Abstract

The invention relates to the technical field of drill rods, in particular to an efficient spiral drill rod. The efficient spiral drill rod comprises a drill rod body and a connecting column, the connecting column is arranged at one end of the drill rod body, connecting through holes are formed in the connecting column and the side face of the other end of the drill rod body, the connecting through holes are polygonal through holes, connecting seats are arranged on the two sides of each connecting through hole, and connecting pins are arranged in the connecting through holes; and the connecting column is a polygonal column, a polygonal hole is formed in the drill rod body, and the polygonal column and the polygonal hole are correspondingly arranged. Hexagonal columns and inner hexagonal through holes are correspondingly formed in the connecting column and the drill rod body, so that relative rotation between the connected drill rods can be effectively prevented when the drill rods are connected.

Description

technical field [0001] The invention relates to the technical field of drill rods, in particular to high-efficiency helical drill rods. Background technique [0002] The drill pipe is a steel pipe with threads at the end, which is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or the bottom hole device at the bottom of the drilling well. The purpose of the drill pipe is to transport the drilling mud to the drill bit and together with the drill bit to raise, lower or rotate the bottom hole device. Drill pipe must be able to withstand enormous internal and external pressure, twisting, bending and vibration. In the process of oil and gas extraction and refining, the drill pipe can be used many times. The existing drill pipes are connected by pins, the connection method is simple, and the application is extensive. However, the existing drill pipes do not have a secondary fixing structure after connection, and there is a certai...
