摘　　要：本文针对滩海过渡带及多个相邻区块资料拼接的工区情况,提出了一系列的解决方案:包括匹配滤波因子的计算、时差的判别、相位差判别,频率匹配,异常能量压制,振幅补偿等联合处理方法,最终很大程度上实现了包括能量差、频率差、时差以及相位差的消除,有效解决了由于滩海过渡带地表条件极其复杂,地震激发、接收环境差、差异大而引起的地震资料分辨率与信噪比低、成像和一致性差的问题.As for the prospect composed of both seashore and marine ones, this paper gives a series of methods includes the calculation of matching factors, recognizing time difference, recognizing phase difference, matching frequency, suppressing of abnormal energy, frequency compensating and so on, to Move the attenuations of energy difference, frequency difference. They can time difference and phase difference, deal with the would-be problems, such as low signal to noise ratio, low resolution, poor imaging and poor consistent.
