莺山地区登娄库组层序地层与油气勘探意义
|
摘要
应用层序地层学的理论和方法,针对研究区的地质概况,综合分析地震、测井、岩心等资料,对莺山地区的层序界面进行识别,共识别出5个三级层序界面(SB1-SB5)。研究区的登娄库组是一套完整的超层序,共发育三个体系域,自下而上为低水位体系域、水进体系域、高水位体系域。在层序格架内,总体以冲击扇、扇三角洲、辫状河三角洲、泛滥平原等相配的沉积体系为主。研究区由下而上共发育3套生储盖组合,表明该区具有一定勘探潜力。
Applying the theories and methods of high resolution sequence stratigraphy,we analyzed seismic,logging and drilling core data of the Denlouku Formation in the Yingshan area of the Songliao Basin in order to understand its sequence stratigraphy.We identified third order sequence boundaries and maximum flooding surfaces and established the sequence stratigraphic framework of the Denlouku Formation.It can be divided into three systems tracts,which include LST,TST,and HST.Eventually established the isochronous stratigraphic framework,for the further development of the basis for exploration and development.In the sequence stratigraphic framework,the overall impact of fan,fan delta,braid river delta,flood plains.The main sedimentary systems.Three source rock-reservoir-cap rock assemblages in Yingshan Area were developed.Show that the area has a certain exploration potential.
