摘要
以层序地层理论为指导,通过对埕北地区古近系东营组地层的地质、钻井、测井及地震等资料进行综合分析,识别出7个三级层序界面,将东营组地层划分为1个二级层序,6个三级层序,从下向上依次为:SQ 1(对应于东营组东三段下亚段)、SQ 2(对应于东营组东三段上亚段)、SQ 3(对应于东营组东二段)、SQ 4(对应于东营组东一段下亚段)、SQ 5(对应于东营组东一段上亚段下)、SQ 6(对应于东营组东一段上亚段上),并对各层序界面的识别标志及特征进行了较深入的分析。
Guided by the theory of sequence stratigraphy, by analyzing geologic data, well drilling data, logging data and seismic data of the Paleogcne Dongying Formation of Chengbei region, the paper recognites 7 three-grade sequence interfaces, and divides strata of Dongying Formation into 6 three-grade sequences. They are SQ1 （corresponding to lower Ed3）, SQ2（corresponding to upper Ed3）, SQ3 （corresponding to Ed2）, SQ4（corresponding to lower Edx）, SQ5 （corresponding to lower- stage of upper Ed1）, SQ6（corresponding to upper-stage of upper Ed1） from the mountain foot going upwards. And the paper analyzes recognition marks and characteristics of every sequence interface in a deep going way.
