Comprehensive Evaluation of Well DC-1 in the Dukedomu Depression,Eerduosi Basin
The Dukedomu Depression in the Eerduosi Basin exhibits considerable potential for oil and gas exploration.Through the analysis of drilling data from Well DC-1 and the integration of seismic data,a systematic investigation of the stratigraphy and sedimentary characteristics was conducted.The study indi-cates that the Tengge Ⅱ,Tengge Ⅰ,and Alashan formations are the primary target intervals.On seismic profiles,the T3,T6,T8,and T11 reflection layers correspond to the base boundaries of the Saihan,Tengge Ⅱ,Tengge Ⅰ,and Alashan formations,providing further clarity on the well-seismic stratification.By combining core data,single well sedimentary facies,seismic facies,and stratigraphic correlation re-sults,the main target intervals'sedimentary facies were delineated.
