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。
By analyzing the geological conditions and lithological differences in the Wanjiang area in Anhui Province, the physical parameters and the geophysical parameters of the main target strata of the study area were extracted by using synthetic records. Using indoor simulation to establish the observation system in this area, the 2-D seismic acquisition observation system was determined through field experiments to improve the signal-to-noise ratio and resolution of the section similar to that in the hilly region. Based on the investigation of low-velocity zone, Multi-string geophone combination of suppression of noise and a reasonable observation system for field data collection, can achieve better results.
