Based on the analysis of suitable conditon on applying Dupuit and Theis equations,method for gaining storage coefficient by using the datas obtained from steady-flow pumping test is put forward in this paper,which will solute the problem for determining elasitc storage coefficient difficultly in geothermal resource measurement in Lubei area.First,using Dupuit and Theis equations to gain the peneration coefficient(K) of water-bearing stratum in geothermal reservoir.Then,according to relation curve of drawdow...
