Abstract: Dry hot rock, as a novel clean energy source, holds the potential to reduce carbon emissions effectively and mitigate the fossil energy shortage issue. The casing-cement sheath interface is the weaker component within the entire well system, and the mechanism behind the rupture of this interface under the coupled thermal-hydraulic-mechanical interaction remains unclear. This paper considers the thermal-poroelastic model of the casing-interface-cement sheath-formation in dry hot rock geothermal w... More
