Abstract
The invention relates to the technical field of exploration drill rods, in particular to an exploration drill rod thread structure with an 11-1/4-inch ultra-large caliber. The exploration drill rod thread structure comprises external threads and internal threads, wherein the external threads are composed of external thread units, the internal threads are composed of internal thread units, the external thread units are composed of first roots and external thread teeth, the internal thread units are composed of second roots and internal thread teeth, the shapes of the external thread teeth and the internal thread teeth mutually correspond, and the external thread teeth and the internal thread teeth are in a symmetrical structure. Because the structure is adopted by the exploration drill rod thread structure, the drill rods can be tightly and firmly connected, the depth and the width of the drill rods can be effectively increased, and the drilling efficiency is increased. Additionally, the torsion resistant capability of the drill rods is increased because the caliber is increased, i.e., the connecting capability of the rotating shoulders of the drill rods is enhanced, and the safety and the stability of the drill rods are guaranteed. The development and use of the exploration drill rod thread structure play a positive role in improving the ultra-deep and ultra-wide drilling technology, and the extension drilling capability marked by large-displacement well drilling on a global scale is greatly increased.
