Description

Technical Field

[0001] The utility model belongs to the technical field of petroleum engineering, and particularly relates to a drill tool connection and disconnection device for petroleum engineering. Background Technique

[0002] The drill tools used in petroleum engineering generally include drill pipes and drill bits. The drill pipes are generally connected in multiple sections, and the tail of each drill pipe is threaded. The drilling rig equipment on the ground and the drill grinding equipment or bottom hole devices at the bottom of the well are all connected by drill pipes. The drill pipes can transport the drilling mud to the drill bit. At the same time, the drill pipes rotate together with the drill bit to lower or raise the bottom hole device. The drill pipes have strong mechanical properties and can withstand huge torques, bending moments, internal and external pressures, and high-frequency vibrations. In petroleum exploitation engineering, the drill pipes can generally be used multiple times.

[0003] In the existing related technologies, calipers are mostly used to clamp the drill pipes for connection and disconnection, and the drill tools cannot be straightened. Therefore, it is urgent to design a drill tool connection and disconnection device for petroleum engineering to solve these problems. Content of the Utility Model
