摘要
文章通过水层虚反射原理、多次波叠加特性理论、地震剖面和速度谱试验等方法研究 ,对空间频率与地震主频、气枪沉放深度、电缆沉放深度、电缆长度等主要采集参数的影响因素和变化规律进行了总结。在此基础上 。
On the basis of the theories of water zone ghosts and multiple reflection, this paper summarized the change rule and the main factors affecting the related parameters through the study of seismic section and velocity analysis, including the spatial frequency with dominant frequency, depth of source, depth of cable, length of cable, etc. Finally, the paper gave the method of marine seismic data acquisition parameters selection.
