一、前言七○年起,我队就在赣抚地区开展地震勘探工作。在实践中,我们逐步认识到,该地区表层地震地质条件的变化是较大的,而且严重地影响着地震记录质量。因此,了解和掌握工区的表层结构,分析和研究记录变坏与表层地震地质条件的关系,对最佳激发条件的选择提供低速带校正参数和准确地判断深部地震地质条件的变化,都具有十分重要的意义。
I. Foreword In 1970, our team conducted seismic exploration in the Jiangxi-Fuding area. In practice, we have gradually realized that the change of the surface seismic geological conditions in this area is large and seriously affects the seismic record quality. Therefore, understanding and mastering the surface structure of the work area, analyzing and studying the relationship between the deterioration of records and the surface seismic geological conditions, providing low-speed belt correction parameters for the selection of the best excitation conditions and accurately judging the changes of deep seismic geological conditions all have very Significance.
