摘要
雄安新区地热资源丰富且比较容易开采,在生态文明建设中可发挥重要作用。雄安新区浅层(<200米)地热能宜于开采;深层(200—3000米)地热能中的砂岩储层和碳酸盐岩储层热量大,宜于开采;超深层(>3000米)地热能也具有开采潜力。雄安新区的雄县在利用大型岩溶热储开展规模化供暖方面,单一项目已实现世界最大(450万平方米)供暖能力。文章认为,雄安新区应该加大地热资源勘查力度,重点是超深层碳酸盐岩热储;在利用上,要做到因地制宜,深、浅资源合理配置,还要重视环境保护,协调好与其他资源利用的关系;同时,要发展地热储能技术,形成以地热为主体,多能互补的"地热+"的清洁能源利用新格局。
Xiongan New Area is rich in geothermal resources, which may play a key role in the construction of ecological civilization. The shallow geothermal energy （〈200 m）, and deep geothermal energy stored in sandstone and karstic reservoirs are rich and suitable for exploition and utilization. The deep carbonate geothermal resources is particularly large and easy to be exploited. Geothermal resource stored in super deep layer （ 〉3000 m ） is also of good potential. The Xiongxian City located in the Xiongan New Area, has pioneered in the large-scale district heating using karstic geothermal resources, which is the largest single project in the world that has a total geothermal heating capacity of 4.5x 106 me. The author believes that the exploration of geothermal resources in the future should be enhanced, especially in super-deep geothermal resource exploration. On the use of geothermal energy, we should make full use of the shallow geothermal energy, adjust measures to local conditions, and make rational allocation of shallow and deep geothermal resources. In addition, we should also pay attention to environmental protection, and coordinate the relationship between geothermal resources and other energy. At the same time, we should widely apply the technique taking advantage of storage function of geothermal reservoirs, and gradually construct the new development pattern of clean energy that geothermal energy is used as main body and others are complementary energy.
