| 摘 要： | 本文利用矢量射线追踪正演模拟技术计算地震波直达波传播的路径及走时,进而利用射线走时及路径的内插,发展了弯曲射线迭代反演技术.该方法可用来重建井间地层的速度图像.基于所发展的方法,我们对较为复杂的典型地质模型进行了井间速度重建.结果表明该方法是一项快速、高精度的走时层析成像技术.

| Abstract: | In this paper we calculate the ray-path and traveltimes of seismic wave with vector ray tracing, and then develop a technique to reconstruct the velocity image of acoustic media from direct traveltimes of crosswell data. The image of seismic velocity with a typical and complex geological model was present, which demonstrates the quickness and high precision of the rebuilding technique with crosswell data. |
