利用矢量射线追踪正演模拟技术 ,计算地震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 ,我们对两种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、高精度的跨孔数据速度重建技术 Using vector ray tracing forward modeling technique, the path and travel time of seismic wave propagation are calculated, and then the iterative inversion technique of curved ray is developed by using ray traveltime and path interpolation. This method can be used to reconstruct the velocity image of wellbore strata. Development method, we reconstruct the crosswell velocity between the two more complicated typical geological models.The results show that this method is a fast, high-precision cross-bore data velocity reconstruction technique
