DUAL MODE FRACTURE TOOL AND METHODS THEREFOR

Resumen de: WO2025079002A1

A fissure with controlled geometry is formed in hot dry rock by iterative application of increasing mechanical and hydraulic stresses in which the mechanical stress is applied by a contact device with typically opposing contact elements to incrementally open a mouth portion of the fissure while the hydraulic stress is used to then expand the fissure. However, it is also contemplated that the contact device may also be used for expansion and/or propagation of existing fissures that are naturally occurring or initiated by hydraulic fracturing. Fissures created with the devices and methods presented herein will avoid thermal bottlenecks in thermally conductive materials placed within such fissures. Moreover, the wide mouth portion of such fissures will help ensure continuous heat transfer from the thermally conductive materials placed within such fissures to a thermally conductive materials placed within a wellbore from which the fissures originate.

GEOTHERMAL EXPLOITATION SYSTEM

Resumen de: WO2025077225A1

Disclosed in the embodiments of the present application is a geothermal exploitation system, comprising an interference-free well, an exploitation well and a recharge well, the recharge well being located upstream of the interference-free well, and the exploitation well being located downstream of the interference-free well. This solution combines two geothermal exploitation techniques, i.e., water extraction and recharge and interference-free well heat exchange, but does not simply superpose the two techniques. Specifically, the hydraulic gradient of a heat storage flow field between upstream and downstream of the interference-free well can be further additionally increased while the exploitation well and the recharge well utilize geothermal energy, so as to increase the flow rate of underground water and promote the recovery of a geothermal field. As the flow rate of underground water of the heat storage flow field is increased, the heat exchange efficiency of an interference-free heat exchange system tends to gradually increase, and thus the phenomenon of heat and cold accumulation of the interference-free heat exchange system can be effectively alleviated.
