海上地震数据全波形反演实际应用
The strategies of FWI realization for marine seismic data
摘要
Abstract
A ideal FWI result is so difficult to obtain in processing the field data.It is mainly due to the disaccord between the field data and the modeling data which is caused by that the initial model is not accurate enough,the wavelet is unknown and the data are noisy.It is also due to the high cost of FWI.FWI is put into practice in marine data.A workflow and some strategies of FWI realization for marine seismic data such as the estimation of the near-source wavelet based on the sea bottom reflection and the acceleration method for massive FWI computing like the L_BFGS method are also proposed.The FWI practice in marine data proves the capacity and validity of our proposed strategies.关键词
