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 the identification and interpretation of thin sand bodies are particularly important in the exploration of reservoirs related to thin sandstone bodies. If the characteristics and laws of these changes are mastered, they can in turn be more accurately and meticulously Explain the various geological phenomena on the actual thin-layer seismic section. Based on the previous studies, this paper discusses the influence of velocity on the amplitude and phase characteristics of thin films in different models, and summarizes the variation of velocities with the amplitude and phase characteristics of thin layers. Based on the data of actual thin-layer seismic sections Processing and interpretation laid the foundation.
