This article samples the hot research topics in geothermal exploitation in 2018. With the rapid development of geothermal power generation in countries all over the world, China is facing great opportunities and challenges. Geothermal exploration is gradually refined, geothermal development is gradually intensified, and geothermal utilization is gradually integrated. Meanwhile, geothermy has become a real hot spot in geological field and relevant technologies and norms are constantly improved, for example, closed underground heat transfer technology, geothermal evaluation technology of balance in exploitation and reinjection, geothermal-solar energy and other mixed energy development and utilization. In theories, the mechanism between geothermal water exploitation and the occurrence of microseisms is further understood, and the theory of hot dry rock development becomes more thorough. In addition, innovative ideas in ecological environment and earth science around geothermal fluid are also presented.
