Drilling practice of D03 geothermal exploration well in Xiongan New Area
Abstract:D03 geothermal exploration well is arranged at the axis of Niutuo town uplift in Xiong county, Xiongan New Area. The design depth of the well is 2500m and the completion depth is 2511.10m. The purpose of this project is to find out the geological structure and distribution of carbonate reservoir in Jixian System, obtain geothermal hydrogeological parameters and calculate geothermal resource potential. This paper mainly introduces the drilling construction of D03 geothermal exploration well, carries out the screw motor single point directional top leakage sidetracking operation, solves the problem of directional sidetracking in the lost circulation section, explores the application research of cement cementing in lost circulation section, obtains the cuttings and cores of Yangzhuang Formation, distinguishes the dolomite of Wumishan Formation and Gaoyuzhuang Formation, and achieves the exploration purpose. Through drilling construction, coring, cuttings logging and thin section identification, the geological structure and main lithologic characteristics of well area D03 are basically identified. Through pumping test, hydrogeological parameters are obtained and exploitable resources are evaluated.
