银—额盆地石炭—二叠纪以来的构造演化及其残余地层分布
|
摘要
通过对银—额盆地内现有二维地震资料的精细解释,并结合前人研究成果与认识,将研究区石炭—二叠纪及其之后的构造演化划分为5个阶段:石炭纪—二叠纪裂谷、裂陷构造演化阶段;晚二叠世—三叠纪挤压隆升构造阶段;侏罗纪—白垩纪陆内小型断陷盆地构造演化阶段;晚白垩世末期逆冲推覆构造阶段;古近纪—新近纪盆地分割与局部断陷阶段。在此基础上,通过对研究区石炭—二叠纪残余地层进行精细层位对比追踪,获得了石炭—二叠系的区域分布与埋深,为银—额盆地油气勘探提供借鉴。
Through a fine interpretation of existing 2D seismic data in the Yin-e basin,combined with the results of previous studies and understanding,the structural evolution of the research area is divided into five stages after Carboniferous.They are Carboniferous-Permian rift structural stages,Late Permian-Triassic compression uplift basin structural stages,Jurassic-Cretaceous intra continental small fault basin structural evolution stage,Late Cretaceous thrust nappe structural stages,and Paleogene-Neogene basins segmentation and local fracture phase.By fine horizon correlation and tracking for the residual stratum of the Carboniferous-Permian in the study area,the Carboniferous-Permian regional distribution and depth are obtained and it provids for the further exploration.
