| 摘 要： | 利用地震地层学原理,识别出黄骅坳陷古近系沙河街组一段存在上超、削蚀等地震反射现象,结合钻测井资料,综合应用层序地层学原理将黄骅坳陷古近系沙河街组一段划分为3个三级层序,即SEs31、SEs21、SEs11,分别对应于沙一下亚段、沙一中亚段和沙一上亚段,每个三级层序内发育完整的低位体系域(LST)、湖侵体系域(TST)和高位体系域(HST)。各个层序的空间展布受控于坳陷内部的主干断裂,其沉积厚度与沉积范围在局部地区有所不同。

| Abstract: | Based on the principle of seismic stratigraphy,the onlap and truncation seismic reflection in the 1st Member of Palaeogene Shanghejie Formation were identified.Combined with drilling and logging data,the sequence stratigraphic method was used to divide the 1st Member of Palaeogene Shahejie Formation into three third-order sequences such as SEs31,SEs21,SEs11 from bottom to up,which were correspond to the lower,middle and upper 1st Member of Shanghejie Formation.Entire system tract LST,TST and HST were developed in each of the third order sequence.The space distribution of each sequence is controlled by the main fault of the depression,which results in different thickness and scales in local area. |
