【摘要】 运用层序地层学原理识别和对比不整合面、整合面、初始湖泛面、最大湖泛面等各级湖泛面,将层序划分为体系域、准层序组、准层序类型.通过对层序边界形成机理、识别方法、边界类型及特征等方面的研究,结合层序内部结构特征,在地震剖面上,以T23为界可将贝西斜坡南屯组地层划分为2个三级层序,自下而上命名为三级层序Ⅰ和三级层序Ⅱ;建立了研究区地层的等时地层格架,深化了该区开展勘探开发的地质认识.更多还原

【Abstract】 Using the sequence stratigraphy to recognize and contrast unconformity surface, the conformity surface, first flooding surface and maximum flooding surface, starting from the sequence division, and subdividing the system tracts, parasequence sets and parasequence patterns, we established, through studying form mechanisms, isochronal stratum framework of the research area stratum. This work can point out the direction of oil and gas exploration in this area.更多还原
