine prospection be scraper type drill bit, it mainly relies on shearing broken rock.Yet, on existing drill bit, lack the device of the location that contributes to joint, this be unfavorable for reducing groove location with wearing and tearing cause the inaccurate problem of joint location, on the drill bit also having, lack and contribute to the location of fixed mount and the device of installation, can not meet real Production requirement.
Utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of petroleum geology exploration drill bit is provided.
The utility model is to be achieved through the following technical solutions:
A kind of petroleum geology exploration drill bit, comprise joint, the upper end of described joint is provided with rectangle projection and arc bump, described arc bump is positioned at the lower end of rectangle projection, the lower end of joint is connected with bit body, and the middle part of described bit body is provided with one-level locating piece, and described one-level locating piece is provided with secondary locating piece, the lower end of bit body is provided with gore, and the downside of described triangular bump is provided with alloy column.
As optimal technical scheme of the present utility model, in described bit body, be provided with passage, the bottom of bit body is also provided with medicine outlet, and bit body bottom is also provided with groove, and described groove is provided with projecting shaft, and the lower end of described projecting shaft is provided with positioning head.
As optimal technical scheme of the present utility model, described gore has two at least, and is symmetrically distributed in the lower end of bit body.
Compared with prior art, the beneficial effects of the utility model are: the utility model contributes to the location of joint by rectangle projection and arc bump are set, this contribute to reduce groove location with wearing and tearing cause the inaccurate problem of joint location, by being provided with the bit body of the first locating piece of the second locating piece, contribute to location and the installation of fixed mount, this effectively solves in the fixing unsettled problem of rig, and simple in structure, easy to operate, economical and practical.
