摘要

井约束地震道反演和多项式拟合技术联合应用提高地震记录分辨率的处理方法的基本思想是充分利用已知的测井、地质、地震资料的信息

在它们的共同约束下

去求取一个具有较高分辨率和较宽频带的近似反射系数序列剖面

并对高分辨率处理后的剖面再进行横向多项式拟合处理

不仅提高了地震记录的分辨率而且也提高了地震记录的信噪比.用该方法对某地区部分实际地震资料进行了处理

取得了明显的效果.

Abstract

The processing method of combining well log constrained seismic trace inversion with polynomial fitting technique was used to improve the resolution factor of seismic records.The purpose was to make full use of the ready information of well log

geological and seismic data to constrain seismic trace inversion so as to obtain an opproximate reflectivity sequence section with higher resolution factor and wider band

and then use lateral polynomial fitting technique to process the section.This method does not only improve the resolution factor of seismic records

but also the signal/noise ratio of the records.This method was used to process some seismic data of a certain area

the result was evident.
