多项式拟合技术在煤田地震勘探中的应用

APPLICATION OF POLYNOMIAL FITTING TECHNIQUE ON COAL SEISMIC SURVEYING

本文讨论了三种多项式拟合方法在煤田地震勘探中的应用情况 .它们可以消除动校拉伸对波形的影响以及普通叠加的低通滤波效应 ,保持了振幅的真实形态和较高的频率信息 ,能得到较高分辨率的零炮检距剖面 ,有利于地震资料的构造解释和岩性研究 .

In this paper,application of three polynomial fitting methods,which can eliminate the stretching of NMO correction and low pass effect of stacking,and keep true amplitude and higher frequency of seismic data,is discussed im coal seismic surveying. Zero offset profile with higher resolution can be oltainde by polynomial fitting methods, which is helpful to structural interpretation and lithologic research of seismic data.
