鄂尔多斯盆地地震层序划分及有关问题探讨

APPROACHES TO SEISMIC SEQUENCE DIVISION IN THE ORDOS BASIN AND RELATED PROBLEMS

地质矿产部石油物探研究所

根据地震反射波终止特征,将鄂尔多斯盆地中、古生界划分为五个地震层序或两个超层序。同时详细地介绍了各地震层序的特征,并就地震层序的划分和有关地质问题进行了探讨。

Based on the seismic reflection arrivals and termination characters, Mesozoic and Palaeozoic groups in the Ordos Basin are divided into 5 seismic sequences or 2 ultrasequences. Moreover,the characteristics of each seismic sequence are presented in considerable detail. Approaches are made with respect to the division of seismic sequence and problems pertinent to geology.
