海底电缆表面多次波衰减方法
|
摘要
海底电缆多次波衰减是国外地球物理研究的热点之一,国内研究关注相对较少,相应理论和实验研究相对匮乏。介绍了OBC多次波的压制方法,对上下行波场反褶积衰减海底电缆表面多次波方法理论及相应技术流程做出了详尽阐述。该方法不需要震源信息、不需要去掉直达波和鬼波,即可达到衰减表面相关多次波的目的,通过理论模型和实际资料的验证,取得了理想的效果。
Ocean bottom cable multiple attenuation is one of the hot topics in geophysics abroad.However,it has been ignored so far in domestic researchers due to lack of related theories and studies.This paper presents an up/down wave field de-convolution method and the corresponding technical process.This method does not need any source information and removing the direct waves and ghost waves previously,but can attenuate the surface-related multiples successfully by means of theoretical modeling and real data.
