Static correction is an essential step in seismic processing and it has an effect on the later\nsteps of seismic processing, including velocity analysis, data stacking, and seismic inversion. During\nseismic data acquisition, a receiving point usually sets a geophone several times to receive the seismic\ndata. The same geophone cannot be set at the same receiving point every time. If the geophones have\ndifferent delay time, then the common receiving-point gather (CRG) will have multiple receiver statics.\nHowever, the receiver statics of a CRG are considered the same in conventional static correction.\nIn this paper, based on common attitude gather (CAG), a novel static correction method is proposed\nto analyze the receiver statics of a CRG. Attitude indicates the tilt angles of the three components of\na geophone. According to the different attitudes of geophones, CRG can be divided into multiple\nCAGs. When the difference technique is used to the novel method and the conventional method,\nthe statics are analyzed with CAGs and CRGs, respectively. A field example demonstrates that the\nproposed method cannot only enhance the continuity of the event in the shot gather, but also smooth\nthe gaps of the event in the CRG. The results suggest that the proposed method can eliminate the\neffect of differences in delay time of geophones on static correction.
