Description

A kind of oil drilling rock bit based on S shape operator head
Technical field
The utility model relates to a kind of oil drilling rock bit, and what be specifically related to is a kind of oil drilling rock bit based on S shape operator head.
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 a kind of oil drilling rock bit based on S shape operator head of increase the service life, reduce cost of labor, easy maintenance.
For solving above-mentioned shortcoming, the technical solution of the utility model is as follows:
A kind of oil drilling rock bit based on S shape operator head, comprise drill body, the bizet of this drill body is provided with serpentine operator head, and be provided with more than one shower nozzle in the arc cell body of this serpentine operator head, the shower nozzle in arc cell body is arrangement in " C " font.
Coordinated with the shower nozzle that " C " font arranges by serpentine operator head, while effectively reducing bearing pair relative linear velocity, reduce rubbing surface temperature rise, effectively can improve the bearing life under high the pressure of the drill or high rotating speed drilling technology condition and bearing reliability.
Further, conveniently install replacing, simultaneously effective Loss reducing cost, the bizet of described drill body is provided with the mounting groove matched with head shapes of operating, and this operator head is arranged in this mounting groove.
As the set-up mode of optimum, the two ends of described operator head are provided with fixing hole, and drill body is then provided with bolt hole with fixing hole corresponding position, and this operator head is bolted on drill body.
By above-mentioned setting, not only can effectively reach the effect removed and installed, and can not impact high the pressure of the drill or high rotating speed drilling technology when using, effect is very remarkable.
In order to improve drilling efficiency, described operator head both sides are also provided with secondary cutter head.
Conveniently safeguard installation, be convenient to change, cost-saving, described secondary cutter head is two simultaneously simultaneously, is detachably arranged on operator head both sides respectively.
The utility model compared with prior art, has the following advantages and beneficial effect:
1, the utility model is coordinated with the shower nozzle that " C " font arranges by serpentine operator head, while effectively reducing bearing pair relative linear velocity, reduce rubbing surface temperature rise, effectively can improve the bearing life under high the pressure of the drill or high rotating speed drilling technology condition and bearing reliability;
2, operate in the utility model head and secondary cutter head is all removably connected on drill body, and effectively convenient replacing when damaging, avoids the waste of other cutter heads and drill body, and then reduce the input cost of drill bit in drilling technology;
3, in the utility model, drilling fluid can spray from shower nozzle by the shower nozzle of " C " font arrangement better, serpentine operator head is made to reach the effect of Homogeneous cooling best, and then effectively improving the application life of serpentine operator head, the equipment cost reducing drilling technology drops into.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is detonation configuration schematic diagram of the present utility model.
Wherein, corresponding in accompanying drawing Reference numeral is as follows:
1-drill body, 2-operates head, 3-shower nozzle, 4-mounting groove, 5-fixing hole, 6-bolt hole, the secondary cutter head of 7-.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing thereof, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment 1
A kind of oil drilling rock bit based on S shape operator head, comprise drill body 1, the bizet of this drill body 1 is provided with serpentine operator 2, is provided with more than one shower nozzle 3, the arrangement in " C " font of the shower nozzle 3 in arc cell body in the arc cell body of this serpentine operator 2.
As shown in Figure 1, in the present embodiment, operator 2 is in serpentine, be fixed on the bizet of drill body 1, the other end that drill body 1 bizet is relative is communicated with drilling fluid conduit, drilling fluid in drilling fluid conduit flows into from the other end that drill body 1 bizet is relative, then spray from the shower nozzle 3 of drill body 1 bizet, flow in the hoistway bored, and then make drilling fluid reach its due effect.
And combined by " C " font and serpentine, effectively make the operator of drill body 1 bizet 2 obtain the effect of Homogeneous cooling best, thus effectively can improve the application life of operator 2, reduce the loss of equipment in drilling process, cost-saving.
Embodiment 2
The difference of the present embodiment and embodiment 1 is, in the present embodiment, this serpentine operator 2 is removably connected to the bizet of drill body 1, and concrete set-up mode is as follows:
The bizet of described drill body 1 is provided with and a mounting groove for 2 mating shapes 4 of operating, and this operator 2 to be arranged in this mounting groove 4.The two ends of described operator 2 are provided with fixing hole 5, and drill body 1 is then provided with bolt hole 6 with fixing hole 5 corresponding position, and this operator 2 is bolted on drill body 1, as depicted in figs. 1 and 2.
