SYSTEM AND METHOD FOR DERIVING SEISMIC WAVE FIELDS USING BOTH RAY-BASED AND FINITE-ELEMENT PRINCIPLES |
摘要 |
A system and method approximate a set of wave equations describing the propagation of seismic waves of one or more frequencies through a seismic volume of interest. In one embodiment, a ray-based initial beam solution is determined that describes the propagation of seismic waves at a first frequency through the seismic volume of interest as a set of one or more beams. Based on the ray-based initial beam solution, a refined finite-element beam solution is determined that describes the propagation of the seismic waves at the first frequency through the seismic volume of interest by approximating the two-way wave equation with a one-way wave equation. |
