Abstract
The invention discloses a protective petroleum drill rod which comprises a rod body. A conical pipe joint is mounted on the inner side face of the rod body, the inner side of the conical pipe joint is connected with a conical pipe, the conical pipe and the conical pipe joint are connected through a reinforcing bolt, a flat groove is formed in a position, close to the middle, of each of the upper surface and the lower surface of the rod body, a docking head is mounted at the end of the rod body along the length direction of the conical pipe and arranged in a manner of penetrating the conical pipe, a docking head shoulder is connected to each of the top and the bottom of the docking head and detachably connected onto the docking head, a drill bit is mounted on the side wall of the docking head and mechanically connected on the docking head, a drill bit jacket coats the surface of the drill bit, and one end, opposite to the conical pipe joint, of the conical pipe is hermetically connected with the inner side face of the drill bit. The protective petroleum drill rod is compact in structure, has good protecting performance and is convenient to connect and extremely high in wear resistance, components are connected and are less prone to shedding, and service life of the drill rod can be prolonged.
Description
Technical field
The present invention relates to a kind of drilling rod, particularly one protection oil drill rocker.
Background technology
Under normal geological conditions, the oil drilling degree of depth reaches thousands of rice, it is dark that Special section can reach myriametre, usual about the 10 meters length of drilling rod for oil drilling, along with drilling depth increase joint is linked in sequence the long drilling rod of scale, the most complex structure of present oil drill rocker, it is very inconvenient to couple together, connector easily lost efficacy, cost is also higher simultaneously, oil drill rocker is indispensable important tool in oil drilling operation, because the oil drilling degree of depth is general darker, many drilling rods connection guarantees are needed normally to creep into along with drilling depth increases, the oil drill rocker mostly complicated structure of current use, it is very inconvenient to couple together, and connector easily lost efficacy, be unfavorable for the raising of drillng operation efficiency.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the problems referred to above, provides a kind of compact conformation, connects the protection oil drill rocker not easily occurring obscission between component.
To achieve these goals, the technical solution used in the present invention is such: protection oil drill rocker of the present invention, comprise the body of rod, body of rod medial surface is provided with Taper Pipe joint, a Taper Pipe is connected inside Taper Pipe joint, be connected by strengthening stud between Taper Pipe with canalis spinalis joint, body of rod upper surface and soffit are equipped with near center and rise as high as the banks, rod end is provided with butt joint along Taper Pipe length direction, butt joint is arranged through Taper Pipe, butt joint top and bottom are all connected with butt joint shoulder, butt joint shoulder is detachably connected in butt joint, butt joint side is provided with drill bit, drill bit is mechanically connected in butt joint, bit face is coated with drill bit sheath, one end and the drill bit medial surface of the relative Taper Pipe joint of Taper Pipe are tightly connected.
Further, as a kind of concrete form of structure, between Taper Pipe joint of the present invention and the body of rod, be connected with wear-resisting shaft.
Further, as a kind of concrete form of structure, between Taper Pipe of the present invention with canalis spinalis joint, threaded engagement is connected.
Further, as a kind of concrete form of structure, between butt joint of the present invention and butt joint shoulder, compression member is connected with.
Further, as a kind of concrete form of structure, drill bit jacket surface of the present invention is coated with wearproof structural tier.
Further, as a kind of concrete form of structure, drill bit sheath of the present invention adopts corrosion-resistant material to make.
Further, as a kind of concrete form of structure, the built-in stiffener of drill bit of the present invention.
Compared with prior art, the invention has the advantages that: this protection oil jackrod structure is compact, connect and not easily occur obscission between component, have good barrier propterty, easy to connect, abrasion resistance is extremely strong, can extend the application life of drilling rod.
