摘要
共聚焦点 (CFP)偏移 (激发聚焦和检波聚焦的双聚焦偏移 )是一基于等时原理的地震成像方法。通过时空域的零走时成像原理 (CFP偏移的共聚型 )和拉冬域的零截距时间成像原理 (CFP偏移的双聚型 )分别实现构造成像 (角平均的标量成像 )和岩性成像 (考虑AVO的矢量成像 )。通过模型试算了CFP偏移的共聚型成像 。
Common focus point migration (CFP), which is a bifocal migration method that focuses both in emission and detector, is a new seismic imaging method that is based on the principle of equal traveltime. Confocal version of CFP migration that is used for structural imaging was realized by the zero traveltime imaging principle in time domain. Bifocal version of CFP migration was accomplished by the zero intercept time imaging principle in Radon domain. The effectiveness of the confocal version of CFP migration was verified on a model.
