摘要本文所研究的墨西哥湾深海地震资料取自水深1900～3000m区域。该区盐丘发育,速度纵、横向变化大,多次波及涌浪噪声、外源噪声干扰严重。在进行地震资料处理时,针对上述特点,采用了相应的措施:①认真分析和检查电缆漂移对资料处理的影响,通过面元规则化等手段消除电缆漂移的影响;②选用合适的方法消除多次波、涌浪及外源噪声引起的干扰;③通过建立合理的叠前时间偏移速度场实现叠前时间偏移成像。

Abstract：The deep-sea seismic data in Mexico Bay thepaper studied comes from the region of water depth1900一3000m, which is characterized by developedsalt dome, large variation of vertical and horizontalvelocities and severe interference from multiple, surged waves and outside noises. During seismicdata processing, we adopted corresponding meas-ures to handle abovementioned characters:① care-ful analysis and checkup of the influence of feather-ing on data processing, which was reduced by binregularization;②selecting the appropriate ap-proach to diminish the interference from multiple, surged waves and outside noises;③the prestacktime migration imaging was implemented by build-up of reasonable velocity field of prestack time mi-gration.

Key words： wavelet multiple relative to surface streamer prestack time migration namgation
