| 摘 要： | 利用钻井、测井、露头和地震等资料采用沉积学、层序地层学、地震地质学等方法，研究济阳坳陷馆陶组沉积特征，并进行了层序地层划分，结果发现：济阳坳陷馆陶组地层主要发育河流相沉积，馆陶组下段存在以浅水湖泊为背景的辫状河三角洲沉积，馆陶组上段发育湖泊三角洲沉积以及曲流河浅水三角洲沉积，在此基础上，进行了层序界面识别与层序划分，可将馆陶组地层可划分出一个构造层序，2个三级层序，层序底界面都为I型层序界面，每个层序内又可划分出3个体系域，即低水位体系域、扩张体系域和高水位体系域。

| Abstract: | By using drilling,logging,and seismic data,sedimentology,sequence stratigraphy methods, earthquake geology,sedimentary characteristics of Guantao formation in Jiyang depression have been stud-ied,and the sequence stratigraphy has been divided.It is found that：Guantao formation in Jiyang Depres-sion mainly developed fluvial facies sediments,braided river delta sediments with shallow lakes as the background existed in the lower section of Guantao formation,and lake delta sediments and shallow mean-dering river delta sediments developed in the upper section of Guantao foramtion.On these basis,sequence interface identification and sequence stratigraphy division have been carried out.Guantao formation can be divided into a tectonic sequence and two third-order sequences.Sequence end interfaces are type Ⅰ se-quence boundary.Each sequence can be divided into three systems,that is low water level system,expan-sion system,and domain and HST. |
