The understanding of the coupled thermo-hydro-mechanical behaviour of fault zones in naturally fractured reservoirs is of fundamental importance for a variety of societal and economic reasons, such as the sustainable energy transition for the safe use of natural resources. The idea here is to carry out a thermally controlled in situ fluid injection experiment in one of the faults accessible from the Tournemire underground research laboratory in Southern France. A heating system will be installed around the injection and enable a precise and controlled incremental increase the thermal load. In addition, an important monitoring system will be installed to measure the seismic and aseismic events as well as temperature evolution. A series of laboratory experiments will be conducted to understand the chemical and structural evolution occurring within fault zones during thermal and hydraulic loading.

了解天然裂缝性储层中断裂带的热-水-力学耦合行为对各种社会和经济原因具有重要意义，例如对自然资源安全利用的可持续能源转换。这里的想法是在法国南部Tournemire地下研究实验室可到达的断层之一进行热控制的原位流体注入实验。加热系统将安装在喷射器周围，以实现精确和可控的热负荷增量增加。此外，还将安装一个重要的监测系统来测量地震和地震事件以及温度演变。将进行一系列的实验室实验，以了解在热载荷和水力载荷作用下断裂带内发生的化学和结构演化。
