| 摘 要： | 依据层序地层学原理，研究了陆相断陷湖盆自身沉积发育特点，应用沉积学、有机地球化学、石油地质学等理论，综合分析研究了济阳坳陷东营凹陷下第三系密集段的特征．在东营凹陷中，识别出的４种密集段内部结构，反映了不同的物源供应和水动力条件．密集段在岩性、电性、古生物及地球化学特征上均与其上下地层有很大差异．由于密集段的特殊性，它对地层对比、生油岩评价和层序解释均有重要的意义

| Abstract: | According to the principle of sequence stratigraphy and taking the special characteristics of sedimentary evolution of lacustrine basin into consideration, the properties of condensed section of early Tertiary in Dongying sag of Jiyang depression were analyzed by means of sedimentology, organic chemistry and petroleum geology. Four types of internal textures of condensed section were identified in Dongying sag. The different types can reflect the different sedimentary supplies and hydrodynamic conditions. Lacustrine condensed sections are clearly distinguished on lithology, electric behavior, paleontological and geochemistry mark from the overlying and underlying strata. With the special characters, condensed sections have an important significance in stratigraphic correlation, hydric resource evaluation and sequence interpretation. |
