Abstract (en)
[origin: WO2010083803A2] The invention relates to an apparatus for a pipe string of a geological drill hole, comprising a pipe string element and a fluid feed line, which is arranged outside of the pipe string element, extends along the pipe string element and is connected to a fluid injection device at the pipe string element by way of which a fluid fed through the fluid feed line can be introduced into an inner chamber of the pipe string element. The invention further relates to a pipe string of a geological drill hole, in particular a geothermal drill hole, to a method for operating a geological drilling gear, and to a method for producing a pipe string for a geological drill hole.
