开封市地热系统特征

Geothermal field characteristics in the Kaifeng city

  • 摘要: 以28眼地热井水温资料为基础,研究了开封市地热系统的地温、地温梯度及地表热流值的分布特征及控制因素.结合钻孔柱状和地热水动态资料,划分了亚热储层,并说明了各亚热储层地热水之间的相互关系及水文地质特征.依据地热水水质化验结果,评价了各亚热储层地热水的水化学特征.利用放射性同位素14C法,估算了各热储层地热水的年龄和循环速率并确定了补给源.

     

    Abstract: This paper studies the distributing characteristics and the controlling factors of ground temperature,geothermal gradient and surface geothermal current value by using the data of 28 geothermal wells in the Kaifeng geothermal field.Dividing the reservoir(depth 300~1 600 m)into 6 sub-reservoirs,the hydraulic-connection among sub-reservoir is researched also.The hydro-geological characteristics and hydrochemical characteristics of 6 sub reservoirs are assessed.The age,the circulating rate and the recharge area of geothermal groundwater are determined based on the radioactive isotope 14C content.
