| 英文摘要 | Upgoing and downgoing waves are rich in VSP data. Based on the analysis of propagation paths and illumination ranges of VSP direct, upgoing, and downgoing reflection wavefields, we pointed out the defects of the conventional VSP wave equation migration method, and then proposed a joint imaging method of upgoing and downgoing waves by modifying wavefield continuation pattern. Under high-frequency approximation, we analyzed the imaging principle. This method can simultaneously image VSP primaries, free surface multiples, and interbed multiples without the needs of separating upgoing and downgoing waves. It has wider imaging range and better imaging results than the conventional imaging profiles. Moreover, this method is able to image downgoing primaries, thus it can image steep dip structures which can't be imaged by the traditional method. Processes of simulated and real field data proved the correctness of this method. |
