This invention disclosed a seismic exploration method by cylindrical wave. The keypoints of the invention are as follows: On the basis of traditional two- and three-dimensional seismic exploration methods, applying a common receiver point stack after processing acquitted seismic signals by datum rectifying etc., synthesizing spherical wave into finite cylindrical wave reflection record profile; in the three-dimensional seismic exploration method, applying common center correction corresponding to the direction of crossline, common center stack so as to form cylindrical wave stacking profile, offset on the basis of cylindrical wave reflection so as to form cylindrical wave offset profile. Contrasting with the traditional spherical wave seismic exploration methods, more and more accurate subsurface geological information may be acquired by applying the two-and three-dimensional seismic exploration methods, there is important significance for researching fault, sand bulk, and abnormality of seismic oil and gas balance point. |
