The invention provides a method and a
system for obtaining seismic parameter
estimation, and the method comprises the steps: carrying out the
compressed sensing of a sparse seismic
signal in seismic map data, and constructing a seismic map
database; performing space division on the complete
signal of the seismic map
database, and establishing a first index; performing
compressed sensing on sparseseismic signals in the
seismic wave travel time information, and constructing a
seismic wave travel time table; performing space division on the complete
signal of the seismic
travel time table, and establishing a second index; inputting seismic event information, and performing
parallel search in the seismic map
database and the seismic travel
time table through the first index and the second index to obtain a search
result set; and determining matched seismic map data and
seismic wave travel
time information from the search
result set, and obtaining seismic parameter
estimation of the seismic event from the matched seismic map data and seismic wave travel
time information. According to the method, the seismic map database and the seismic wave travel
time table are constructed by adoptinga
compressed sensing technology, the influence of model difference on a search result can be reduced, and the
estimation of seismic parameters is obtained.
