Abstract
The utility model relates to a screw thread spray nozzle for a diamond drill bit and belongs to the field of a part of oil drilling equipment. The screw thread spray nozzle is formed by a spray nozzle body; the spray nozzle body is a trapezoidal cylinder; a flared jet flow passage is arranged inside the spray nozzle body; the periphery of the top of the spray nozzle body is provided with spray nozzle pillars at intervals; and the spray nozzle body below the spray nozzle pillars is provided with an external screw thread. In the working process of the screw thread spray nozzle, by the jet flow passage formed inside the spray nozzle body, cleaning capacity and auxiliary rock breaking capacity of jet flow on a shaft bottom can be improved and a drill bit is prevented from being balled up or rock debris are prevented from being repeatedly broken up, and thus, the drilling speed is improved, drilling cost is reduced and no influence is generated on a cooling effect of a clad sheet. The screw thread spray nozzle solves the problem that due to the structure, an existing spray nozzle has a certain influence on the cooling effect of the clad sheet in the actual working process, so that the drilling speed is reduced and the short service life of the spray nozzle is caused.
Description
Technical field
The utility model relates to a kind of threaded nozzle for diamond bit, belongs to the oil drilling equipment field of components.
Background technology
Oil gas field is in drilling process, and the nozzle that uses on the diamond bit has short nozzle, middle long nozzle, extended jet nozzle and oblique nozzle etc.; These nozzles are to improve jet to cleansing power and the auxiliary drill bit fractured rock of shaft bottom landwaste, are unique passages that petroleum drilling fluid sprays.Existing nozzle is made by Hardmetal materials mostly, because reasons in structure, its cooling effect to composite sheet in real work has certain influence, thereby has reduced rate of penetration, and causes the application life of nozzle shorter.
Summary of the invention
The purpose of this utility model is: provide a kind of simple in structure, the cooling effect to composite sheet in real work does not exert an influence, and the threaded nozzle that is used for diamond bit that has improved rate of penetration, prolonged application life.
The technical solution of the utility model is:
A kind of threaded nozzle for diamond bit, it is made of nozzle body, nozzle body is a trapezoidal cylinder, it is characterized in that: nozzle body inside is provided with the jet road, be arranged at intervals with the nozzle post on the nozzle body top circumference, the nozzle body of nozzle post below is provided with external screw thread, described nozzle body height 35mm, the nozzle body external diameter is 25.2mm
Described jet road flare, the bore of jet road big opening end is 15.8mm, the bore of jet road osculum end is 8mm.
The beneficial effects of the utility model are:
The threaded nozzle that should be used for diamond bit is simple in structure, in the course of work, the inner jet road that arranges of nozzle body, can improve jet to cleansing power and the auxiliary rock ability in shaft bottom, avoid bit balling or repeat broken landwaste, therefore improved rate of penetration, reduced drilling cost, prolonged the application life of nozzle, and the cooling effect of composite sheet has not been exerted an influence.Solved existing nozzle owing to reasons in structure, the cooling effect to composite sheet in real work has certain influence, thereby has reduced rate of penetration, and causes nozzle short problem in application life.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional structure schematic diagram of the present utility model.
Among the figure: 1, nozzle body, 2, the jet road, 3, the nozzle post, 4, external screw thread.
The specific embodiment
The threaded nozzle that should be used for diamond bit is made of nozzle body 1, and nozzle body 1 is a trapezoidal cylinder, nozzle body 1 height 35mm, and nozzle body 1 external diameter is 25.2 mm.Nozzle body 1 inside is provided with trumpet-shaped jet road 2, and the bore of jet road 2 big opening ends is 15.8mm, and the bore of jet road 2 osculum ends is 8mm.
Be arranged at intervals with nozzle post 3 on nozzle body 1 top circumference, the nozzle body 1 of nozzle post 3 belows is provided with external screw thread 4.
During this threaded nozzle work, because the jet that from nozzle body 1, comes out, can vertically act on the shaft bottom by the nozzle body 1 inner jet road 2 that arranges, therefore can improve jet to cleansing power and the auxiliary rock ability in shaft bottom, avoid bit balling or repeat broken landwaste, thereby improved rate of penetration, reduced drilling cost, prolonged the application life of nozzle simultaneously, and the cooling effect of composite sheet has not been exerted an influence.Solved existing nozzle owing to reasons in structure, the cooling effect to composite sheet in real work has certain influence, thereby has reduced rate of penetration, and causes nozzle short problem in application life.
