Strategy study on full waveform inversion for the land seismic data
摘要
Abstract
Full waveform inversion of marine seismic data has been successfully applied,however,the application of this technology for onshore seismic data faces many difficulties.In this study,a robust strategy of full waveform inversion for onshore seismic data is presented.Firstly,the phase-matched cross-correlation cost function is adopted to improve the applicability of full waveform inversior.Secondly,dynamic wavenumber domain gradient preprocessing method is used to suppress gradient noise.Finally,an adaptive Gaussian smoothing operator is applied to improve the quality of inversion results.The inversion case of two-dimensional onshore seismic data shows that this strategy presented in this study can effectively realize high wavenumber onshore seismic data velocity modeling.关键词
