摘　　要：选取龙门山山前—华蓥山山前各年度施工的地震测线,通过各测线间的交接点关系,拼接形成贯穿四川盆地川西—川中地区的3条区域控制地震大剖面。并对这3条区域地震大剖面,运用Promax软件进行地震资料的叠前处理。在对资料进行分析的基础上,分析区域内干扰波对地震记录的影响,并且做好静校正处理,提高反射记录的品质。最终在精细速度分析的基础上,采用统一参数、流程对3条区域大剖面进行叠加处理,达到了预期的效果。Based on the seismic lines of both Longmenshan and Huayingshan foothills belts over the years and relationship of line intersection,3 large seismic section across west to center Sichuan basin were established.For these sections,a prestack processing is carried out by Promax software. The influence of disturbing wave within region on seismic record is analyzed,Furthermore,static-correction processing is implemented to improve the quality of reflecting record.Finally,in order to achieve a desired result,the stack processing of the three sections is done by the same parameter and procedure based on the fine analyzing velocity.
