摘要
Based on the generalized synthesis of seismic data,a one-way wave equation migration method for generalized random synthetic gathers is proposed in this paper,through taking the generalized synthesis function in the generalized synthesis of seismic data as a time random function,and getting generalized random synthetic gathers and generalized random synthetic sources.The migration processing results from the numerical test and field data show that the migration method introduced in this paper gets the same migration result as that of conventional common-shot migration method,and has high calculation efficiency.
