TL;DR: In this paper, a series of studies were conducted to determine a suitable site for enhanced geothermal systems (EGSs) in mainland China, and a hydraulic fracturing model based on real geological and logging data of well YS-2 and field fracturing experience in this region was established, and the geometric dimension and flow conductivity of the induced fracture were imported into a 3D hydrothermal coupled model established using TOUGH2-EOS1.

TL;DR: In this article, a possible enhanced geothermal system and numerically investigated the effects of injection rate, well spacing, and injection temperature on the system performance, providing useful insight into hydraulic pressure, thermal production, and power generation processes for the Qiabuqia geothermal field.

TL;DR: In this article, the authors used the lab parameters and the GR1 well data from the Qiabuqia site to numerically investigate the reservoir stimulation and electricity generation from a three-horizontal-well EGS system created in the granitic reservoir at depth 3500-3700

TL;DR: In this paper, the effects of roughness and confining pressure on seepage characteristics were analyzed and the results indicated that large roughness in the direction parallel to flow would reduce effective heat transfer area.

TL;DR: In this article, a series of triaxial tests were conducted to investigate the effect of secondary damage on the reservoir secondary damage of hot dry rock, and the results indicated that the expansion direction of fracture turns from vertical to oblique and decreases to a single fracture plane.
