摘　　要：在对压裂诱发微地震或天然微地震监测领域中,以地震射线追踪为主的正演环节直接影响震源定位质量以及计算效率。针对微地震监测特点,基于逐步迭代和中垂线点搜索法提出了一种新的三维追踪算法。该方法具有独特的灵活性与高效性。In the field of monitoring microseisms induced by hydraulic fracturing or natural causes, the seismic ray-tracing algorithm directly affects the quality of the source location and computational efficiency. Designed a new three-dimensional seismic ray-tracing algorithm, which uses a step-by-step iterative ray-tracing method, and mid-perpendicular point search method, this algorithm has the unique flexibility and efficiency.
