| Geothermal energy is the heat from the deep Earth. It is a clean, low-carbon and green and renewable recourse. Efficient development of geothermal resources is of great importance for adjusting our country’s energy structure. Currently, the drilling technology for high-temperature (HT) geothermal wells is essentially based on traditional drilling equipment for oil and gas exploration. Due to the special nature of the HT geothermal reservoirs, the efficiency of conventional drilling technologies is low and the cost is relatively high. To meet engineering requirement of HT geothermal resources, this article introduces the types of HT geothermal reservoirs, analyzes reservoir characteristics and key drilling technologies for efficient development including lost circulation control technologies, efficient rock breaking, HT downhole tools and equipments, HT drilling fluids, HT cement technologies and advanced drilling technologies. At last, this paper gives some suggestions about tackling key problems in drilling technology for efficient development of HT geothermal resources in the future. |
