Abstract
AbstractBased on wavefront construction, an efficient algorithm for multivalued traveltime wavefield is presented. This method overcomes the difficulties with ray series method in conventional configuration space due to complex velocity structure by implementing the calculation in phase space instead. It solves out the required multi‐valued traveltime and amplitude at the uniform dispersed grids efficiently when applied to 3‐D prestack depth migration. Two criterions for controlling and balancing the global computational accuracy and efficiency are also discussed in this paper. The numerical examples show that our method is applicable to complex geological models.
