Analysis of high-quality drilling construction technology for geothermal wells under the new situation

Abstract:

Geothermal drilling construction is a rigorous work with high professional requirements， and the matched equipment and process tools are the guarantee for the smooth progress of construction. It is critical to improve the professional quality of the team and the technical capacity of the unit， as well as adopting advanced technology under the new situation. In addition， China''s geothermal market is expanding toward the deep strata， which brings increasing construction difficulties. Construction enterprises with proprietary construction technologies and characteristics can maintain development momentum and gain competitive advantages in the market. This paper analyzes some specific problems in geothermal well construction， and points out that multi-process air drilling is an effective method for high-quality and efficient exploitation of deep geothermal and groundwater resources.
