摘　　要：针对青东5地区滩浅海过渡带的地表特征,在对原始资料进行详细分析和研究的基础上,采用二次定位、互相关、模型法振幅调节和叠前时间偏移等关键技术,对拖缆漂移、不同震源及检波器差异和过渡带振幅能量异常现象进行了相应的研究和针对性的处理,这些技术的应用有效消除了滩浅海资料在振幅、频率及相位等方面的不一致性,最终取得了较好的成像效果,为该区域油气勘探开发提供了有利的支持。Based on surface characteristics of the regional beach shallow transitional zone of Qingdong 5 area and a detailed analysis of original data,the authors adopted quadratic secondary location,cross correlation,model method amplitude regulation and prestack time migration key techniques to study and tackle such problems as drag cable drift,different epicenters and detector differences as well as ecotone amplitude energy abnormal phenomena.These technologies can effectively eliminate the inconsistency of beach neritic information in such aspects as amplitude,frequency and phase and achieve good imaging effect.The achievements obtained provide support for regional petroleum exploration.
