英文摘要：

The eighteen years of research on oil reservoir geophysics during the second round of hydrocarbon exploration provided a sound basis for the proposition of an effective expression of wave field based on structure preserved algorithm and pseudo-differential operator technique. The expression transfers operator calculation into function calculation and multiplication into summation and promotes the development of rapid and effective methods of seismic wave field calculation and data processing. Various techniques such as high-precision depthvelocity estimation, asymmetric travel-time migration, multiple prediction through pre-stack spectrum decomposition, elastic inversion, and dealias reconstruction, are continuously sharpening in the process of practical applications with real data.
