摘要
近年来的研究表明,在勘探与薄层砂岩体有关的油气藏时,薄层砂体的识别和解释尤为重要,如果掌握了这些变化的特点和规律,反过来就可以更正确地、细致地解释实际薄层地震剖面上各种地质现象。本文通过建立不同模型,在前人研究的基础上讨论了速度对各模型当中薄层振幅和相位特征的影响,总结了速度随薄层振幅和相位特征的变化规律,为实际薄层地震剖面资料处理和解释奠定了基础。
In recent years, studies have shown that it is important for the identification and interpretation of thin sandstone in the exploration of reservoir. If we get hold of the characteristics and laws of these changes, then we can interpret the various geological phenomena in the aetual thin layer seismic section more accurately and detailedly. In this paper, some different models are established, in the foundation of previous studies, the impact of thin layer amplitude and phase characteristics which changed by speed are discussed among models and the law of the change between them is summarized, which provides the foundation for the actual data processing and interpretation of seismic section.
