摘要: 黄骅坳陷孔南地区孔三段是渤海湾裂陷盆地古近纪最早的沉积地层。通过对地震、测井、岩性资料的综合分析,识别出孔三段的层序界面。采用P.R.Vail的经典层序地层学陆相湖盆三分法则,划分出了孔三段内部各体系域。

Abstract: The third member of the Palaeogene Kongdian Formation in southern Kongdian, Huanghua depression is believed to be the earliest sedimentary strata in the Bohai Bay rifted basin. The identification of sequence boundary is based on the lithologic characteristics, well logs and seismic data. The division of the depositional systems tracts is made for the third member of the Palaeogene Kongdian Formation by using the tripartition rule of continental lake basin from Vail's classic sequence stratigraphy.
