中文摘要：

深地震反射剖面技术是探测岩石圈精细结构的有效手段．通常情况下工区地质情况复杂，尤其在盆山结合部位，地表地形起伏大，地下构造复杂，其深地震反射资料具有低信噪比、干扰强、构造复杂等特点，给后续处理和解释造成很大困难，因此获得真实的叠加剖面是地质解释的前提和基础．复杂地区低信噪比深地震反射资料处理的关键是做好静校正和去噪工作．本文以若尔盖盆地一西秦岭造山带接合部位深地震反射资料作为例，通过方法试验和参数测试，找到适合该工区的静校正方法和去噪技术，得到较好的处理结果，为揭示若尔盖盆地-西秦岭造山带结合部位的细结构提供了可靠的依据．

英文摘要：

The deep seismic reflection profiling is an effective method detecting the lithosphere fine structure. Usually, the geological situation is complex in work area. There are surface hypsography and complex subsurface structure in the basin-range contact zone especially. So its deep seismic reflection data have characteristics of the low S/N ratio, strong noise, the complex structure and so on. The features cause the difficulty for following processing and the explanation. So attaining reliable stacked section is precondition and base for following interpretation. The key steps of processing low S/N ratio deep seismic reflection data in the complex work area are static correction and noise removal. This paper used deep seismic reflection data of the contact zone between the Zoige basin-the west Qinling orogen as example for finding static correction and noise removal adapting to data of the contact zone after the method experiment and the parameter test. The final section provide the reliable basis for revealing the fine structure of the contact zone between the Zoige basin-the west Qinling orogen.
