摘要
针对海底电缆勘探资料因鸣震干扰产生的陷频问题,采用了双检合并处理技术。由于压力、速度检波器的物理机制不同,在同一位置接收的鸣震干扰极性相反。在对两种资料进行一致性处理、提高信噪比处理、反褶积处理以及选择合适的合并方法等关键性处理后,鸣震干扰得到了有效压制,提高了海底电缆勘探资料的分辨率。
For the notch frequency resulted from the singing interference of the exploration data acquired by the o- cean bottom cables, the processing technique of sensor combination is adopted. Due to the different physical mech- anisms of the pressure sensor and velocity geophone, the received polarities of the interference are still on the con- trary, even in the same location. After processed by the key methods for these two kinds of data： consistency pro- cessing, signal-noise-ratio improving processing, deconvolution processing, selecting suitable means to process combinedly etc, the interference is effectively rejected and the resolution of the above data is enhanced.
