| Abstract:Well D21 was drilled to explore the geothermal resources in the western slope zone of Rongcheng. The China Geological Survey deployed Well D21 in Rongcheng， Xiong’an New Area with the designed depth of 3000m， and the completion depth 3083.74m. This article introduces the drilling conditions， well structure， drilling operation， and pumping test process of Well D21， and summarizes the drilling results obtained. The hydrogeological parameters of the thermal reservoirs in the Cambrian and Jixian systems have been collected from the well， and they can be used for planning of geothermal development in the new area. |
