摘　　要：井地地震技术是在井间地震方法基础上提出的,其技术的核心主要是观测系统的设计及数据采集和处理。首先简要地介绍了井地地震的工作原理及震源和检波器的选择,然后,阐述了建立正演模型和反演算法。最后,通过某工区实测的数据,利用相应的反演软件进行成图解释,其结果显示此技术在工程领域的良好应用效果以及在浅层地质调查,防治工程中的应用前景。The Wellground seismic technology was developed based on the crosshole seismic, the technical core of which pri marily is the design of observation system and collection and dis posal of data. The paper briefly introduced the working principle of the Welt ground seismic and the choice of source and detector, and described the establishment of forward model and inversion al gorithms. Finally, through a work area measured data, and by us ing the corresponding inversion software mapping explanation, the result shows that the technology has a good application effect in en gineering field, and application prospects in shallow geological in vestigation and prevention and control engineering.
