上下行波场反褶积衰减OBC表面多次波方法研究
|
摘要
OBC资料表面多次波问题非常严重.目前对OBC资料表面多次波的衰减方法是先将陆检资料与水检资料进行融合,然后使用拖缆数据表面多次波压制技术.本文开发了上下波场反褶积方法,通过陆检数据与水检数据在极性上的差异,将地震数据分解为上下行波场,然后将上行波场与下行波场进行反褶积运算,达到压制表面多次波的效果.该方法完全数据驱动,具有操作快捷,计算效率高等优点.通过理论模型与实际资料对该方法进行验证,取得了满意的多次波压制效果.
Ocean bottom cable free-surface-related multiple attenuation is a serious problem. But the method to attenuate the surface multiples now is merging the velocity data and pressure data at first,then using the multiple attenuation methods which used in the streamer data. In this paper,we use the difference between the velocity component data and pressure component data polarity to separate the wave field into up-going and down-going parts. Then,we can eliminate the surface multiples by deconvolution between up and down wavefield. This method is totally data driven and has the advantages of simple operating and high computational efficiency.The method has been proved to be robust for free surface multiples attenuation to theoretical models and real data.
