摘要
在城区、山地等野外复杂地表进行地震采集施工时,如果用室内设计的观测系统在实地进行炮点实际布设,炮点较理论设计位置偏移比率非常高,偏移优化后的炮点,应该使用原接收排列还是实际点位对应的新排列一直存在争议。通过观测系统属性定量分析方法对上述两套方案的覆盖次数、炮检距分布、PSTM响应的均匀性做了对比分析,得出较优方案,能够更好地指导野外生产采集过程中接收方案的选择,有一定的推广应用价值。
When we work in the urban,mountains and other complex areas for seismic ac-quisition , if the observttion system of interior design is applied for actual layout in practice, the ratio of position offset of shot point is very high,compared to the oretical design position. It has always been a controversial issue whether the offset shot optimized should use the original receiving arrangement or the new arrangement corresponding to the actual shot position. This paper takes contrastive analysis in the folds , offset distribution and uniform -ity of PSTM response of the above two sets of scheme by using the quantitative analysis method to observe system attribute and gets an optimal scheme which hava some application values to some extent and can give a better guidance in choosing the receiving program in the process of field acquisition and production.
