地震资料解释中的速度谱特征分析

THE CHARACTERISTIC ANALYSIS OF STACK VELOCITY SPECTRUM IN SEISMIC INTERPRETATION

本文主要介绍了速度谱特征分析在地震资料解释中的应用，尤其是在含油气储层预测方面的应用。叠加速度谱不仅可以提供速度信息．而且能量团的聚集、发散特征也可以提供油气、构造方面的信息，其接合地震剖面的解释可以提供更多的地质信息。最后，本文以吐哈盆地为例，用速度谱特征分析方法对三个不同构造背景的油田进行含油气储层预测，其结果与油田的实际资料是相吻合的。

The characteristic analysis of stack velocity spectrum applied to seismic interpretation, especially to predicting oil and gas deposits is introduced in this paper. Stack velocity spectrum supply not only information of velocity but also information of oil and gas, as well as structure acording to concentrate, dirergence of stack velocity spetrum energy, which is combined with seismic profile interpretation for suppling more information of gelogy. Finally, this method is applied to three different structure oilfield of Tuba Basin for predicting oil and gas deposits, the results of predicting oil and gas deposits fit in practical data of the oilfield.
