| 摘 要： | 综合钻井、测井和古生物等资料，依据沉积学基本原理和方法，对济阳坳陷沾车地区古近纪东营组沉积相特征及空间展布进行研究。结果表明：沾车地区东营组发育冲积扇相、曲流河相、三角洲相、扇三角洲相、辫状河三角洲相、湖泊相、滩坝和湖底扇8种沉积相，以湖泊相为主。东营组三段盆地持续下陷，深湖相、滨浅湖相发育，沉积范围广。东营组二段湖盆重新开始抬升，湖水收缩，沉积范围缩小，沉积相以滨浅湖相为主，伴有小规模的扇三角洲及滩坝沉积。东营组一段湖盆继续抬升，沉积范围进一步缩小，主要为冲积扇河流沉积，凸起边缘发育一系列的冲积扇。

| Abstract: | Based on core drilling,logging and paleontological data,according to basic principles and methods of sedimentology,sedimentary facies and evolution of Paleogene Dongying formation in Zhanche area has been studied.As showed by the results,8 types of sedimentary facies developed in Dongying formation in Zhanche area,including alluvial fan,meandering rivers,delta,fan delta,braided river delta,lake, beach bar and the bottom of the lake fan,and dominated by lake facies.The third section of Dongying formation has been depressed continuously,deep lake facies and shore shallow lake facies developed well with wide range.The second section of Dongying formation begins to uplift again,lake shrinkage,and deposit square reduced.Sedimentary facies dominated by shallow lacustrine shore facies,accompanied by small scale fan delta and beach bars sedimentary facies.The first section of Dongying formation uplifted continuously,and deposition areas have been furtherly decreased.Alluvial fan fluvial sedimentary facies are its main type,and series of alluvial fans developed in uplifting edges. |
