Novel drill rod joint thread

The utility model relates to a novel drill rod joint thread. The technical scheme adopted by the utility model is as follows: the novel drill rod joint thread comprises joint bodies; the upper ends of the joint bodies are provided with internal threads; the lower ends of the joint bodies are provided with external threads; and thread parameters, such as thread pitch and tooth height, of the internal threads and the external threads are increased to 1.2-1.3 times that of a standard thread by the same proportion according to the thread with the thread profile of V-0.038 and the taper of 1/6 in the API 7-2 standard, the taper and an included angle of thread are unchanged, and the numbers of the thread teeth of the internal threads and the external threads can be appropriately reduced or unchanged. Compared with the prior art, the novel drill rod joint thread has the advantages of simple structure, convenience in operation, and effectiveness in the decrease or avoidance of thread gluing phenomenon, the screwing-on is easy, and the service life is long, so that the novel drill rod joint thread can be conveniently and widely applied to the field of oil and natural gas drilling and the trenchless field.
