摘　　要：本文通过叠前深度偏移与地震常规处理方法的实例分析,说明叠前深度偏移技术在求准速度的纵横向变化;提高复杂构造和小断层的成像清晰度和精度;正确速度-深度模型建立上有明显的优势。可直接、精确地给出地质层位深度等优点。说明叠前深度偏移技术在断层探测资料处理中有很好的应用效果,并可结合勘察对场地作出准确评价;In this paper, according to the analysis of examples of depth-migration before stack technology and common earthquake processing methods, the conclusion indicates that the depth-migration before stack technology has great predominance in determining the longitudinal and transverse changes of velocities, improving the articulation and precision of imaging of complex structures and minor faults, properly establishing velocity-depth model. And the technology can be used to determine the depth of geological horizon directly and precisely. All of this proves the good application effects of the depth-migration before stack technology in the processing of the faults prospecting data. This technology, accompanied by the geotechnical investigation, can give the exact assessment for the construction site. All of the above shows that the technology has extensive application prospects in engineering prospecting.
