摘要
由于涌浪的影响,浅剖资料海底反射同相轴抖动现象非常常见,对其进行研究十分有必要。从实测数据出发,利用涌浪静校正方法,消除了浅剖资料反射同相轴抖动现象。首先,利用软件自动拾取海底反射同相轴;然后,对拾取到的海底反射同相轴曲线平滑处理,以压制其他高频干扰;最后,计算每一道上涌浪引起的时间差,对每一个采样点进行校正。同时,对处理过程中的参数进行了分析试验,给出了各个关键参数的意义及设置依据。讨论了处理过程中可能遇到的问题,并给出解决办法。此涌浪静校正方法操作方便、效果良好。
Due to the influence of surge wave,in-phase axis jitters of seabed reflection are very common in sub-bottom profiles.Doubtlessly,it is a necessity to correct them.Based on real data,a set of methods is presented in this paper aiming at wave static correction of sub-bottom profile data.Various parameters for process and treatment are analyzed and tested.The significance and setting basis of some key parameters are described and provided.Possible problems and solutions in the process of treatment are also discussed and provided.The method is easy to operate and has good effect.
