Method and device for shifting shot points

An embodiment of the invention discloses a method and a device for shifting shot points. The method comprises steps as follows: sequentially determining shifting directions of the shot points on each measuring line according to distances between the shot points on each measuring line and edges of two sides of a barrier as well as the number of the shot points in positions, closer to the edge of one side of the barrier, of each measuring line; sequentially shifting the shot points on each measuring line according to the determined shifting directions; after shot points on all the measuring lines are shifted, sequentially judging whether the shot points on each measuring line are required to be smoothed or not; after judging that the shot points on each measuring line are required to be smoothed, sequentially smoothing the shot points on each measuring line required to be smoothed. The device comprises a determining unit, a shifting unit, a smoothing judgment unit and a smoothing unit. With the adoption of the method and the device for shifting the shot points, seismic wave fields can be sampled continuously.
