【Summary】1, the cleaning part adopts closed protective structure, clean environment and ensure safety.
1, the cleaning part adopts closed protective structure, clean environment and ensure safety.
2, the external cleaning of the rod adopts the inclined roller to rotate forward, frequency conversion speed regulation, rotation and promotion speed can be adjusted.
3, the use of PLC detection and control system, manual and automatic two control methods (can be designed according to user requirements).
4, increase the drilling pipe external cleaning using medium frequency induction heating pipe surface, after the rotating steel brush cleaning, rinse with water, and then through the rust box for rust removal, pipe surface heating temperature controllable and adjustable, not affected by the seasonal temperature, cleaning and rust at the same time to complete the effect.
The kelly pipe is located at the upper end of the drill string, and its main role is to transfer the torque and withstand the total amount of the drill string. The end face of the drive part of the kelly pipe is divided into square and hexagon, the more square is used in oil drilling, and the water eye is a regular hexagon, because the wall thickness is about three times that of the drill pipe, and is made of high-strength alloy steel, so it has high tensile strength and torsional strength.MORE
The drill pipe is the hub connecting the surface and the underground. In rotary drilling, the drill string is used to transfer the energy needed to break rock, apply weight on bit to the bottom of the well, and transport drilling fluid in the well. When drilling with downhole power drilling tools, it withstands the reverse torque of downhole power drilling tools and delivers liquid energy to downhole power drilling tools at the same time.MORE
