Abstract: Qicun geothermal field has been developed for more than 30 years.Water temperature drops quickly since large exploitation beganning in 1988.Conceptual model of Qicun geothermal field has been constructed and LUMPFIT is used to predict waterl evel drawdown under different production rates based on multiple well pumping test data as well as temperature prediction.Based on those predictions, reasonable development plan has been put forward, which is critical to future development of Qicun geothermal field.
