摘　　要： 通过分析安徽皖江地区地质条件及岩性差异,利用人工合成记录提取物性参数及研究区主要目的层的地球物理参数。利用室内模拟初步建立该区观测系统,通过现场试验确定二维地震采集观测系统,提高类似该区(丘陵地区)的剖面信噪比及分辨率,采用以低速带调查为基础,优选激发参数、多串检波器组合压制噪声和合理的观测系统进行野外资料采集,可取得较好的效果。 Based on integrated analysis of geological condition and lithological differences in the Yangtze River valley in Anhui Province, physical parameters and main layer parameters were extracted through synthetic records. The indoor simulation was employed to preliminarily establish the initial observation system in this area, and then a 2D seismic acquisition and observation system was determined using in-site test. The research shows that better exploration results can be obtained through increasing signal-noise ratio and resolution observation, low velocity zone investigation based optimal excitation parameters, multi series geophone array noise suppression and reasonable observation system for field data acquisition in the profiles of hilly areas. Therefore, this study has certain significance to seismic data acquisition technology during shale gas geological survey in hilly areas.
