Abstract
The utility model provides a drill rod with double conical surface clamping tables. The drill rod comprises a drill rod body and the two conical surface clamping tables of a drill rod female joint. The conical surface clamping tables of the drill rod are sequentially arranged in the same direction. A pipe body transition section is arranged between the two conical surface clamping tables. The length of the pipe body transition section is 1.5-3.5 times the diameter of the drill rod body and is 200-460mm. The included angle between the conical surface of each conical surface clamping table and the outer surface of the drill rod body is 10-90 degrees, and a cylinder is arranged between the conical surfaces of the conical surface clamping tables and the pipe body transition section. The drill rod has the advantages that the structure is simple, putting out of a hole and running in the hole are safe, mechanical production can be finished, damage to the exterior of the drill rod is small, and safe use is not influenced.
Description
Technical field
The utility model relates to a kind of oil drilling equipment, especially a kind of drilling rod.
Background technology
The female joint end of oil drill rocker is generally provided with Ka Tai, to adapt to elevator operation.In drilling process, while pulling out of hole lower boring, elevator is contained in to Ka Tai upper, so that drilling rod is fixed on offshore boring island.It is unreasonable that this tool joint is connected operation in the time pulling out of hole with lower brill, and operating efficiency is low, and labour intensity is large, serious to the damage of drilling rod body.After wearing and tearing,, there is potential safety hazard in the attenuation of drilling rod wall.
Utility model content
The purpose of this utility model is to avoid the deficiencies in the prior art and a kind of Double-conical-surface card bench drill bar is provided.
The technical solution of the utility model comprises: Double-conical-surface card bench drill bar, and described drilling rod comprises two conical surface Ka Tai of drilling rod body and tool joint box, the conical surface Ka Tai of described drilling rod sets gradually; Two conical surface Ka Tai are for arranging in the same way, between two conical surface card platforms, it is body changeover portion, the length of body changeover portion is 1.5-3.5 times of drilling rod body diameter, the length of body changeover portion is 200-460mm, the angle of the conical surface of described conical surface Ka Tai and this external surface of drilling rod is 10 °-90 °, between the conical surface of conical surface Ka Tai and body changeover portion, be cylinder, described cylinder length is 35-60mm.
The length of body changeover portion is 380mm.
The angle of the conical surface of described conical surface Ka Tai and this external surface of drilling rod is 18 °.
Described conical surface Ka Tai is right angle shoulder.
Body changeover portion place drill pipe diameter is greater than drilling rod body diameter.
The utility model has the advantage of simple in structurely, pull out of hole, lower brill safety, can complete mechanization production, and little to the outer damage of drilling rod, do not affect safe handling.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Double-conical-surface card bench drill bar, described drilling rod comprises two conical surface card platforms 1 and 3 of drilling rod body 5 and tool joint box, the conical surface card platform 1 and 3 of described drilling rod sets gradually; Two conical surface card platforms 1 and 3 are for arranging in the same way, between two conical surface card platforms 1 and 3, it is body changeover portion 2, the length of body changeover portion 2 is 1.5-3.5 times of drilling rod body 5 diameters, the length of body changeover portion 2 is 200-460mm, the angle of the conical surface of described conical surface Ka Tai and this external surface of drilling rod is 10 °-90 °, between the conical surface of conical surface card platform 3 and body changeover portion 2, be cylinder, described cylinder length is 35-60mm.
The length of body changeover portion 2 is 380mm.
The angle of the conical surface of described conical surface card platform 3 and drilling rod body 5 external surfaces is 18 °.
Described conical surface card platform 3 is right angle shoulder.
