Description
Technical field
The utility model relates to the drilling rod of the drilling wells such as a kind of oil, natural gas and no-dig technique use, is specifically related to a kind of pipe end partial operation friction welding drilling rod.
Background technology
At present, at oil, in gas drilling and non-excavating construction process, drilling rod is as main drilling tool, cost drops into relatively large, conventional drilling rod mainly comprises end upsetting during fabrication, body heat treatment, body is detected a flaw, pipe end inner surface, external surface and facing processing, pipe end and tool joint friction welding, weld seam heat treatment, drilling rod weldering position, footpath fine finishining, the operations such as welding zone nondestructive testing, in pipe end, surperficial turnery processing need be carried out in thickening and external upset (EU) region, before turning, pipe end outside dimension is greater than finished product drill pipe elevator size about 4 ~ 6mm, pipe end internal diameter size is less than finished product drill pipe elevator internal diameter size about 4 ~ 6mm, therefore, large 4 ~ the 6mm of wall ratio finished product drill pipe elevator place wall thickness before tube end maching, end upsetting deflection is larger, in pipe end, intermediate zone shape controlling difficulty is high, end upsetting, the process costs such as body full heat treatment and tube end maching are higher, the total manufacturing cost of drilling rod is caused to drop into higher, operation is comparatively loaded down with trivial details.
Summary of the invention
The purpose of this utility model is exactly the defect existed for prior art, there is provided a kind of structure simple, cheap for manufacturing cost, in pipe end, intermediate zone shape is easy to control, stress dispersion is even, ensure the bonding strength of friction welding seam, difficulty of processing is low, the pipe end partial operation friction welding drilling rod of long service life.
Its technical scheme is: a kind of pipe end partial operation friction welding drilling rod, comprise drill pipe body, the upper end of described drill pipe body is provided with upset end, the lower end of described drill pipe body is provided with lower upset end, described upper upset end is consistent with drill pipe elevator inside/outside diameter size with the thickness of lower upset end, pipe end end face and the pipe end surfaces externally and internally of described drill pipe body are provided with partial operation region, the upper upset end of described drill pipe body connects tool joint box by friction welding, and the lower upset end of described drill pipe body connects tool joint pin by friction welding.
Described partial operation region be drill pipe body pipe end end face and thicken in be less than within the scope of 10mm pipe end apart from pipe end end face and external upset (EU) surperficial.
The utility model compared with prior art, has the following advantages: structure is simple, and cheap for manufacturing cost, in pipe end, intermediate zone shape is easy to control, and stress dispersion is even, and ensure the bonding strength of friction welding seam, difficulty of processing is low, long service life.

Fig. 2 is the partial enlarged drawing at friction welding seam place.
Detailed description of the invention
See figures.1.and.2, a kind of pipe end partial operation friction welding drilling rod, comprise drill pipe body 1, the upper end of described drill pipe body 1 is provided with upset end 2, the lower end of described drill pipe body 1 is provided with lower upset end 3, described upper upset end 2 is consistent with drill pipe elevator inside/outside diameter size with the thickness of lower upset end 3, pipe end end face and the pipe end surfaces externally and internally of described drill pipe body 1 are provided with partial operation region 8, the upper upset end 2 of described drill pipe body 1 connects tool joint box 4 by friction welding, the lower upset end 3 of described drill pipe body 1 connects tool joint pin 5 by friction welding.
Described partial operation region 8 be drill pipe body 1 pipe end end face and thicken in be less than within the scope of 10mm pipe end apart from pipe end end face and external upset (EU) surperficial.
Upset drill pipe body 1, upper upset end 2 and lower upset end 3 directly thicken to finished product drill pipe elevator inside/outside diameter size, at the end face of upper upset end 2 and lower upset end 3 with thicken in be less than within the scope of 10mm pipe end apart from end face and the partial operation region 8 on external upset (EU) surface, by turnery processing scale removal, upper upset end 2 connects tool joint box 4 by friction welding, and lower upset end 3 connects tool joint pin 5 by friction welding.By carrying out end face at upper upset end 2 and lower upset end 3 and surfaces externally and internally carries out partial operation in partial operation region 8, when upset end 2 and lower upset end 3 can be avoided to carry out friction welding with tool joint box 4 and tool joint pin 5, oxide skin enters the inside of friction welding seam 6 and lower friction welding seam 7, the bonding strength of friction welding seam 6 and lower friction welding seam 7 in impact, more than 15mm is about owing to welding shortening amount during friction welding, thus upper upset end 2 and lower upset end 3 are partial operation region 8 apart from the pipe end surfaces externally and internally that end face is less than within the scope of 10mm, extruded by inside and outside overlap 9 in friction welding process, and be distributed in friction welding seam 6 and lower friction welding seam 7 surfaces externally and internally.Through to after inside and outside upper friction welding seam 6 and lower friction welding seam 7, overlap carries out turnery processing and reconditioning, the inside/outside diameter size of upper upset end 2 and lower upset end 3 and the elevator size of tool joint box 4 and tool joint pin 5 are still consistent, through to operations such as upper friction welding seam 6 and the heat treatment of lower friction welding seam 7 welding region, welding zone nondestructive testings, namely complete drilling rod and manufacture overall process.Therefore, greatly reduce the wall thickness of upset end 2 and lower upset end 3 on end-thickened drill pipe body 1 and thicken difficulty, upper upset end 2 and lower upset end 3 internal upset transitionzone shape more easy to control, the process costs such as end upsetting, body full heat treatment and tube end maching obtain further reduction equally.
