时频分析精细划分欢喜岭地区地层层序
|
摘要
高精度层序地层学研究的关键是各级层序界面的识别与确定。时频分析技术与传统的层序划分方法相比,具有一定的优越性,该技术可以将微小沉积旋回体的时频差异显示出来,减小人为因素的影响,为高精度层序地层的定量划分提供依据。文中以辽河西部凹陷欢喜岭-鸳鸯沟地区高精度层序地层格架建立为例,综合运用研究区地震和测井资料,借助测井连续小波变换和地震时频分析技术来确定具有等时意义的层序界面。应用结果表明,利用测井连续小波变换和地震时频分析技术进行层序旋回划分是较为可靠和实用的,辽河凹陷欢喜岭-鸳鸯沟地区沙河街组共发育5个具有等时意义的层序界面,可以将其划分为6个三级层序。
The key of high-resolution sequence stratigraphy study is the identifying and ascertaining of each sequence boundary.Compared with the methods of conventional sequence dividing,time-frequency analysis technology exhibits the superiority in showing the time-frequency difference of small sedimentary cycles,which decreases the influence of human factor and provides the reference for the quantitative division of high-resolution sequence stratigraphy.Taking high-resolution sequence stratigraphy framework,established in Huanxiling-Yuanyanggou Area in the western depression of Liaohe,as an example,this paper confirms the isochronic sequence boundaries by the seismic time-frequency analysis method and logging continuous wavelet transform technique in terms of seismic and well logging data.The research result shows that it is reliable and practical to divide the sequence and cyclic through the utilizing of the method and technique.Five isochronic sequence boundaries have been developed in Shahejie Formation of Huanxiling-Yuanyanggou Area,which can be divided into six third-order sequences.
