Research on the Exploration and Development of Geothermal Resources in the New Era

Abstract:

The development and utilization of clean geothermal energy can not only achieve energy saving & emission reduction and optimize energy resource structure, but also drive related equipments manufacturing, urban clean heating, hot spring town building, characteristic ecological agriculture, physical therapy and leisure vacation, tourism and other related industries. With the issuance of “The development and utilization of geothermal energy ‘13th Five-year’ Plan” as well as the practical needs of controlling air pollution, there will be a rapid development period of geothermal resources development and utilization. Therefore, sustainable, scientific and reasonable planning utilization of energy will be a new topic. This paper studies the related issues in geothermal resources management, development and utilization, engineering and hot springs cultural construction. It is suggested by strengthening policy guidance and supervision, carrying out unified management and paying attention to publicity and science popularization to enhance the service ability and role of geological work in the new era. In terms of technology, the technology research should be strengthened on deep well heat exchange system, air drilling and pump suction reverse circulation drilling technologies should be preferred under the permissible geological conditions, development of new type tubing with high strength, corrosion resistance and good thermal conductivity should be carried out.
