摘要

高分辨率地震勘探是一项系统工程。在伊克昭盟地区高分辨率地震勘探中应用频谱整形高频提升补偿及高采样等保护高频信号;处理方面应用叠前高精度静校正技术、去噪技术、叠后子波处理技术等

使剖面信噪比提高

主频增高

频谱增宽。高分辨率地震勘探应用效果明显

主要表现为:(1)分辨薄层能力提高;(2)剖面显示能力增强;(3)使构造解释更加准确。

Abstract

High resolution technique in seismic exploration is a systematic engineering.In high resolution seismic exploration made in Ih Ju League

spectrum shaping

high frequency promotion and compesation

high sample rate methods were adopted to preserve high frequency signals; in seismic processing

pre-stack precise static correction

noise eliminating and poststack wavelet processing were used to improve signal/noise ratio

heighten master frequency and widen spectra.This technique has been proved to be effective especially in: 1.improving lamina resolution acuity; 2.increasing profile displaying ability; 3.improving the accuracy of structure interpretation.
