| 英文摘要 | By fitting synthetic data to the seismic observations, full waveform inversion (FWI) uses the amplitude, traveltime, and phase information embedded in the recorded data to quantitatively extract the elastic rock properties and to provide reliable information for seismic imaging, velocity model building, and large-scale tectonic evolution interpretation, etc. However, the computational cost of FWI could be overwhelming, especially for large size 3D prestack seismic surveys. We compare FWI algorithms in both time domain and frequency domain and evaluate their pros and cons, respectively. Then we propose to implement FWI in hybrid domain and simplify the method to reduce production cost. To overcome the possible local minimum traps during the inversion, we propose to divide the model into several small pieces. The method computes the gradient of the objective function in each piece, compares all the local gradients and derives an optimal global inversion update. We implemented our simplified hybrid domain FWI method on GPUs. The numerical experiments reported in this paper demonstrate that our proposed inversion algorithm is effective, efficient, and scalable. |
