Abstract:
Nowadays, there is no effective method to evaluate the efficiency of geothermal power plant but capacity test of in-situ. This is due to the poor-known thermal-fluid information about the reservoir. This study proposes an innovative Capacity Evaluation method based on the thermal resistance of well. The capacity evaluation model of geothermal well consists of the Brinkman model conjugated with heat transfer model and the pipe flow model. This capacity evaluation model is validated with the capacity test of the geothermal well of IC 09 & 13 in Chingshui, Taiwan. The thermal resistance of these wells can be obtained through the in-situ data of the geometry, well temperature, and mass flow rate. The capacity of geothermal can be optimized as the reasonable capacity evaluation model is built. In the thermal resistance view, the key technology will be proposed for building the reliable and convenient evaluated model of geothermal capacity.
