FIELD: statistics.
SUBSTANCE: present disclosure relates to a method for automatic recognition of a deposit center in a karst cave. According to the method, the rate substitution is performed based on a migration rate model in the time domain before summing to obtain a set of substituting migration rates. Migration in the time domain before summing is performed based on the set of substituting migration rates to obtain a set of seismic data volumes after summing. Three-dimensional cubic window is selected based on characteristics of a seismic response of the karst cave. Sparse statistical data of a seismic track or sparse statistical data of a seismic track attribute is obtained, respectively, from each of seismic data volumes after summing in the three-dimensional cubic window. The optimized migration rate and the optimized seismic track are obtained by determining the optimization.
EFFECT: increase in accuracy and informative content of obtained data.
