应用层速度进行地层解释,常常受到层速度分辨率和计算精度的限制。层速度所能分辨地层的最小厚度为100～300米,而层速度的计算精度取决于原始地震记录的质量、排列长度和速度分析的精度。因此改进资料处理质量、提高速度分析精度是十分重要的,文中最后以实例介绍了层速度的应用。 Stratigraphic interpretation of the application layer velocity is often limited by the resolution of the layer velocity and the accuracy of the calculation. The minimum thickness of the stratum that can be distinguished by the layer velocity is 100-300 m. The calculation accuracy of the layer velocity depends on the quality of the original seismic record, the length of the arrangement and the precision of the velocity analysis. Therefore, it is very important to improve the quality of data processing and improve the accuracy of speed analysis. Finally, an example is given to introduce the application of layer speed.
