测井资料与地震属性关系研究综述

A Review of Study on Relation Between Well Logging Data and Seismic Attributes

测井资料和地震资料是地震勘探中两种最重要的资料 ,由于地震波的频散 ,使合成地震记录与地面地震记录不能完全匹配 ,因此使用之前必须对二者进行频率校正 ;地震资料在测井资料约束下可以进行反演 ,以求取地下波阻抗 ,主要有两种方法 :基于褶积模型的波阻抗反演方法和基于波动方程的波阻抗反演方法 ;可以用多属性变换由地震资料预测测井信息。上述 3种方法是目前研究测井资料与地震属性关系的主要方法。

The well logging data and seismic data are two most important data in the seismic prospecting. There are three important methods to study the relation between the well logging data and seismic attributes. Because the synthetic seismic record and the seismic record data got in the surface are not well matching caused by the dispersion of seismic wave, frequent correction between them must be done before use. Under control of well logging data, there are two important methods to get wave impedance from seismic data inversion: wave impedance inversion method based on convolution model and wave impedance inversion method based on wave equation. Using seismic data attributes can predict the information of logs.
