摘要
声衰减不仅是岩性研究的重要手段,而且也是指示油气的重要标志之一。而衰减的计算则是很棘手的问题,人们发表了很多该方面的研究成果。目前,计算衰减的方法有很多种,如频谱比法、能量法、峰值频率法、波形反演法等。本文对几种常用的计算方法进行了总结,通过实例分析对几种方法进行了比较,并对衰减在深部天然气层识别方面的效果进行了分析。
Attenuation is not only an important method to research lithology,moreover,it s a significant symbol of oil and gas indicating.The attenuation computation is a hard nut to crack.It has published many results of this aspect.Nowadays,there are many ways to calculate attenuation,such as spectra ratio,energy,peak frequency,waveform inverse and so on.This article summarized common methods of attenuation computation,made a comparison between these methods via example analysis,and then analyzed the results of iden...
