Linnan sub - depression which is mesozoic and cenozoic faulted lacustrine basin is located in the southwestern part of huimin sag, depression of jiyang. it is dominated by lacustrine - fill sub - depression. based on well logs, three - dimension seismic profiles, cores and other basic data, 10 horizons including 6 turnaround surfaces and 4 maximum flooding surfaces are defined from es3 to the lower part of es2 formation, and 1 long - term and 5 intermediate - term base - level cycles which are named from c5 to c1 could be identified, and then the chronostratigraphic framework of the sub - depression is built
本文以巖心、鉆井、測井、地震資料為基礎，在下第三系沙三段沙二下的一個長期基準面旋迴（二級層序）內部識別出10個有時間地層對比意義的界面，包括6個基準面下降到上升的轉換面（層序界面） ， 4個基準面上升到下降的轉換面（湖泛面） ，劃分出c1 - c5五個中期基準面旋迴，建立了等時地層格架地層格架。 -
Based on well logs, three - dimension seismic profiles, cores and other basic data, author recognized the sequence horizons of high - scale by the changes of a / s ratio, and established high - resolution chronostratigraphic framework using multi - term base - level cycles of high - resolution sequence stratigraphy, combining sequence theory with sedimentology. the depositional system characters and distribution were outlined and the prospective areas for stratigraphic traps were defined : jishan and jiangjiadian
本文是以鉆井、地震資料、巖心和各種分析化驗資料為基礎，以多級次基準面旋迴為參照面的高解析度層序地層學理論與研究方法將層序地層分析技術與沉積學原理緊密結合起來，運用a / s比值的變化趨勢可以識別高級次層序界面，建立高解析度層序地層對比格架。
