Abstract
The utility model discloses a case-hardened petroleum drilling tool, which belongs to a drilling tool. The case-hardened petroleum drilling tool structurally comprises a drill collar, a drill stem and a drill bit. The drill stem is arranged between the drill collar and the drill bit. The surface of the drill stem is provided with a hardened layer. Compared with the prior art, the case-hardened petroleum drilling tool has the characteristics of being designed reasonably, simple structure, being processed easily, low manufacturing cost, long performance life and so on.
Description
Technical field
The utility model relates to a kind of petroleum industry boring tool, specifically a kind of case-hardened oil drilling tools of handling through laser hardening.
Background technology
At present, after case-hardened oil drilling tools production moulding,, steel cause the reason of bulk deformation owing to expanding with heat and contract with cold, the manufacturer has selected to abandon the production technology of piece surface cure process, thereby shortened the application life of case-hardened oil drilling tools greatly, increased the cost of oil exploration industry greatly.
Summary of the invention
Technical assignment of the present utility model is at above weak point, provides that a kind of cost of production is low, a kind of case-hardened oil drilling tools of long service life.
The technical scheme that its technical problem that solves the utility model adopts is: this drilling tool comprises drill collar, drilling rod and drill bit, and drilling rod is arranged between drill collar and the drill bit, and the surface of drilling rod is provided with hardened layer.
The hardened layer that the surface of drilling rod is provided with is a spiral shape; The sclerosis bed thickness 2-3mm that the drilling rod surface is provided with.
A kind of case-hardened oil drilling tools of the present utility model is compared with prior art, has following characteristics:
1, the utility model has improved the production efficiency of manufacturing enterprise, has reduced cost consumption; 2, the case-hardened oil drilling tools of this laser hardening processing has also reduced the cost of production of enterprise because the raising of product surface hardness has prolonged the case-hardened oil drilling tools life-span in use greatly.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is a kind of structural representation of case-hardened oil drilling tools.
Among the figure: 1, drill collar, 2, drilling rod, 3, drill bit, 4, hardened layer.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
A kind of case-hardened oil drilling tools of the present utility model, its structure comprises drill collar 1, drilling rod 2 and drill bit 3, and drilling rod 2 is arranged between drill collar 1 and the drill bit 3, and the surface of drilling rod 2 is provided with hardened layer 4.Hardened layer 4 is a spiral shape; And hardened layer 4 thickness are between 2-3mm.
Specific practice is: utilize laser that the position that case-hardened oil drilling tools surface needs to increase hardness is scanned, utilize the high temperature action of laser, just can dissolve and condense rapidly in the metal surface, make the crystal grain in the melt metal not have the rise time, reach the purpose of crystal grain thinning, thereby make case-hardened oil drilling tools surface that good hardness be arranged, drilling tool itself has good plasticity again.
Through the chrome-moly steel hardened layer that laser hardening is handled, hardness never cure process Ka Shi 31.4 bring up to 54.1 of Ka Shi.
A kind of its processing and fabricating of case-hardened oil drilling tools of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of manual, be the known technology of those skilled in the art.
