摘　　要：在复杂地表条件的地方进行地震勘探时,因激发震源、检波器以及表层岩性不同会引起较大的子波差异,反射资料的品质较低。用两步法反褶积对炮点、检波点进行一致性处理,以消除炮点、检波点的差异。对一些实际地震资料进行了试处理,取得了较好的效果。During the seismic exploration in complex surface areas, the differences in excitation seismic sources, detectors and surface rocks would result in rather obvious wavelet differences and deterioration of the reflection data. In this paper, the two-step deconvolution is used for consistency processing of shotpoints and detection points so as to eliminate the differences in shotpoints and detection points. The tentative processing of some practical seismic data has proved its effectiveness.
