Description
Technical field
The present invention relates to drill pipe art, be specifically related to a kind of 14-3/4 inch super large caliber Prospection drill rod.
Background technology
In recent years, the price of gold and diamond continues to skyrocket, the mining amount making gold ore deposit relevant to diamond mine increases gradually, and the degree of depth of exploitation and width increase gradually, by 3 initial rice diameters, 7.5 rice diameters till now, more strict to the performance requirement of drilling tool, need larger bearing capacity and anti-twisting property.At present, the mine drilling rod of largest domestic bore is 6 inches, and the most frequently used is 9 ~ 10 inches in the world.Nowadays, many rig contractors are at transformation and upgrade drilling equipment or manufacture new rig, and these rigs brill is wide reaches more than 8 meters, bores so wide entering, needs a large amount of investments and the Ultradeep Drilling Technology of advanced person.
Summary of the invention
The object of this invention is to provide a kind of anti-twisting property strengthening probing drilling rod, improve the effective width of probing, and the final 14-3/4 inch super large caliber Prospection drill rod improving drilling efficiency.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: a kind of 14-3/4 inch super large caliber Prospection drill rod, comprise the drilling rod body with through hole, one end of described drilling rod body is male end, the other end of described drilling rod body is female end, and the screw thread of described male end and female end has tapering, the conical surface path of described male end is 264 ~ 266mm, the large footpath of the conical surface of described male end is 282 ~ 285mm, and the conical surface length of described male end is 219 ~ 221mm; The outside of described female end is provided with reamer hole, and large footpath, described reamer hole is 284 ~ 286mm; The taper hole path of described female end is 253 ~ 255mm, and the large footpath of taper hole of described female end is 272 ~ 274mm, and the taper hole length of described female end is 194 ~ 196mm.
Further, the screw thread effective length of described male end is 189 ~ 191mm.
Further, the screw thread effective length of described female end is 194 ~ 196mm.
The present invention has following beneficial effect: a kind of 14-3/4 inch super large caliber Prospection drill rod of the present invention, comprise the drilling rod body with through hole, one end of described drilling rod body is male end, the other end of described drilling rod body is female end, and the screw thread of described male end and female end has tapering, and external screw thread and internal thread are matched, thus make the connection between drilling rod more tight, firm; And the increase of bore enhances the anti-twisting property of probing drilling rod, improves the effective width of probing, improves recoverable reserves, shorten the probing cycle, extend the application life of drilling tool.
