摘要

•A numerical model of the 950–1350 m fractured granite reservoir through horizontal wells is established.•Desirable electricity production performance can be obtained under suitable conditions.•The system attains an electric power of 26.9–24.3 MW with an efficiency of about 50.10–22.39.•Electric power mainly depends on water production rate and injection temperature.•Higher permeability within a certain range is favorable for electricity generation.
