地震层速度在盆地分析中的应用
|
摘要
讨论了地震层速度在沉积盆地分析中的应用 ,论述了速度分析的基本原理 ,介绍了用相对剩余层速度进行岩性分析的方法 ,通过实例说明了速度分析的应用效果。指出层速度剖面图能明显地反映构造现象 ,层速度平面图能可靠地用于盆地构造分析 ,相对剩余层速度平面图能有效地预测岩性的变化 ,为沉积相和沉积体系分析提供可靠的依据。
The application of seismic interval velocity in depositional basin analysis is discussed.The principle about velocity analysis is expounded.The method on lithology analysis with relative residual interval velocity is introduced.With an actual example,the application effect of interval velocity analysis is illustrated.It is pointed out that interval velocity profile may show clearly the structural phenomenon.Interval velocity plane may be applied reliably to basin structural analysis,and relative residual interval velocity plane may forecast effectively lithology variation.This provides a reliable foundation for the sedimentary facies and sedimentary system analysis.
