Technical Field

The invention relates to the technical field of drill rods, in particular to an integral spiral drill rod.

Background

The drill pipe is a threaded steel pipe at the end for connecting the surface equipment of the drilling machine and the drilling and milling equipment or bottom hole assembly at the bottom end of the drilled hole, the auger pipe is used to convey drilling mud to the drill bit and raise, lower or rotate the bottom hole assembly with the drill bit, and the auger pipe must be able to withstand significant internal and external pressures, twists, bends and vibrations. With the increasing demand, the requirement for the drill rod is higher and higher, but the existing auger rod still has the defect that sludge and the like attached to the inner wall of the drill rod cannot be conveniently and effectively removed, so that the integral auger rod is needed to solve the problems.

Disclosure of Invention
