大庆长垣地区登娄库组层序地层特征与有利区预测

应用层序地层学的理论和方法为指导,并结合陆相湖盆层序地层学的特征,利用测井、岩心等资料,依据界面反射特征将大庆长垣地区登娄库组划分为四个三级层序( Sql、Sq2、Sq3、Sq4),进而建立起地层格架.对大庆长垣地区登娄库组沉积体系进行分析,共识别出河流、扇三角洲、湖泊、辫状河三角洲四个沉积相,综合分析各层序沉积特征及生储盖组合,预测了有利区带.

Sequence Stratigraphy and Prediction for Prospective Targets of Denglouku Group in Daqing Placanticline Area

Using the theories and methods of sequence stratigraphy as guide,combined with the continental sequence stratigraphy of basin characteristics,using logging data and core,etc,based on reflection characteristic of the interface region of Daqing placanticline Denglouku group devided into four third-order:(Sq1,Sq2,Sq3,Sq4),and then establish a stratigraphic framework.Region of Cologne Denglouku depositional system analysis,are identified rivers,fan deltas,lakes,four braided delta depositional system,a comprehensive analysis of each sequence and the characters of source-reservoir-cap and at last predict the favorable reservoir.
