三分量检波器埋置误差分析
|
摘要
本文推导出了三分量检波器由埋置不准引起的误差计算公式，讨论了三分量检波器的方位偏差和倾斜偏差的允许范围，得到了野外采集时允许偏差的结论：①以10％的误差作为界限，偏差角度应控制在3°左右，进行三分量地震采集可以此为参考；②以5％的误差作为界限，偏差角度应控制在1°左右，进行九分量地震采集可以此为参考。
The formula for planting error of three-component geophone is presented here.After analysis,the authors offer the following allowable errors in azimuth and incli-nation of three cornponent geophone in field data acquisition:(1)When error limit is 10%,the angle deviation will be about 3°,which can bethe reference value for three-component seismic data acquisition;(2)When error limit is 5 %,the angle deviation will be 1°,which can be the ref-erence value of nine-component seismic data acquisition.
