| 摘 要： | 东营凹陷古近系与新近系之间存在一区域不整合面,该不整合面抬升剥蚀过程的恢复和剥蚀量计算,对恢复区内埋藏史、热史以及生烃史有重要意义。通过对东营凹陷胜坨地区24口钻井测井资料的分析研究,利用米氏旋回地层学方法获得的地层地质年龄、沉积速率作为沉积速率剥蚀量计算方法的参数,计算出了该地区古近-新近系不整合的剥蚀量,所获得的结果与现有的地质认识吻合较好。

| Abstract: | There is a regional unconformity between Palaogene and Neogene in Dongying sag,and its uplift reconstruction and denudation calculation are very meaningful for reconstruction of burial history,thermal history and hydrocarbon generation history in the sag.Based on an analysis of log data from 24 wells in Shengtuo area,Dongying sag,the method of Milankovitch cycle sequence is used to obtain stratigraphic age and sedimentation rate.As two parameters,the stratigraphic age and sedimentation rate are used to calculate denudation amount on the unconformity,and the results are quite consistent with our existed knowledge of the sag. |
