| 中文摘要: |
| 川西地区地热资源丰富,为隆起山地对流型中高温地热资源。热储层属带状热储,岩性主要为断层构造岩,热源主要来自现代活动性大断裂沟通深部幔源岩浆热及沿断裂破碎带产生的机械摩擦热,水源主要为大气降水,成因模式为深循环。基于野外调查、取样分析及区域地质资料分析,区内水热类型齐全,分布严格受控于区内构造且与人口分布具有良好重叠性,流体水化学类型以HCO3-Na型为主,多富含氟与硅且浓度多达理疗热矿水命名浓度,理疗价值高。依据地热流体与热储温度区划、流体水化学特征区划及区域资源等综合因素,将区内地热资源具体区划为3种类型,以供暖、发电为主的6个优先开发区,以休闲旅游、康体保健为主的10个重点开发区及按需利用为主的暂缓开发区。针对地热资源在开发利用过程中可能产生的环境地质问题,提出针对性预防措施,实现地热资源可持续开发利用。 |
| 英文摘要: |
| There is plentiful geothermal resources in western Sichuan region,The moderate-high temperature geothermal resources belongs to the convection type of uplift mountain.Heat reservoir is stratified reservoir, the mainly lithology is fault tectonite, heat source mainly comes from magma thermal which is from the modern active faults connected deep mantle or comes from mechanical friction heat which is produced by fault fracture zone, water supply is mainly from atmospheric precipitation, deep circulation is the main genetic model. Based on field survey,sampling analysis and regional geological data analysis, Hydrothermal types are complete all in readiness, It’s distribution strictly controlled by zone structure and have good space-overlap with population distribution.The hydrochemical types of geothermal fluid are primarily HCO3-Na,The fluid is rich in fluorine and silicon whose concentration can reach the physical therapy named concentration of hot mineral water, possessing high physical therapy value. According to the partition of geothermal fluid, geothermal resources temperature and fluid chemical characteristics,regional resources and so on, geothermal resources can be divided into three specific types, six priority development zone are mainly for heating and generate electricity,ten key development zone are mainly for leisure tourism and medical treatment. According to the need, the rest of the geothermal resources zones which are defined as moratorium development zone can be used.In allusion to possible environmental geologyl problems in the process of the development and utilization of geothermal resources, putting forward targeted preventive measures, realizing sustainable development and utilization of geothermal resources. |
