| Abstract:In order to explore the geothermal resources in the Rongcheng geothermal field， the Geological Survey of China has deployed a geothermal exploration well D15 in Xiong’an New Area with the design depth of 3000m and the completion depth 3111.58m. It is intended to reveal the development of the strata in the northern slope zone of the Rongcheng uplift and serve the geothermal development planning of Xiong’an New Area. This paper describes the drilling achievements， including completion of the drilling tasks， assurance of drilling quality； and summarizes hydrothermal well drilling fluid technology， selection of the coring tools， and acquisition of the physical data such as core， cuttings and other. Perforation operation was performed for pumping test to obtain formation parameters on water temperature and volume so as to provide data for the investigation and evaluation of geothermal resources in Xiong’an New Area. |
