Abstract (en)
[origin: WO2015028554A1] The invention relates to a fracturing tube system (1) for introducing into a borehole in order to carry out a hydraulic and/or pneumatic fracturing process, comprising a plurality of tube lines (10). The fracturing tube system is to be designed such that it can be produced in a simpler and more economical manner and such that a variable total length of the fracturing tube system can be introduced into a borehole with little effort. This is achieved in that the fracturing tube system (1) comprises at least one traction cable (11), multiple coupling devices (12) which can be removably attached to the at least one traction cable (11), and multiple tube sections (100) which are separate from one another and which can be coupled to the coupling devices (12) in a pressure-tight manner and thus form the tube lines (10) as a whole. A pressure-tight releasable connection of the tube sections (100) to feedthroughs (120) of the coupling device (12) can be achieved so that fluid can be conducted from one tube section (100) into a subsequent tube section (100) through the feedthrough in the coupling device (12) in a tube-free manner.
