Description
Technical field
The utility model relates to a kind of oil drilling drill bit, and what be specifically related to is a kind of six wing detachable oil drilling drill bits.
Background technology
Oil bit is the important tool of oil drilling, and the quality of its service behaviour will directly affect drilling quality, drilling efficiency and drilling cost.
Maximum still rock bit is applied in oil drilling and geological drilling.Rock bit has impact when rotated, crushes and the effect of shearing-crushing formation rock, so, rock bit can adapt to soft, in, hard various stratum.Particularly after jet nozzled rock bit and long nozzle rock bit occur, the bit speed of rock bit improves greatly, is the once great revolution in rock bit development history.Rock bit can be divided into mill teeth (steel-tooth) rock bit, inserted (on gear wheel insert hard-metal insert) rock bit by tooth type; Single cone, two gear wheel, three gear wheels and drilling bit of multiple rollers can be divided into by gear wheel number.At present, use at most both at home and abroad, the most generally tricone bit.
Oil, and various probing industry in rock bit be indispensable pith, but rock bit concerning some probing industries price so high, and because of gear wheel be the structure that is welded as a whole with gum, if one of them gear wheel damages, then need all to change whole drill bit, cost is high.
Utility model content
The purpose of this utility model is to solve the problem that rock bit cost is high, application life is relatively short traditional in prior art, provides that long service life, equipment investment cost are low, the one six wing detachable oil drilling drill bit of easy maintenance.
For solving above-mentioned shortcoming, the technical solution of the utility model is as follows:
A kind of six wing detachable oil drilling drill bits, comprise drill body, be arranged on three operator wings on drill body pileum and three secondary wings, and the shower nozzle composition between the operator wing and secondary wing, described drill body is provided with three for installing the operator wing mounting groove of the operator wing, and three for installing the secondary wing mounting groove of secondary wing, the degree of depth of this operator wing mounting groove and secondary wing mounting groove is all greater than 1cm; And the distance after installing between the operator wing and operator wing mounting groove and after installing between secondary wing and secondary wing mounting groove is all less than 1mm.
By the setting of operate wing mounting groove and secondary wing mounting groove, effective dismounting and installation realizing the operator wing and secondary wing, thus can only changing the operator wing or secondary wing when an operator wing or secondary wing damage wherein, without the need to changing whole drill bit, and then reducing equipment investment cost.
Meanwhile, because the degree of depth of operator wing mounting groove and secondary wing mounting groove is all greater than 1cm, and the distance after installing between the operator wing and operator wing mounting groove and after installing between secondary wing and secondary wing mounting groove is all less than 1mm; By this setting, the stability that effective raising operator wing and secondary wing are installed, the ability to bear of effective raising operator wing and secondary wing, effectively increases application life of the present utility model simultaneously.
As optimally set-up mode, described operator wing mounting groove and secondary wing mounting groove are disposed on drill body.
In order to reach the object of stable boring better, the described operator wing exceeds 5 ~ 7mm than secondary wing.
In order to can effectively together be discharged with drilling fluid by the silt etc. after fragmentation, the described operator wing extends drill body 5 ~ 7mm.By 5 ~ 7mm of extending of the operator wing, effectively make to form space between adjacent two operator wings, and then the discharge such as the silt rubble conveniently got out.
In order to reach in drilling technology circulating effect best, described shower nozzle is positioned at the middle position of drill body pileum.
The utility model compared with prior art, has the following advantages and beneficial effect:
1, the utility model is by the setting of operate wing mounting groove and secondary wing mounting groove, effective dismounting and installation realizing the operator wing and secondary wing, thus the operator wing or secondary wing can only be changed when an operator wing or secondary wing damage wherein, without the need to changing whole drill bit, and then reduce equipment investment cost;
2, setting of the present utility model effectively can improve the stability that the operator wing and secondary wing are installed, and improves the ability to bear of the operator wing and secondary wing simultaneously effectively, effectively increases application life of the present utility model;
3, in the utility model by 5 ~ 7mm of extending of the operator wing, effectively make to form space between adjacent two operator wings, and then the discharge such as the silt rubble conveniently got out; Meanwhile, by being positioned at the shower nozzle acting in conjunction of drill body pileum middle position, effectively to reach in drilling technology circulating effect best.
