Abstract:For residual static corrections,linear methods are easy to fall into local solutions and lead to poor seismic imaging in complex mountain areas.Therefore we propose in this paper a new approach with a niche genetic algorithm based on the Poisson disk sampling.First based on cnventional residual static corrections,real number codes are calculated with the Poisson disk sampling to increase the uniformity of the initial solution.Then multi-populations of niches are constructed with multi-threads to estimate residual statics based on "marriage" operation.Multi-core parallel calculations of machines can quickly search optimal residual statics within the multi-populations and their "marriage".Both theoretical model tests and real data applications confirm that the proposed residual statics approach can increase the event continuity and improve low signal-to-noise ratio (SNR) data imaging.
