Abstract

The utility model relates to an underground surveying technology field, concretely relates to petroleum geology is drill bit for exploration drilling, it includes cylinder cutting piece, location axle, mount, the location position of axle is central in cylinder cutting piece, location axle end -to -end connection is on the mount, the mount is located cylinder cutting piece bottom, the utility model discloses petroleum geology is drill bit for exploration drilling, its simple structure, convenient to use, its adopts location axle design, can effectually prevent that the drill bit from removing, improves cutting stability and life, it adopts intensive cylinder cutting piece, can effectually smash the cutting plane, and it is effectual has avoided traditional drill bit to be blocked the damage by hard rock, great improvement work efficiency and life, reduced manufacturing cost.

Description

Petroleum geology exploration drilling well drill bit

Technical field

This utility model relates to subterranean survey technical field, is specifically related to petroleum geology exploration drilling well drill bit.

Background technology

Prospecting bore bit plays the biggest effect at petroleum exploration field, so the quality of drill bit is particularly important, Currently used prospecting bore bit structure is sufficiently complex, and production cost is high, and often by hard rock card Live, cause bit damage, reduce work efficiency, increase production cost.

Utility model content

The purpose of this utility model is the defect for prior art and deficiency, it is provided that a kind of simple in construction, Petroleum geology exploration drilling well drill bit reasonable in design, easy to use, it include cylinder cutting sheet, locating shaft, Fixed mount；Locating shaft is positioned at cylinder cutting sheet center；Locating shaft end is connected on fixed mount；Fixed mount position Bottom cylinder cutting sheet.

After using said structure, this utility model has the beneficial effect that petroleum geology described in the utility model is surveyed Prospecting bit well drill bit, its simple in construction, easy to use, it uses locating shaft design, can effectively prevent from boring Head is mobile, improves cutting stability and service life；It uses intensive cylinder cutting sheet, can effectively by Facet is pulverized, and it effectively avoids conventional drill and blocked damage by hard rock, is greatly improved Work efficiency and service life, reduce production cost.

Accompanying drawing explanation

Accompanying drawing described herein is used to offer and is further appreciated by of the present utility model, constitutes the application's A part, but it is not intended that improper restriction of the present utility model, in the accompanying drawings:

Fig. 1 is this utility model structural representation；

Description of reference numerals:

1-cylinder cutting sheet, 2-locating shaft, 3-fixed mount, 1-1 groove.

Detailed description of the invention

This utility model, schematic reality therein is described in detail below in conjunction with accompanying drawing and specific embodiment Execute example and illustrate only for explaining this utility model, but being not intended as restriction of the present utility model.

As it is shown in figure 1, the petroleum geology exploration drilling well drill bit described in this detailed description of the invention, it includes circle Post cutting sheet 1, locating shaft 2, fixed mount 3；Locating shaft 2 is positioned at cylinder cutting sheet 1 center；Locating shaft 2 End is connected on fixed mount 3；Fixed mount 3 is positioned at bottom cylinder cutting sheet 1.

Further: described cylinder cutting sheet 1 includes that groove 1-1, groove 1-1 are positioned at cylinder cutting sheet 1 Top.

Locating shaft 2 front end is taper, relies on being fixed on facet of pressure stability on its top；Drill bit leads to Crossing outside machinery drives fixed mount 3 to rotate；Fixed mount 3 drives the cylinder being fixed thereon cutting sheet 1 to revolve Turn；Owing to the space between cylinder cutting sheet 1 is little, it can circumgyration incision rock, on one side general cuts Face smash, thus stable carry out underground easily and deeply drill.

Petroleum geology exploration drilling well drill bit described in the utility model, its simple in construction, easy to use, it Employing locating shaft designs, and can effectively prevent drill bit from moving, and improves cutting stability and service life；It is adopted With intensive cylinder cutting sheet, can effectively be pulverized by facet, it is hard that it effectively avoids conventional drill Hard rock blocks damage, is greatly improved work efficiency and service life, reduces production cost.

The above is only better embodiment of the present utility model, therefore all according to this utility model patent application model Enclose equivalence change or modification that described structure, feature and principle is done, be all included in this utility model patent In application range.
