| Abstract:D03 geothermal exploration well is deployed at the axis of Niutuo Town Uplift in Xiong County, Xiongan New Area with the design depth of 2500m and the completion depth 2511.10m. The purpose of this project is to find out the geological structure and distribution of carbonate reservoir in the Jixian System, obtain geothermal hydrogeological parameters and calculate geothermal resource potential. This paper mainly introduces the drilling work of D03 geothermal exploration well, where sidetracking was carried out against lost circulation with the PDM single point orientation, the difficulty in sidetracking in the lost circulation section was resolved, and the application research for cementation in the lost circulation section was explored, the cuttings and cores from Yangzhuang Formation were obtained with the dolomite of Wumishan Formation distinguished from Gaoyuzhuang Formation, achieving the exploration purpose. Through drilling work, coring, cuttings logging and thin section identification, the geological structure and main lithologic characteristics at D03 were basically identified. Through pumping test, hydrogeological parameters are obtained and exploitable resources were evaluated. |
