| 摘 要： | 针对因地热水位动态资料不足而导致的水量计算结果偏离实际的状况，以天津地热田雾迷山组热储层为例，建立了利用放射性同位素^14C资料进行地热水量计算的有限混合网络模型，并利用1998—2001年的水位、水量及^14C资料进行了模型的识别，得到了有效孔隙度和弹性释水率等水文地质参数，利用所建立的模型及水文地质参数计算了地热水的储存量及补给量。研究表明，地热水的开采主要是消耗弹性储量。 |
| 关 键 词： | 地热水量 有限混合网络模型 放射性同位素14C |

| Abstract: | Because of lack of geothermal water level data, calculation of water amount with numerical models are not as accurate as expected. Exemplified by the geothermal aquifer of the Wumishan Group in the Tianjin geothermal field, a finite state mixed cell model based on ^14C was established to calculate the amount of geothermal water. By identifying the model with the water level, amount and data of ^14C from 1998 to 2001, the effectual porosity and specific storage of the aquifer were calculated. With the established model and hydrogeological parameters, the storage capacity and recharge capacity of the geothermal water were calculated. The results show that most geothermal water has been exploited from the storage of the aquifer. |
| Keywords: | Amount of geothermal water finite state mixed cell model radioactive isotope of ^14C |
