Pipe following drilling tools, as the name suggests, means that the casing follows the drilling tool at the same time. The casing plays a role in protecting the wall and avoiding hole collapse in the process of hole forming. At present, the pipe following drilling tools in the market mainly include three series: eccentric pipe following drilling tools, concentric pipe following drilling tools and double power head rotary impact drilling tools. Black Diamond pipe following drilling tools also belong to these three series, in which concentric pipe following drilling tools include three sub series: reaming sleeve type, sliding block type and rotor type
