本文是渝鄂湘山地二维地震勘探近 30年来的方法研究和生产实践的经验总结。在详细介绍了本区地震地质条件的基础上,分析了在本区开展地震资料采集工作中的难点,指出并讨论了 4个方面的关键问题 :观测方法问题、地震波的激发问题、地震波的接收问题和施工组织管理问题。

This paper is a summary of researches and practices for 2D seismic exploration for nearly past 30 years in YU E XIANG carbonate mountainous districts. Based on a detailed review of seismic and geologic conditions at this region, the problems of seismic data acquisition are thoroughly analyzed and among them four key problems are singled out. They are survey layout, seismic wave excitation, seismic wave reception, and field organization management. The current status of seismic exploration in the region is illustrated with the seismic data from YU PI ZE area.
