人们不断要求提高地震勘探的分辨率,已经导致了采集道的不断增加,这本身又使接收道距的逐渐减小,并降低了组合检波的空间滤波效应。 在过去的40年中,平均每7年道数翻一番(年增加率达12％),处理技术的不断进步,记录动态范围的大幅度提高,允许了噪声道存在,这样保全了信号中的高频成分。如果在以后十年中,采集技术能以相同比率提高,单检波
The constant demand for increased resolution of seismic exploration has led to an ever-increasing number of acquisition channels, which in turn leads to a gradual decrease of the receive track distance and a reduction of the spatial filtering effect of the combined detection. Over the past 40 years, the average number of tracks has doubled every seven years (an annual increase rate of 12%), advances in processing technologies, significant improvements in dynamic range, and the presence of noise channels, which have preserved the signal The high-frequency components. If in the next ten years, the collection technology can be increased by the same rate, single detection
