| 摘 要： | 利用14C测年技术对驻马店市地热流体年龄进行计算,结合热储沉积时代、地热流体赋存深度可以判断流体补给来源、径流速度及可更新能力,对研究区域地热赋存规律、资源评价有重要意义。结果显示,驻马店市自西向东地热流体年龄从26ka增加到54ka,遂平县赋存深度1,400m的地热流体较上蔡县、汝南县、平舆县、新蔡县赋存深度1,000m的地热流体更为年轻,表明驻马店市地热流体以侧向缓慢径流为主,垂向交替作用极为微弱。在工程实践中,以不考虑侧向补给、垂向补给的弹性释水量作为地热流体的可开采量更为可靠。

| Abstract: | The geothermal fluid age of Zhumadian City have been calculated by 14C dating technique. In combination with the thermal reser- voir deposition time and the geothermal fluid occurrence depth,we can determine the source of fluid recharge, runoff velocity and renewable capability,So, it will be of great significance on the geothermal occurrence rules and resource assessment in study area.It was found that, the geothermal fluid were increased from 26 to 54 thousand years from west to east of Zhumadian City,the geothermal fluid with an occurrence depth of 1400m in Suiping County was younger than the depth of 1000m in Shangcai County,Runan County,Pingyu County and Xincai County, It was suggesting that the lateral slow runoff was the main flow pattern of the geothermal fluid of Zhumadian City,and the the vertical alternation effect was negligible.In engineering practice, It is more reliable when estimating the exploitable quantity of the geothermal fluid, the lateral and vertical recharge of the elasticity released water is ignored. |
