High-Pressure And High-Temperature Closed Geothermal Exchanger For A Magmatic Or Metamorphic Formation

摘要

The invention relates to a geothermal exchanger comprising a casing containing a heat-transfer fluid with which it is in direct contact. The casing is flexible such as to be in direct contact with a wall of the borehole containing the exchanger under the effect of the pressure of the heat-transfer fluid.
