| 摘 要： | 以大量的地质、地球物理资料及前人研究成果为基础，运用沉积学原理和方法，详细地分析了辽东湾盆地东营组二段的沉积相特征。经分析认为，东营组二段虽整体为湖泊-三角洲沉积体系，但其下部与上部的沉积特征差异明显：下部以湖相环境为主，上部则主要为三角洲沉积。在综合了该区构造特征和水系发育特征后，编制了东二段下和东二段上的沉积相平面展布图，并指出，辽西低凸起北倾末端和辽中凹陷中南洼为最有利的勘探区带。

| Abstract: | Based on the geology,geophysics and predecessors studies and applying sedimentary principles and methods,this article makes a detailed analysis of the feature of sedimentary faces in Liaodong Bay's second member of Paleogene Dongying Formation.It is indicated that although the whole second member of Dongying Formation is lake-deltaic depositional system,the difference of the upper and lower parts of second member of Dongying Formation is obvious.The lower part mainly included lake system,while the upper par... |
