【摘要】 针对辽河滩海地区地震资料采集年度不同、资料品质差异大和存在的问题进行了大量的研究工作,在深刻认识原始资料基础上,在辽河滩海西部三维地震资料处理过程中运用了海底涌浪噪音衰减、聚束滤波多次波去除、自适应多次波衰减、连片拼接、高精度叠前时间偏移成像等技术,成功解决了以往小面积采集处理造成的边界效应问题,提高了成像精度,为后续的处理工作提供了技术储备。更多还原

【Abstract】 Liaohe tidal zone has become a new hot spot as Liaohe Oilfield Company had made an important discovery in the east of the area. Seismic data of Block 26 were acquired in different years, data quality differs a lot. The original data has been thoroughly studied, the 3D seismic data of Liaohe west tidal zone has been processed by using subsea surge noise attenuation, beaming filter multiple removal, adaptive multiple attenuation, block merging, and high precision prestack time migration imaging. The problem of boundary effect in processing previous small area acquisition has been solved; image precision has been improved, thus providing technical storage for further processing.更多还原
