| 摘 要： | 多次覆盖折射波地震勘探是用来追踪反射波成像质量较差地区的地质构造或用于追踪深层基底形态及研究基岩面的一种勘探方法.基于折射波理论，用折射地震记录中的折射波对地下折射界面进行成像，应用共深度折射面元叠加成像理论方法，给出用共深度折射面元叠加成像技术对地下折射界面进行成像的速度分析与动校正计算方法，提出一种适用于折射波发育探区的共深度折射点叠加成像方法，最后以模型和实际例子说明方法的正确性和实用性.

| Abstract: | Multi fold refractive seismic exploration is generally used to trace the geological structural interfaces when the reflective seismic section is not good. It is used also to trace the base structural configuration and to study the base interface. This paper will discuss the theory and method of imaging underground refractors with the refractive seismic waves. The method was called common depth refractive segments stack imaging method. The velocity analysis procedure and NMO processing of the refractive wave by use of the theory and the method will also be given. A better imaging method,common depth refractive point stack imaging method,will be proposed in the paper. The exactness and the practicality of the methods will be verified by processing model example and real data. |
