摘要
本文以黄县盆地为例,在详细研究盆地钻井、测井等地质资料的基础上,分析盆地黄县组地层沉积特征,共识别出冲积扇、扇三角洲、近岸水下扇和湖泊等4种沉积相类型,在此基础上,利用高分辨率层序地层学的理论方法,识别基准面旋回界面以及不同级次的基准面旋回,将该盆地划分为1个超长期旋回、2个长期旋回、6个中期旋回,并据此将黄县盆地黄县组划分2个构造演化阶段,每个构造演化阶段发育3个沉积演化阶段。
Taking Huang county basin as an example,based on the detailed study of geological data such as drilling and well logging,the sedimentary characteristics of Huang county Formation in the basin are analyzed.Four types of sedimentary facies,such as alluvial fan,fan delta,inshore underwater fan and lake,were identified.Based on the analysis of high-resolution sequence stratigraphy,the basin is divided into 1 super-long gyration,two long-term gyrations and six medium-term gyrations,and the Huang county formation of Huang county basin is divided into two tectonic evolution stages,each of which develops three sedimentary evolution stages.
