摘要
介绍了国内外评价地热资源的方法 :1用容积法 (热储法 )计算地热资源量 ;2用解析法和数值法求解描述热水流动和热量运移的数学模型 ,模拟和预测地下热水系统的水动力场和温度场的时空变化。这些模型既有稳定流的 ,也有非稳定流的 ,并已从一维模型发展到二维模型再到三维模型。描述地下热水流动和热量运移的三维非稳定流模型 ,是目前流行和先进的数学模型。
Methods of evaluation of geothermal resources used at home and abroad are based on ① a volumetric approach to calculate values of geothermal resource and ② analytical and numerical methods to solve mathematical models that describe water flow and heat transport and to simulate and predict spatial and temporal changes in hydraulic heads and temperatures of a geothermal system.These models are either steady or unsteady.They have been developed from one dimension to two dimension and to three dimension.It proves that the three dimensional unsteady mathematical models to describe simultaneously geothermal water flow and heat transport are prevailing and advanced.
