天津市滨海地区包括塘沽、大港、汉沽三个地区。区内蕴藏着丰富的地热资源,新生界第三系明化镇组和馆陶组是本区的主要地热储集层,其中明化镇组热储层温度为35℃~50℃,馆陶组热储层温度45℃~70℃。目前滨海地区地热资源的主要利用方式包括:地热采暖、温泉洗浴、矿泉水开发、水产养殖等方面。尚存在利用程度低,单井利用方式单一等问题。合理开发、梯级综合利用已经越来越引起重视。该文通过对滨海地区地热地质条件的阐述,对该区地热资源的利用方式和利用前景进行了充分的分析,并对地热开发利用过程中的主要环境问题进行了分析,展望了天津市滨海地区地热开发利用前景。
Tianjin Binhai area includes Tanggu, Dagang, Hangu three areas. There are abundant geothermal resources in the area. The Minghuazhen and Guantao formations of the Tertiary in the Cenozoic are the main geothermal reservoirs in this area, of which the temperature of the Minghuazhen Formation thermal reservoir is between 35 ℃ and 50 ℃, Group thermal reservoir temperature 45 ℃ ~ 70 ℃. At present, the main utilization methods of geothermal resources in the coastal area include: geothermal heating, hot spring bathing, mineral water development and aquaculture. There are still some problems such as the low degree of utilization and single well utilization. Rational development, cascade utilization has drawn more and more attention. Based on the elaboration of the geothermal conditions in the coastal area, this paper fully analyzes the utilization patterns and utilization prospects of the geothermal resources in this area, and analyzes the major environmental problems in the process of geothermal development and utilization. The paper forecasts the coastal areas in Tianjin Geothermal development and utilization prospects.
