摘要(Abstract)：

为解释高分辨率地层层序,通过Blackman-Tukey频谱分析方法探测地层中存在的周期.对电成像测井数据进行预处理,提炼基质电导率曲线;研究Blackman-Tukey频谱分析识别地层周期的方法,借助古地磁测井和地磁极性时间尺度资料,将地层周期信号从深度域转换到时间域,并与地层年代建立联系.结果表明,用Blackman-Tukey频谱分析方法识别地层周期很好地吻合米兰克维奇周期,证明此方法的准确性,为利用电成像测井数据进行地层周期的识别及高分辨地层层序的划分提供方法和思路.

关键词(KeyWords)：电成像测井;Blackman-Tukey频谱分析;地层周期;古地磁测井;米兰克维奇周期
