| 摘 要： | 山东LK地区三维区块主要为海陆两栖带和浅海水域,地下勘探目标煤层埋藏浅,地震资料比较复杂。针对滩海浅层地震资料的特点及地质目标,利用SLS直达波二次定位技术,较好地解决了检波器的漂移问题,提高了浅层成像效果;运用子波校正技术,消除激发、接收因素造成的资料品质差异,实现了海陆资料的无缝拼接;采取两步法自适应反褶积,有效消除了海底鸣震;采用叠前时间偏移技术,很好地解决了浅海地区复杂构造的偏移成像问题。形成了一套适用于滩海地区浅层煤炭资源探查的地震资料处理技术,获得了具有高信噪比、高分辩率和高保真度的成果资料。 |
| 关 键 词： | 滩海浅层 检波器二次定位 变周期鸣震 叠前时间偏移 |

| Abstract: | The 3D block in LK area,Shandong is TZ zone and shallow water.Coal layers as target are shallower and seismic data is very complex.According to the seismic data characters and geological target in this area,many data processing technologies are researched including the SLS receiver secondary location,correction difference of shooting and receiving,Period-Varying Reverberation suppression,pre-stack time migration.One set of character-istic high-precision seismic data processing technology for shallow coal layer in Paralic Zone has been formed and achieved data are of high signal/noise ratio,high resolution and fidelity. |
| Keywords: | shallow layer in Paralic Zone receiver secondary location Period-Varying Reverberation pre-stack time migration |
