Abstract
Full waveform inversion(FWI)is a method for accurately modeling the velocity and elastic parameters of underground strata based on the wave equation theory.With the large-scale application of nodal high-density seismic acquisition technology,the azimuth and offset of field-acquired seismic data have been greatly increased,which facilitates the implementation of velocity modeling via full waveform inversion.Based on the 3D long-offset seismic data of the SNSB Block in Shengli Exploration Area,the research and application of early-arrival-wave full waveform inversion technology were carried out.First,the original seismic data were preprocessed to improve the signal-to-noise ratio.Second,based on the initial velocity obtained by early wave tomography inversion and combined with the frequency-division multi-scale inversion strategy,the velocity modeling of early wave full waveform inversion in the block was realized.Finally,reverse time migration(RTM)imaging was performed to verify the accuracy of the velocity model.The application results show that the early-arrival-wave full waveform inversion technology can effectively improve the imaging quality and has obvious advantages over traditional inversion technologies.关键词
