地震Wheeler转换技术及其应用
|
摘要
如何有效利用地震资料进行层序和沉积期次的划分以及内部层序的自动追踪,一直是层序地层学研究所面临的技术难题。地震Wheeler转换技术是最近几年发展起来的一项新技术,它将层序地层学和地震沉积学更好地结合起来,从而可以最大限度地应用三维高精度地震资料进行地层层序和沉积期次的研究。首先系统阐述了地震Wheeler转换技术的基本原理和实现方法,然后采用三角洲沉积体地质模型验证了方法效果,最后将该方法用于东营凹陷三角洲层序的划分,结合测井资料以及时频分析方法,重新厘定了层序划分方案,将东营凹陷三角洲沙三段中亚段划分为9个四级层序。
How to effectively applying seismic data for dividing sequences & sedimentary cycles and tracing inner sequences is always a technical problem in sequence stratigraphy.The seismic Wheeler transform technology is a new method developed in recent years,which combines sequence stratigraphy and seismic sedimentology together better.Therefore,by using this method,we can study stratigraphic sequences and sedimentary phases with 3-D high accuracy seismic data to maximum.Firstly,the basic principle and implementation of the seismic Wheeler transform technique was explained systematically.Secondly,the validity of the method was verified by using delta front sedimentary geological model.Finally,this method was used in the division of cycles and stages of delta in Dongying Depression,combined with logging data and time-frequency analysis method,the sequence classification scheme was redefined.As a result,middle Es3 of Dongying Delta was divided into nine fourth-level sequences.
