Abstract
The utility model relates to a drill rod, which comprises a drill rod pipe body, a thickening section, an outer thread connector and an inner thread connector. Two ends of the drill rod pipe body are respectively connected with a thickening section, one thickening section is connected with an outer thread connector, and the other thickening section is connected with an inner thread connector. The thickening portions at two ends of the drill rod pipe body are far away from the drill rod connectors by welding the thickening sections, so that stress concentration of the thickening conical face disappearing portion of the drill rod pipe body can be reduced, service performance of the drill rod is improved, failure accidents are reduced, simultaneously maintenance recycle of the failure drill rod is achieved, and production cost of the drill rod is reduced.
Description
Technical field
The utility model relates to a kind of drilling rod, belongs to the oil and gas well drilling apparatus field.
Background technology
The drilling rod that uses in the oil and gas well drilling process at present is mainly by drill pipe body, and female adapter and male connection three parts are formed.The manufacturing approach of drilling rod has two kinds, and a kind of is monolithic, and a kind of is welded type.The manufacturing approach of integral drill rod be at the drill pipe body two ends respectively pier roughing go out female adapter and male connection, then pass through bulk heat treatmet, become integral drill rod.Because the restriction of being made equipment, the external diameter of integral drill rod generally is no more than 90mm at present.The manufacturing approach of welded type drilling rod is to process drill pipe body respectively earlier, female adapter and male connection, and then with drill pipe body, male connection and female adapter couple together through the mode of welding, produce a qualified welded type drilling rod.The welded type drilling rod is to use the widest drilling rod at present.Because the drill pipe body of welded type drilling rod and the size of tool joint differ bigger; In order to guarantee the performance of welding position; Need carry out pier to the drill pipe body two ends and slightly thicken processing; Because being the drill pipe body upper stresses, the variation of physical dimension, the inner conical surface of the thick structure thicker of drill pipe body end pier and position, body boundary concentrate the most serious position.In the drilling rod use, perforation or fracture failure very easily take place in inner conical surface and position, body boundary.According to present drilling rod manufacturing approach, drill pipe body thickening position takes place to lose efficacy and will cause whole drilling rod to be scrapped, and this has caused great waste.
Summary of the invention
The utility model provides a kind of drilling rod to the above-mentioned deficiency that existing drilling rod exists.
The technical scheme that the utility model solves the problems of the technologies described above is following: a kind of drilling rod comprises drill pipe body, thick section, male connection and female adapter; The two ends of said drill pipe body respectively are connected with a thick section; Be connected with male connection on one of them thick section, be connected with female adapter on another thick section.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, link to each other through weld seam between said drill pipe body and the thick section.
Further, link to each other through weld seam between said thick section and the male connection.
Further, connect through weld seam between said thick section and the female adapter.
Further, has connecting thread in the said male connection.
Further, has connecting thread in the said female adapter.
The beneficial effect of the utility model is: the utility model drilling rod is through the welding thick section; With the thickening position at drill pipe body two ends away from tool joint; Thereby the stress that reduces drill pipe body thickening conical surface disappearance position is concentrated, and improves drilling rod military service performance, reduces the generation of failure accidents; Realize repairing and reusing simultaneously, reduce the cost of production of drilling rod the inefficacy drilling rod.
Description of drawings
Fig. 1 is the structural representation of the utility model drilling rod.
The specific embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
As shown in Figure 1; Drilling rod is made up of drill pipe body 1, thick section 2, male connection 3 and female adapter 4, and the two ends of said drill pipe body 1 respectively are connected with a thick section 2, is connected with male connection 3 on one of them thick section 2; Be connected with female adapter 4 on another thick section 2; Connect with weld seam 5 between said drill pipe body 1 and two thick sections 2, connect with weld seam between thick section 2 and the male connection 3, connect with weld seam 5 between another one thick section 2 and the female adapter 4.Be processed with connecting thread 6 in the said male connection 3, be processed with connecting thread 7 in the said female adapter 4, said drilling rod is realized the connection between single through connecting thread 6 and 7.
The manufacturing approach of the utility model drilling rod is: (1) is carried out pier with certain-length drill pipe body two ends according to design size and is slightly thickeied, and quenches then+the high tempering processing, makes drill pipe body 1; (2) according to the thick section 2 of the internal diameter of welding position, drill pipe body 1 end and outside dimension processing certain-length, and to thick section 2 quench+high tempering handles, and guarantees that the mechanical property of thick section 2 is identical with drill pipe body 1; (3) male connection 3 of processing drilling rod and female adapter 4, and quench+the high tempering processing; (4) with the drill pipe body that processes 1, thick section 2, male connection 3 couples together with the method for female adapter 4 through welding; (5) butt welded seam 5 carries out temper earlier, eliminates welding stress, quenches then+the high tempering processing, guarantees that the mechanical property at weld seam 5 positions is not less than drill pipe body 1.
Utilize the drilling rod manufacturing approach can realize the drilling rod that drill pipe body thickening position takes place to lose efficacy is repaired, only need the inefficacy part of excision, carry out pier again and slightly thicken near pipe end, and the thick section 2 of welding appropriate length, just can realize reparation to the inefficacy drilling rod.The utility model drilling rod is through welding thick section 2; With the thickening position at drill pipe body 1 two ends away from tool joint; Thereby the stress that reduces drill pipe body thickening conical surface disappearance position is concentrated, and improves drilling rod military service performance, reduces the generation of failure accidents; Realize repairing and reusing simultaneously, reduce the cost of production of drilling rod the inefficacy drilling rod.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
