Abstract
The utility model discloses a kind of durable drilling well nozzle, comprise nozzle body, screw thread is provided with outside nozzle body, nozzle body is arranged on drill bit by screw thread, the intrinsic conduit wall of nozzle offers many guiding gutters, the cross section of guiding gutter is U-shaped, and stays in the shape of a spiral on the intrinsic conduit wall of nozzle; Described nozzle body is shaping by carborundum one-step casting, and this external covering double layer of metal film of nozzle, wherein internal layer is copper film, and skin is nickel film; This nozzle hardness is high, extends the application life of nozzle, not only avoids the worry that workman frequently changes nozzle, adds drilling efficiency, and reduce cost.
Description
Technical field
The utility model relates to a kind of nozzle, specifically a kind of durable drilling well nozzle.
Background technology
In oil exploitation process, drill bit is important parts.Drilling well drill bit is all provided with multiple nozzle, cleans Cutter by nozzle and reduce mud drum, improving the rotating speed of drill bit.Most nozzle is steel part in the market, and application life is short, and needing frequently is bit change-over nozzle, not only affects drilling efficiency, and adds cost.
Utility model content
The purpose of this utility model is to provide a kind of durable drilling well nozzle, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A durable drilling well nozzle, comprises nozzle body, is provided with screw thread outside nozzle body, nozzle body is arranged on drill bit by screw thread, the intrinsic conduit wall of nozzle offers many guiding gutters, and the cross section of guiding gutter is U-shaped, and stays in the shape of a spiral on the intrinsic conduit wall of nozzle; Described nozzle body is shaping by carborundum one-step casting, and this external covering double layer of metal film of nozzle, wherein internal layer is copper film, and skin is nickel film.
As further program of the utility model: the quantity of described guiding gutter is 4, and uniform intervals is distributed in nozzle body.
Compared with prior art, the beneficial effects of the utility model are: this nozzle is shaping by carborundum one-step casting, this external covering double layer of metal film of nozzle, wherein internal layer is copper film, and skin is nickel film, considerably increases the hardness of nozzle, extend the application life of nozzle, not only avoid the worry that workman frequently changes nozzle, add drilling efficiency, and reduce cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of durable drilling well nozzle.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the sectional view of durable drilling well nozzle.
In figure: 1-nozzle body, 2-screw thread, 3-guiding gutter.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 3, in the utility model embodiment, a kind of durable drilling well nozzle, comprises nozzle body 1; Be provided with screw thread 2 outside described nozzle body 1, nozzle body 1 is arranged on drill bit by screw thread 2; Conduit wall in described nozzle body 1 offers many guiding gutters 3, the cross section of guiding gutter 3 is U-shaped, and on the conduit wall of staying in the shape of a spiral in nozzle body 1, the quantity of guiding gutter 3 is 4, and uniform intervals is distributed in nozzle body 1, the high-pressure slurry stream ejected by guiding gutter 3 and current are with certain helicity, and there is centrostigma the moment of clashing into rock stratum, has certain destructive power to rock stratum; Described nozzle body 1 is shaping by carborundum one-step casting, and nozzle body 1 outer covering double layer of metal film, wherein internal layer is copper film, skin is nickel film, because carborundum hardness is higher than the conventional nozzle material such as steel, tungsten alloy, thus considerably increase the hardness of this nozzle, enable the hardness of this nozzle reach 20 times of steel nozzle on market, substantially prolongs the application life of nozzle; This nozzle hardness is high, can be applicable to the various environment such as oil field, gas field.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this manual is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of manual is only for clarity sake, those skilled in the art should by manual integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
