摘要
以深水区域地质环境和地震资料采集方式为出发点,总结了深水地震资料的特征,包括海水速度变化大、地层各向异性影响突出、多次波复杂和崎岖海底成像困难等。同时,针对深水地震资料的特征,结合实际资料处理,对冷水校正、长电缆地震资料各向异性动校正、多次波压制和崎岖海底成像等深水地震资料处理关键技术进行了分析研究。
This paper discusses the characteristics of deep water seismic data including rapid water velocity change,noticeable formation anisotropy,complex multiples,and difficulties in imaging in rough seafloor.We demonstrated with real data processing the key technologies in deep water data processing such as correction for cold water effect,anisotropic moveout correction for long cable seismic data,multiples suppression,and imaging in rough seafloor.
