摘要
以层序地层学理论为指导,综合利用测井、录井、地质及地震资料,对徐家围子地区登娄库组进行了层序地层划分和对比。研究区登娄库组为一套完整的超层序,自下至上发育低水位体系域,水进体系域和高水位体系域,超层序内部进一步划分为四个三级层序(SQ1、SQ2、SQ3、SQ4),在层序框架内对沉积体系和生、储、盖组合进行分析,预测了有利勘探区带。
Guided by the sequence stratigraphy theory,we established the sequence stratigraphic framework of the Denglouku formation in Xujiaweizi area depending on the comprehensive utilization of well logging,well drilling,geology and seismic data.We could conclude that the Denglouku formation is a super sequence containing four third order sequence（SQ1,SQ2,SQ3,SQ4） depending on the recognition and division of five sequence boundary.We also analyzed the characteristic of the sequence stratum in third order sequence and have divided thesystem tract inside.We analyse sedimentation system and the characters of source-reservoir-cap combination and at last predict the favorable reservoir area within the sequence stratigraphic framework.
