摘　　要：随着地震勘探技术的发展和勘探程度的提高,常规单一纵波勘探方法在解决复杂地质问题时往往达不到理想的效果,而多波地震勘探以其多分量信息的优势在一定情况下弥补了这一不足。本文对多波勘探中的纵波和转换横波联合勘探方法进行了一些定性研究,获得了一些有用的结论,希望对特定条件下野外地震数据采集有一定的指导作用。With the development and improvement of seismic exploration technology, conventional single P wave exploration failed to solve complex geological problems, however, multiple component exploration made it up well. Some qualitative examinations have been done in combined exploration of P wave and converted S wave and some conclusions have been obtained. We hope our research can provide guidance in field seismic data acquisition under some special conditions.
