| 摘 要： | 天津是我国地热资源比较丰富、开发利用较早的城市之一,二十世纪九十年代以后开始大规模的将地热资源应用于供暖、洗浴、养殖等方面.目前全市地热供暖面积约1233万m2,是我国利用地热供暖规模最大的城市,并于2011年1月获得“中国温泉之都”荣誉称号.地热资源已经成为天津经济发展和改善城市环境质量不可多得的清洁能源.天津地区的主要热储层均已形成降落漏斗,明化镇组热储层在市区及新四区形成漏斗;大港区形成了本市馆陶组热储层最大的一个漏斗中心;雾迷山组热储层在市区形成了较大的降落漏斗.尽管天津地热资源丰富、开发利用程度较高,但在开发利用过程中存在很多问题,主要有水位年降幅较大,回灌率较低,新近系回灌效果不明显,还存在很多无证开采的现象.针对这些问题,建议相关部门严格控制开采量,时刻关注水位降幅情况,增大回灌力度

| Abstract: | Tianjin is one of cities which rich in geothermal resources and it developed and used the resources in our country in the earlier time.After 1990s,it started to use geothermal resources in heating,bathing,breeding,etc.At present the geothermal heating area is about 12.33 million square meters.Tianjin become the largest city which uses geothermal heating in China,and obtains the "Chinese hot spring city" title.Geothermal resources have become the rare and clean energy in Tianjin economic development and urban environment quality improvement.However,the main geothermal reservoirs have formed depression cones.Minghuazhen Fm.geothermal reservoir formed depression cones in the urban areas and the four new districts;Guantao Fm.geothermal reservoir formed the largest depression cone in Dagang;Wumishan Fm.geothermal reservoir in the urban area formed a large cone of depression.Tianjin geothermal resources development and utilization have a higher degree,however,there are many problems in the process of development and utilization.The main problems are water level has annual large decent,recharge rate is low,and the Neogene recharge effect is not obvious.Further more,there are still many undocumented exploitation phenomenon.To solve these problems,it is recommended that the relevant departments to strictly control the mining,concern about the water level decline and increase the recharge efforts. |
