| 摘 要： | 依靠大量的岩心观察、测井、地震和分析化验资料,对东濮凹陷北部古近系沙三中段沉积体系类型、分布规律和充填模式进行了研究。认为沙三中段主要为湖相背景下各类三角洲前缘沉积,如扇三角洲前缘、辫状三角洲前缘和正常三角洲前缘。在沉积体系研究的基础上,分析研究区北区、中区、南区3个不同区带沉积充填特征,并建立了整个凹陷北部沉积相平面分布模式。 |
| 关 键 词： | 东濮凹陷 沉积体系 充填模式 沉积相模式 |

| Abstract: | The present paper deals,on the basis of core examination,well logs,seismic data and laboratory analysis,with the types,distribution and filling models for the sedimentary systems in the middle part of the third member of the Shahejie Formation in northern Dongpu depression,where the lacustrine delta front deposits predominate,including the fan delta front,braided delta front and normal delta front deposits.The plain deposits are less developed.In addition,the gravity flow,storm and beach-bar deposits occur as well in the study area.Finally the sedimentary facies model is constructed based on the deposition and filling patterns for the northern,central and southern parts of the Dongpu depression. |
| Keywords: | Dongpu depression sedimentary system filling pattern sedimentary facies model |
