文摘
- •
EGS reservoir simulation with thermo-hydro-mechanical coupling was carried out.
- •
Hydraulic conductivity is enhanced due to the thermal stress during production.
- •
Permeability and porosity play major role in terms of the productivity.
- •
For a vertical fracture, increasing fracture thickness improves the productivity.
- •
For vertical wells, production wells should be deeper than injection well.
