摘要
二连盆地都日木凹陷具有较好的油气勘探潜力,结合都参1井钻探、地震数据,系统分析了地层及沉积特征.腾二段、腾一段和阿尔善组为主要的目的层段.在地震剖面上,T3、T6、T8、T11反射层分别对应赛汉组、腾二段、腾一段、阿尔善组底界,并进一步明确了钻井地震分层.结合岩心、单井沉积相、地震相及地层对比结果,划分了主要目的层沉积相.
Abstract
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.
