YF-SOLO-5Hz与DSU1地震检波器数据采集效果的对比分析

为了对比YF-SOLO-5Hz模拟检波器与DSU1数字检波器采集地震数据效果的差别,选择在淮南煤田某地震勘探区进行了针对性的野外试验.根据单一变量原则,采用相同观测系统同一炮点同时接收,对单只模拟检波器YF-SOLO-5 Hz和数字检波器DSU1的地震采集单炮记录及叠加剖面进行对比分析.试验结果表明,DSU1数字检波器...

Comparison and Analysis of Data Acquisition Effect between YF-SOLO-5Hz and DSU1 Geophone

To compare the difference of data acquisition effect of YF-SOLO-5Hz simular geophone and DSU1 digital geophone,a field test had been done in the field seismic exploration project at the coal mine in Huainan,Anhui Province.The data is acquired on the same survey system and or by the standard principal of single variable and taking the action of one shot point for all Geophones reciving signal in the same time.By comparing and analyzing the seismic data set and the seismic stack.The test results show that DSU1 digital geophone has a high sensitivity and the wide frequency band reciving ability,but the S/N is not so higher than that of the YF-SOLO-5Hz gophone;DSU1 digital geophone has a relative uniform capability to recivce both high and low frequency signal,especial a higher ability to recive high frequency,therefor is suitable to acquire high frequency signal;YF-SOLO-5Hz geophone has a higher ability to recive lower frequency signal than that of the DSU1 geophone,so is more suitable to acquire lower frequency signal data.
