摘要： 储集层厚度研究与油气勘探和开发有着直接而紧密的联系。分析储集层厚度在纵、横向上的变化,对于寻找岩性油气藏具有重要意义。提出了基于改进小波的时间域厚度谱储集层成像方法,这是一种单道分析方法,可以生成一地震道的厚度谱,分析纵向上厚度的变化,当沿剖面对不同地震道进行分析时就可以研究厚度沿横向上的变化。试验结果表明,本方法解释直观,分辨率高,具有一定的应用价值。

Abstract: The study of reservoir thickness has direct and close relations with gas-oil prospecting and exploitation.The analysis of vertical and horizontal changes of reservoir thickness is of great significance for finding out lithologic oil-gas pools.This article puts forward a time domain-thickness spectrum method for reservoir imaging based on improved wavelet.The single-trace analysis method can be used to produce a seismic trace spectrum for analyzing vertical changes of reservoir thickness.When we analyze other seismic traces along seismic profiles, the horizontal changes of reservoir thickness can also be studied.Testing results show that this is a visual and high resolution method and has a value for application.

Key words: time, reservoir rock, frequency, thickness, resolution
