Near-field wavelet bubble period picking up method and system

The invention provides a near-field wavelet bubble period picking up method and system. The method comprises the steps of: obtaining a plurality of pieces of seismic wave sampling point information collected by a detector in a preset time period; traversing a two-dimensional array created by the plurality of pieces of seismic wave sampling point information, obtaining a maximum seismic wave intensity recorded in the two-dimensional array, recording the maximum seismic wave intensity as a first maximum seismic wave intensity, and determining the wave peak where the first maximum seismic wave intensity is arranged to be a wavelet pulse main peak; obtaining a reversing point of the wavelet pulse main peak; starting from the reversing point, searching the two-dimensional array for a bubble main peak; and determining the bubble period according to the wavelet pulse main peak and the bubble pulse main peak. By adopting the scheme provided by the invention, the near-field wavelet bubble period picking up speed and a
