摘要
准噶尔盆地西缘车排子地区具有类前陆盆地前隆—隆后斜坡带的层序格架特征,其层序形成和体系域变化主要受控于准噶尔盆地南缘向西和向北的幕式逆冲和松弛作用,具二元体系域结构的层序地层格架特征。对石炭系以上地层的层序进行了深入研究,识别出5个等时层序界面,划分了3个二级层序组和4个三级层序。在此基础上,对层序内部体系域构成、沉积体系特征及时空配置规律等进行分析,并建立了砂体预测模型,确定了有利储集相带。
The Chepaizi area in western margin of Junggar basin is characterized by the binary-system-tracts sequence framework of fore-uplifted-back-uplifted slope belt of sub-foreland basin.Its sequence formation and systems tract variation are mainly controlled by the episodic thrusting activity and relaxation effect,one is from east to west,and the other is from south to north in the southern margin of Junggar basin.This paper presents in-depth researches of sequences of the Carboniferous and the above strata,including the identification of five isochronous sequence interfaces and the classification of three second-order sequence groups and four third-order sequence groups,based on which,analyzes the system tracts structures,the depositional system characteristics and the space-time configuration in the sequences.Finally,this paper develops sand-body prediction model and determines the favorable facies belts in this area.
