摘　　要：江汉水网地区地表复杂,地震资料采集必须因地制宜采用不同类型的震源进行交替施工。利用炸药震源、可控震源交替施工所采集的资料,分析各自的特征及其在相位、能量和频率等方面的差异,对这两种不同震源类型的地震资料的匹配处理方法进行研究。实际处理中通过消除不同震源子波的相位和振幅差异,解决两种震源之间由于激发机制差异导致的不同相的叠加问题,实现同相叠加,提高剖面的准确度及信噪比。Due to complexity of the earth＇s surface in Jianghan water network region, different types of seis- mic sources have to be used by turns in field seismic data acquisition. Making use of data gathered respec- tively from explosive source and vibroseis, this paper analyzes their own properties and differences in their phase position, capacity as well as in frequency and carries out a study in the method to integrate seismic da- ta from these two different sources. In practice, removing variances of phase position and amplitude of wave- lets from different sources can remove out--phase overlapping caused by differences of triggering model be- tween two sources to ensure in--phase overlapping so that even more accurate seismic sections of higher quality can be provided.
