Description

Technical Field

[0001] This utility model relates to the field of cable drill rod technology, specifically a cable drill rod with a miniature plug. Background Technology

[0002] Cable-through drill pipe is a special type of drill pipe used in directional drilling. It not only has the function of ordinary drill pipe in transmitting torque and axial force to achieve drilling, but also allows signal cables (used to transmit downhole measurement data and other signals) to pass through the inside of the drill pipe, thereby ensuring signal transmission between downhole measuring instruments (such as drilling rigs) and surface equipment during the drilling process.

[0003] Cable-through drill rods, as a special type of drill rod used in directional drilling, play a crucial role. However, existing cable-through drill rods suffer from low threaded connection strength and poor wear resistance, as well as inconvenient disassembly and maintenance due to the way the insulated head is connected, resulting in certain inconveniences. Based on this, a cable-through drill rod with a miniature plug is proposed. Utility Model Content
