| 摘 要： | 以层序地层学理论为依据,综合运用地震、钻井、测井、野外露头和古生物资料,在井—震联合标定的基础上,对准噶尔盆地西北缘车排子地区下白垩统层序地层及沉积演化进行研究.结果表明:下白垩统可划分为2个三级层序；下部层序KSI结构发育完整,低位体系域以辫状河和扇三角洲沉积为主,下切谷特征明显,水进体系域发育滨浅湖沉积,高位体系域发育扇三角洲、滨浅湖沉积；上部层序KSII低位体系域不发育,水进体系域主要发育滨浅湖沉积,高位体系域在湖平面缓慢下降、陆源碎屑物质供给不断减少的环境下发育曲流河、扇三角洲、滨浅湖沉积；下白垩统沉积建造反映研究区的沉积演化具有一定旋回性,早白垩世古气候变化对层序的发育起重要的控制作用.

| Abstract: | Based on the theory of sequence stratigraphy,the sequence stratigraphy and sedimentary evolution of Lower Cretaceous series in Chepaizi area,northweastern margin of Junggar Basin were studied by comprehensive application of seismic data,drilling data,logging,outcrop data,paleontological data and well-seismic calibration. The results show that the Lower Cretaceous can be divided into two third-order sequences.The lower part of sequence KSI develops well.The lowstand system tract(LST) is dominated by braided ... |
