鲁北地区热储弹性释水系数计算方法探讨

在对裘布依、泰斯公式适用条件的讨论基础上,提出了利用稳定流抽水试验资料求解弹性释水系数的方法,解决了鲁北地区地热资源计算中弹性释水系统确定的难题。该方法首先利用裘布依公式及吉哈尔特经验公式联立求解热储含水层的渗透系数(K),在此基础上,根据稳定流抽水试验第一落程初始时间段的降深与时间的关系曲线,利用泰斯公式求解热储含水层的弹性释水系数。

Method Study on Measuring Elastic Storage Coefficient in Geothermal Reservori in Lubei Area

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 drawdown depth and time at the beginning of stable pumping experiment and using Theis equation,the elastic storage coefficient of water-bearing stratum is gained.
