| 摘 要： | 船噪声干扰是海上地震数据中的主要干扰源之一,由于大多数情况下具有侧面波的性质,常规去线性规则干扰的处理技术无法将其压制。采用空间域转换的方法,将共炮点域中的规则船干扰,转换为共偏移距域内的随机干扰,用现今流行的随机干扰压制技术,就可以达到压制船干扰的目的。文中给出了压制船干扰的实例。

| Abstract: | Ship noise interference is one of the major interference in offshore seismic data collection. In most cases, the ship noise interference has the property of lateral wave, and hence the traditional processing technique for eliminating linear regular inferences fails to suppress it. By employing the spatial domain transform method, the regular ship noise interference in the common shotpoint domain can be converted into stochastic interference in the common deviation distance domain, and by using the popular technique for suppressing stochastic interference, the aim of suppressing ship noise interference can be attained. The examples of suppressing ship noise interference are also given in this paper. |
