小波变换去噪地震记录的熵谱分析及应用效果
ENTROPY SPECTRUM ANALYSIS OF SEISMIC RECORD WITH NOISE REDUCTION BY SMALL WAVE TRANSFORM AND ITS APPLYING RESULT
【摘要】 油气检测过程中,去除噪声的干扰,小波变换是一个非常有效的手段。本文介绍了小波变换去噪的原理及其在升平一汪家屯地区的应用效果,并与未做小波去噪的检测结果进行了对比。
【Abstract】 This paper introduces theory of noise reduction by small wave transform and its applying result in Shengping - Wangjiatun area. Comparison is made with the detecting result without noise reduction.
