摘　　要：在地震勘探中,中深层信号受到高速层屏蔽、吸收衰减以及干扰波等因素的影响,有效反射能量弱。针对该问题,以高邮凹陷阜宁组三段(简称阜三段)为例,在分析了地震资料特征的基础上,研发了基于稀疏脉冲反褶积的透射补偿方法,并基于该方法进行了透射补偿,结合非均匀相干面波噪音压制处理技术对地震资料进行了针对性的处理。应用结果表明,针对性方法可以有效增强中深层的弱信号能量,从而为后续的波阻抗反演和储层预测提供高质量的数据。In seismic exploration,the middle-depth signals are affected by high-speed layer shielding,absorption attenuation,and interference waves,and the effective reflection energy is weak.To solve this problem,taking the third member of the Funing Formation in Gaoyou Sag as an example,based on the analysis of seismic data characteristics,a transmission compensation method based on sparse pulse deconvolution is developed.Based on this method,transmission compensation is carried out.And then combined with the technique of non-homogeneous coherent surface wave noise suppression,the seismic data are processed.The application results show that the targeted method can effectively enhance the weak signal energy in the middle-depth layers,thus providing high-quality data for the subsequent wave impedance inversion and reservoir prediction.
