Abstract:High precision full waveform inversion depends on both low frequency seismic data and the initial model.However low frequency seismic information usually is not available and an inaccurate initial model will lead cycle skips.At the same time,inversions might cause multi-solutions and ill-posed problems.As well logging data is characterized by high resolution and broadband information,we take it as a constraint for full waveform inversion.We correct initial velocity models with reliable low frequency information extracted from logging data.Then we extend objective functions by a prior model,where the prior model drives optimization steps as a constraint to minimize the objective functions.Numerical tests on both EAGE overthrust model and real data show that the proposed inversion improves results.
