| 中文摘要: |
| 大连地区地热条件优越，地热资源较为丰富，地下可开采热水总量为 5. 86×106 m3/a，地热资源总量 1. 89× 1016 J，折合标准煤 1. 28×105 t/a。地热类型可分为断裂对流型和传导型，热源主要来自断裂沟通深部岩浆热和沿断裂破碎带产生的摩擦热，热储层以断层破碎带为主，水源主要为大气降水，成因模式为深循环，循环介质为中生代花岗岩和元古代石英岩、板岩。本文基于地热资源的禀赋条件、水化学特征、控热和导热构造、热储层和盖层特征研究的基础上，开展了地热成因和资源潜力分析，结合对地热资源开发利用现状的研究，提出了城市清洁能源可持续开发利用建议。 |
| 英文摘要: |
| The geothermal condition is excellent and geothermal resource is rich in Dalian area，the total amount of geothermal exploitable hot water is 5. 86×106 m3/a，the total amount of heat energy is 1. 89×1016 J， equivalent to standard coal 1. 28×105 t/a. Geothermal type can be divided into fracture convection type and conduc. tion type，the heat sources is mainly derived from the magmatic heat and the friction heat generated along thefracture zone，the thermal reservoir is Mesozoic granite or Proterozoic quartzite and slate，the water sources is mainly atmospheric precipitation，and the genetic model is deep circulation. Study on the occurrence conditions of geothermal resources，hydrochemical condition，thermal control structure and thermal conduction structure， characteristics of the thermal reservoir and caprock，analysis of geothermal origin and resource potential，combine with the study on the present situation of geothermal exploitation and utilization，put forward countermeasures about sustainable exploitation and utilization of urban clean energy. |
