| description | The invention provides a seismic data splicing method and system, and relates to the technical field of seismic exploration. The seismic data splicing method comprises the steps that the overlapping range of original seismic data and seismic data to be spliced is analyzed, and according to the overlapping range, part of data is selected from the original seismic data to serve as foundation slab data; performing time difference, frequency and phase consistency processing on the foundation slab data and the to-be-spliced seismic data by applying a splicing technology to obtain first basic data and first spliced data; applying a relative amplitude fidelity technology to perform amplitude consistency processing on the first basic data and the first spliced data to obtain standard component data consistent with the amplitude of the original seismic data, and inserting the standard component data into residual seismic data except the basic bottom plate data in the original seismic data to obtain the seismic data.
