| 英文摘要 | yangbajing geothermal field is the first high-temperature hydrothermal convective geothermal system in china. research and development of the deep fractured granite reservoir is of great importance for capacity expanding and sustaining of the ground power plant. the geological exploration found that there is a fractured granite heat reservoir at depth of 950-1350 m in well zk4001 in the north of the geothermal field, with an average temperature of 248 degrees c and a pressure of 8.01-11.57 mpa. in this work, electricity generation potential and its dependent factors from this fractured granite reservoir by water circulating through vertical wells are numerically investigated. the results indicate that the vertical well system attains an electric power of 16.8-14.7 mw, a reservoir impedance of 0.29-0.46 mpa/(kg/s) and an energy efficiency of about 29.6-12.8 during an exploiting period of 50 years under reference conditions, showing good heat production performance. the main parameters affecting the electric power are water production rate and injection temperature. the main parameters affecting reservoir impedance are reservoir permeability, injection temperature and water production rate. the main parameters affecting the energy efficiency are reservoir permeability, injection temperature and water production rate. higher reservoir permeability or more reasonable injection temperature or water production rate within certain ranges will be favorable for improving the electricity generation performance.
