摘　　要：为明晰义东断裂带砂砾岩体的期次划分及相带展布特征,综合分析岩相、测井、地震等资料,在已钻井区带,利用小波变换技术建立义东断裂带沙河街组的高分辨率层序格架,由时频分析技术将其拓展到未钻井区,从而落实义东断裂带砂砾岩体的期次,是比较可行的办法。TThe feasible method to understand the stage division and facies belt distribution characteristics of glutenite body in Yidong fault zone is that the high resolution sequence framework of the Es in the Yidong fault zone by the wavelet transform in the drilled well area combined with the lithofacies, log information, seismic data and so on, and the sequence framework are extended to the undrilled area by the time-frequency analysis.

关 键 词：砂砾岩体 期次划分 沉积相特征 义东断裂带
