| | The terrestrial heat is one of the wide utilized energy resources, which is cheap and clean. Based on the distribution, gross and characteristic of Tianjin terrestrial heat resources, this paper analyzed the utilizable actuality and existent problem of Tianjin terrestrial heat resources. Then it discussed the countermeasures to strengthen the composed utilization of the terrestrial heat resources. sheltered exploitation. the industrialization of resources utilization and so on. | | 以天津地热资源的分布、总量和特点为基础、分析天津地热资源利用中存在的问题.讨论了加强地热资源综合利用、保护性开发和地热资源利用的产业化等对策。 | | 文摘来源 | | Geothermal resources is very rich in Tianjin,and exploited about 25.64 Mm~3 every year.There has been 269 geothermal wells in the end of 2005.The highest use rate of geothermal resources is 62.4% and the re-injection rate of geothermal used water is less than 8%.Based on the present situation of geothermal development and the characters of different reservoirs,analyses the problems such as lacking of use plan,the low geothermal use rate and the less re-injection amount,some proper using ways are put forward... | | 天津地区地热资源十分丰富,至2005年底,已有地热井269眼,年开采量2 564万m3。但地热资源利用率最高为62.4%,地热尾水回灌率不到8%,是一种粗放的开发利用模式。笔者从实现地热资源可持续开发利用角度出发,针对天津地区不同热储层的特征,在阐述天津地热资源开发利用现状的基础上,针对所存在的缺乏统一规划、地热利用率低和回灌量少等问题,针对不同的开采类型区制订了相应的保护措施及保护目标,提出了分区管理、总量控制、强度控制、利用方式控制和优化配置的保护原则,为有限、宝贵的地热水可持续开发利用提供技术保证;并提出地热资源必须走回灌开发道路,增加回灌井,提高回灌率是实现地热资源可持续开发利用的重要保障。 | | 文摘来源 | |   |
