惠勒域转换技术是通过对地震同相轴的拉平和重排,将地震数据体由时间域转换到惠勒域,进而开展沉积特征研究。在东营三角洲沉积体系地震沉积学研究中,运用该技术自动追踪出沙三段中亚段目的层段内所有的层序界面,并在惠勒域中实现了三角洲期次的划分及对沉积韵律体空间展布特征的分析。通过与时间域的同步解释,自动识别出主要的沉积等时面。在此基础上,运用地层切片属性分析技术,突出了沉积特征在等时界面上的地震映像,进一步明确了三角洲体系的平面展布特征。
Wheeler domain transformation technology is through the leveling and rearrangement of seismic events, the seismic data from the time domain to the Wheeler domain, and then carry out sedimentary features. In the study of seismic sedimentology in the sedimentary system of Dongying delta, this technique is used to automatically track all the sequence boundaries of the Meso-Eogene Member Segment in the third member of the Eocene, and to achieve delimitation of the delta period in the Wheeler domain, Analysis of Body Spatial Distribution Characteristics. By synchronizing with the time domain interpretation, the main sedimentary isochronous surface is automatically identified. On this basis, using the stratal slice attribute analysis technique, the seismograms of sedimentary features at the isochronous interface are highlighted, and the plane distribution characteristics of the delta system are further clarified.
