摘要
介绍了沉积层速度-深度线性模型的原理及其基本特点,利用沿南海海盆深水区一条多道地震剖面解释的速度谱资料,将沉积层速度-深度线性模型应用于该剖面解释数据的时深转换中,建立了与之相关的一整套工作流程,整个流程实现了可视化,并考虑了沉积地层速度的横向变化,为地震剖面的地质解释提供了直观且更为可靠的素材。最后,分别从理论和实践角度分析探讨了该时深转换模型的应用前景和局限性,借此为后续研究工作提供参考。
The theory and basic features of velocity-depth linear model are introduced in this paper. With the velocity spectra data along a multi-channel seismic profile in the deep-water area of the South China Sea and by applying the velocity-depth linear model to the interpreted data of the profile, we obtained direct results for geological interpretation. In addition, through the creation of visual workflow and the consideration of horizontal variation of sedimentary interval velocity within the depth conversion procedures, we made the results of depth conversion more reliable. At the end, we discussed the limitation and further application of velocity-depth linear model in terms of both theory and practice, which would be considered in further work.
