【摘要】 断陷盆地研究的最大难题之一是地层对比,海拉尔—塔木察格盆地内各凹陷之间所追踪的地震反射层位不统一的主要原因是缺乏区域地震地层的对比标准,从地震层序的成因出发,划分出构造(TE、TK2、TK1n、TK1t和TJt地震反射层)和沉积(TK1y1、TK1d2和TK1d1地震反射层)两种类型的层序界面,建立了区域构造—地层格架的地震地层的对比标准;在盆地构造格架搭建上,提出了成因地震地层对比法,从根本上解决了构造和沉积层序界面难以把握的难题。更多还原

【Abstract】 One of the difficult problems in rifted basin research is seismic strata comparison,and lack of area comparisoncriterion of seismic strata is the main reason which caused tracked seismic reflection disunion between eachdepressed area in Hailaer-Tamucage Basin.Based on the factors of seismic sequence,two kinds of sequence interfaceare classified in this issue,which including structuring interface(TE,TK2,TK1n,TK1t and TJt reflecting horizon)seismicreflecting horizon(TK1y1,TK1d2 and TK1d1 seismic reflecting layer),and the areal structure-strata framework isestablished according to the comparison criterion of seismic sequence.The genesis comparison method of seismicstrata which is based on structural framework building is raised,which can solve the uncertainty both in structuralsequence interface and sedimentary sequence interface completely.更多还原
